ABSTRACT: Notes on the bio-ethology of P. unionalis are reported. Damage on different plant species, particularly Jasminum sp., are described. The biological cycle of P. unionalis was studied under laboratory conditions: at 15-25°C the developmental periods were 3.5 days for the egg, 14.8 days for the larva and 7.0 days for the chrysalis. Under greenhouse conditions, in an entomological cage, P. unionalis completed 6 generations per year and the adult to adult time was about 67.8 days. Information concerning natural enemies and control methods are reported.

ABSTRACT: Some aspects of Apanteles syleptae, a parasitoid of Palpita unionalis, namely the duration and description of the development stages, longevity, parthenogenesis, host-searching and oviposition modality were examined. The duration of egg incubation was about 46-48 hours; the egg-larval development was, on average, 12±0.2 days for males and 13.6±0.4 days for females and the pupation period was, on average, 11.3±0.4 days for males and 14.1±0.6 days for females. The entire development cycle was, on average, 31.4±0.8 days for males and 35.3±0.9 days for females. The last instar larva of the braconid emerges from the host and, bending in a "U" fashion, feeds on the internal contents of the host body. The cocoon is spun with silk threads for pupation for about 6 hours. After 2 days the parasitoid turns into a pre-pupa and after 3 days into a pupa. After 7 days, the adult emerges forcing a cap-like operculum in either pole of the cocoon. The longevity was, on average, 17.2±1.0 days for fed males, 11.5±0.3 days for fed females, 2.1±0.4 days for unfed males and 1.0±0.0 days for unfed females. A. syleptae females exhibited arrhenotokous parthenogenesis. Females search the host through antennal drumming on the substrate and are often attracted by larval faeces. When the female encounters a host it evaluates its acceptability with insertions of the ovipositor in the host body; generally, the first and second instar larvae are selected. The oviposition sting, which lasts about 4-5 seconds, temporarily produces immobilization of the larval host. The percentage of parasitism reached its peak during the autumn months (73.33% in October) and was very low during the spring and summer seasons. The sex-ratio (males/females) varied from 1:1.8 (December 1992) to 1:3.6 (January 1993).

ABSTRACT: Over the last few years, Palpita unionalis has been noted causing damage to olive in Sicily, especially to young trees in nurseries and new plantations. Notes are given on the morphology, bio-ethology, injuriousness, control and natural enemies of the pest. In some cases, infestations can exceed levels which require chemical intervention, but generally control is effected by the use of certain agronomic practices and the activity of naturally occurring natural enemies, especially the braconid Apanteles syleptae.

ABSTRACT: The principal insect pests of olive in Italy are listed; they are almost exclusively represented by species of Thysanoptera (eg. the phlaeothripid Liothrips oleae), Lepidoptera (eg. the yponomeutid Prays oleae, the cossid Zeuzera pyrina and the pyralid Palpita unionalis), Coleoptera (eg. Scolytidae and the curculionid Otiorhynchus cribricollis), and Diptera (eg. the tephritid Dacus oleae [Bactrocera oleae]). B. oleae is considered to be the key pest of olive and control methods have been formulated based on monitoring the adult flight using various kinds of traps and knowledge of larval infestation, fruit drop and damage. Field technicians play an important role in acquiring information necessary to plan strategies in the integrated protection of olive. If correctly applied, these control strategies prevent key pests from exceeding economic thresholds, prevent outbreaks of secondary pests, give products of a higher quality, and protect workers, consumers and the environment.

ABSTRACT: (E)-11-Hexadecenal and (E)-11-hexadecenyl acetate were found in abdomen tip extracts from females of Palpita unionalis. The identification was based on capillary GC analyses, mass spectrometry, and laboratory and field tests. In laboraotry bioassays, both components elicited a low level of upwind flight by males. The 2 components when tested separately in olive groves in Greece during 1991 were inactive, but a blend at a ratio of 3:7 was highly attractive to males. Traps baited with 1 mg of the 2-component blend were comparable to traps baited with 5 virgin females. The addition of (Z)-isomers of the components reduced male capture.

ABSTRACT: Laboratory tests were conducted to evaluate the influence of constant temperature (10, 13, 15, 18, 20, 23, 25, 28, 30, 33 and 35°C) on the embryonic development of Palpita unionalis. There was 100% mortality at 10 and 35°C. The thermal constant was between 57.8 and 63.3°C/day. The mortality rate remained below 50% between 13 and 30°C, results which suggested that eggs could still hatch despite a sudden drop in temperature, which often occurs during spring in the Mediterranean (adults in southern Italy were flying by March). The average number of eggs laid/female at 20 and 25°C was about 320. The average longevity of females and males was 13.5 (minimum 8, maximum 27) and 15.3 (minimum 7, maximum 30), resp.

ABSTRACT: This paper was presented at the International Symposium on Olive Growing, held in Cordoba, Spain, on 26-29 September 1989. The biology of the pyralid Palpita unionalis was studied in the laboratory and in olive groves in Sicily during 1988. Five generations were recorded in the field using light traps, with a generation time of 29-38 days. The ratio of males to females wsa 1:1.16. In the laboratory, the life cycle lasted 24 and 39 days at 17 and 26°C, resp. Parasitism of 2nd- and 3rd-instar larvae by the braconid Apanteles xanthostigmus was 30-35%. Control of 1st- and 2nd-instar larvae was achieved following treatment with 0.03% methidathion, 0.14% fenthion, 0.06% dimethoate, 0.09% carbaryl or 0.006% Bacillus thuringiensis.

ABSTRACT: The biology, injuriousness and control of the pyralid Margaronia unionalis [Palpita unionalis] on olive were studied in the laboratory and field in Sicily in 1986-88. The pest had 5 generations in 1988. The male:female ratio was 1:1.16 and the life cycle was 24-30 days in the laboratory and 29-38 days in the field. The pyralid damaged the first 3 verticils of the apical and lateral buds. Irrigated plants recovered from the loss of vegetation. Up to 90% of the branches were damaged by the pest but loss in total olive production did not exceed 20%. Parasitism of larvae by field -collected females of Apanteles xanthostigmus varied from 30 to 35% in the laboratory. Sprays of 0.03% methidathion, 0.14% fenthion, 0.06% dimethoate, 0.09% carbaryl and 0.006% Bacillus thuringiensis gave good control at the beginning of infestation when larvae were in the 1st and 2nd instar.

ABSTRACT: A total of 12 arthropod species was found on the leaves of olive trees on 2 sites in Alexandria, 2 in Tora and 4 in Fayoum districts of Egypt. Of the 3 diaspidid scales found, Leucaspis riccae and Parlatoria oleae were important pests of olive; the yponomeutid Prays oleae and the pyralid Palpita unionalis, 4 phytophagous or possibly phytophagous and 4 predacious species of mites, and the braconid Apanteles syleptae (parasitising the nymphs of P. unionalis) were also present. The study of the population densities of the diaspidids showed that L. riccae had 4 population peaks in Tora and Fayoum and 3 in Alexandria, and Parlatoria oleae had 3 peaks in Tora and Fayoum and 2 in Alexandria. The scale insects migrated from the leaves to the fruits at the beginning of July.

ABSTRACT: A Trichogramma egg parasite reared from eggs of Palpita unionalis (Hb.) (Glyphodes unionalis) on olive in Yugoslavia and from those of Prays oleae (Bern.) on olive in the Alpes-de-Haute-Provence region of France is morphologically close to T. evanescens Westw., but sufficient other differences have been found between the 2 to warrant affording it specific status. The parthenogenetic females of the new species (which is to be described [see next abstract] as T. oleae sp.n. by J. Voegele and J. G. Pointel) at first produce female progeny then, with increases in temperature, male progeny. Between these 2 phases, intersexes are produced. The specific status of T. oleae is supported by the genetic distance, calculated from the gene coding for 9 esterase loci, between it and T. evanescens and T. embryophagum (Htg.).

ABSTRACT: Apanteles syleptae Ferriere has been found parasitising larvae of the moth Palpita unionalis (Hb.) in Egypt, apparently for the first time. In order to study its morphology and life-cycle, parasitised larvae were collected in two localities and olive branches collected in the same localities in the years 1971-73, and examined for parasitism. All stages of the braconid are described, with special reference to the genitalia. Studies on its bionomics showed that the adults lived for 8.4-14.9 days according to the season; the female:male ratio was about 1:0.7. At an average temperature of 25.2 deg C, the egg and larval stages lasted 6-8 days and the pupal stage 5-6 days. The percentage parasitism varied considerably and was highest in summer. Figures are given for different months in the two localities, the highest recorded being 92% in June 1973 at one of them. It is concluded that the parasite plays a part in the regulation of P. unionalis numbers.

ABSTRACT: An unidentified species of Trichogramma that had been reported by C.D. Pelekassis parasitising Prays oleae (Bern.) and Palpita unionalis (Hb.) [on ollve] in Greece [cf. RAE/A 52, p. 477] and by A. Tominic on the same hosts and Hylesinus oleiperda (F.) in Yugoslavia was imported into Greece from Yugoslavia and reared in the laboratory on eggs of Ephestia kuehniella Zell. (Anagasta kuehniella), Spodoptera littoralis (Boisd.), Cacoecimorpha pronubana (Hb.) and P. unionalis.At 21-25 deg C, fecundity was highest (46.4 eggs/female) when adult females were fed on a mixture of honey with yeast hydrolysate, and lowest (28.0 eggs/female) for honey alone. The ratio of males to females in the progeny varied from 0.026 to 1.26, and parthenogentic reproduction took place. At 21 deg C, the duration of adult life averaged 5.0 days on honey and 6.7 days on honey with yeast hydrolysate. At 18 deg C, the duration of adult life averaged 5.2 days, but the fecundity was low (13.8 eggs/female). When females were provided with water only they lived for 2.5 days and laid 10.0 eggs/female, no males appearing in the progeny. The life-cycle was completed in 10-12 days at a temperature of 21 deg C and a light intensity of 500 lx, and in 9-10 days at 25 deg C and 1000 lx.

ABSTRACT: The Pyralid Palpita unionalis (Hb.), which is one of the principal pests of olive in northern Egypt, was reared on olive in the laboratory for observations on its bionomics. The eggs were laid in groups of 2-86, though in the field they are usually found singly or in groups of 2-6. The eggs hatched in about three days in summer and nine days in winter. The larvae fed on the leaves at the end of the twigs, forming silken webs in which they sheltered and later pupated. The six larval instars together averaged about 15 days in summer and 23 in winter, the prepupal stage averaged about 1-1.6 days in summer and 2.5 in winter, and the pupal stage averaged about 9 days in summer and 17-18 in winter. Adults paired soon after emergence and oviposition began after 2-3 days. The females laid 141 -882 eggs each. There were 10 overlapping generations a year.

ABSTRACT: The biology of Palpita unionalis (Hb.) is described from observations on olive in the field and laboratory in Egypt in 1970-71. In 1970, the peak of infestation in the province of Alexandria occurred in May, but in 1971 (when conditions had been unfavourable for the growth of olives) the population reached its maximum in July. A species of Apanteles, believed to be A. syleptae Ferriere, was found parasitising larvae in the field. In the laboratory, the egg stage varied from 3 days at 30 deg C to 12 days at 15 deg C. There were six larval instars, the duration of the larval stage being shortest (15.6 days) at 30 deg C. At 15 and 20 deg C, the pupal stage averaged 31.2 and 17.1 days, respectively, for males and 23.4 and 15.7 days for females. The most favourable relative humidity for adult emergence was 65%, at which 90% emergence occurred. Mating took place 24 h after emergence, and at 27.5 deg C and 66.5% R.H. the preoviposition and postoviposition periods were 2-4 and 4-7 days, respectively. The numbers of eggs laid by fertilised females averaged 414, the highest number of eggs being laid during the first day. Terminal rows of leaves were preferred as sites for oviposition, and more than 60% of the eggs were laid singly. In the laboratory, there were nine generations a year, development being fastest (26.2 days) in July and slowest (66.2 days) in November.

ABSTRACT: Palpita unionalis (Hb.) is a pest of olive and jasmine (Jasminum sp.) in Greece, feeding on the leaves of the young growth, and has also been reported from several tropical and subtropical parts of Asia [cf. RAE/A 51, p. 479; 59, 84], Africa, Europe [4, p. 206] and Australia. Observations were made on the bionomics of this Pyralid in the laboratory (beginning with adults caught in the field in light-traps) with a view to facilitating control. At a temperature of 23.4 deg C and 65% R.H. the larval stage lasted 21 days on privet [Ligustrum japonicum] and 25 days on lilac [Syringa vulgaris] or jasmine; at 25-27 deg C and 73-77% R.H. it lasted 21-26 days on olive, 15-21 days on privet and 24 days on lilac. Females were only slightly more numerous than males, and they were able to mate more than once. The number of eggs/female varied between 86 and 515. Development on detached branches in the laboratory appeared to take longer than development in the field. The failure of larvae to develop on olive shoots in the laboratory was probably due to rapid dehydration of the young leaves on which the larvae fed. It is concluded that privet is the best plant for laboratory rearing of P. unionalis.

ABSTRACT: Palpita (Margaronia) unionalis (Hb.) has recently caused considerable damage to olive in the region of Puglia in Italy, especially near Taranto, destroying the leaves on newly planted young trees and on the suckers of old trees. All stages of the Pyralid are described (the larva in detail) and, from observations in 1969-71 and from the literature, information is given on its distribution, food-plants, life-history and natural enemies. In southern Italy, all stages were observed almost throughout the year, and all stages (but mostly the second- and third-instar larvae) overwintered. The first adults appeared in March-April. The eggs were laid in a row on the lower surface of the leaf against the midrib and hatched after 15-16 days. During heavy infestations, the fruits as well as the leaves were attacked. Pupation took place in a shelter of leaves held together with silk. Natural enemies comprised spiders, the predator Syrphus corollae F., and the larval parasites Apanteles xanthostigmus (Hal.) and Nemorilla maculosa (Mg.), notes on the life-history of which are given. The best method of controlling P. unionalis is to remove the suckers from older olive trees, which if attacked do not suffer severe damage but act as a source of infestation for nurseries and new plantations, where the consequences of defoliation are serious. Young trees already infested should be treated with systemic insecticides such as carbaryl (Sevin) at 250 g/hl.
