AB: The biology of Leucaspis pusilla was studied in pine forests in Tuscany, Italy. The diaspidid was common in coastal areas on Pinus pinaster, P. pinea and P. halepensis. The pest completed 2 generations a year, overwintering in the 2nd larval instar. Adults of the 2 generations started emerging at the beginning of April and in late July, resp. The morphology and development of the various life stages of both generations are described. The aphelinid Encarsia leucaspidis was recorded parasitizing the pest. L. pusilla caused much damage in some of the pine forests in which trees had already been weakened by abiotic or biotic factors.

AB: An outbreak of Matsucoccus feytaudi Ducasse on Pinus pinaster in the Ligurian region of Italy in 1978 is reported, and the results are given of investigations in 1978--80. This scale insect was not previously known in Italy, and it had been supposed that the variety of P. pinaster grown in parts of that country near the border with France (where M. feytaudi was common) were resistant to the pest, or that forests in the border region that were largely composed of P. halepensis (which is not a food-plant of M. feytaudi) had blocked its penetration into Italy. The characteristics of the infestation indicated a recent introduction of the pest into the Ligurian region. The symptoms of attack included yellowing and withering of the needles, peeling of the bark, waxy secretions and exudation of resin. Eggs were present in the forest from mid-January to the end of May, 1st-instar nymphs from February to early October, 2nd-instar nymphs from late August to the middle of the following April, male pupae from late December to mid-April, and adults of both sexes from January to the end of April or early May. Other insects infesting P. pinaster at the same time included the scale insects Anamaspis lowi (Colv.) (Leucaspis lowi Colv.) and L. pusilla (Lw.), which caused similar damage to M. feytaudi, and the weevil Pissodes castaneus (Deg.) (notatus (F.)), which attacked trees already weakened by M. feytaudi and intensified the symptoms of bark peeling, exudation of resin and drying out of the whole tree.

AB: Diaspidids were sampled on Pinus species at 135 sites throughout Israel. Three species were found: Leucaspis pusilla, L. knemion and (more rarely) L. loewi. L. pusilla was found at every site, but never on P. pinea. L. knemion occurred only in the north, mainly on young P. pinea. Most of the damage due to diaspidids in Israel is probably due to this species.

AB: During a survey of scale insects on conifers in natural and artificial forests, parks and roadside avenues in Italy in 1973-74, 6 species were found, of which Syngenaspis parlatoriae Sulc is recorded (for the first time in Italy) at Agordo on Pinus nigra, on which it has not been reported in any other country; the newly hatched nymph is described. Details are given of the distribution within and outside Italy and of the food-plants of this species and also of Leucaspis pini (Htg.), L. pusilla Lw., Anamaspis lowi (Colv.) (L. lowi), Dynaspidiotus abietis (Schr.) and Insulaspis newsteadi (Sulc) (Lepidosaphes newsteadi).

AB: Little is known of the bionomics of Leucaspis pusilla Lw., which damages the needles of pine trees in Italy. Following observations in Campania in 1968-69, details of its life-history are set out in a table. Two separate life-cycles occurred according to the stage in which the Coccid overwintered. Most individuals overwintered as second-instar nymphs, remaining in this instar from June until the following March or April and giving rise to adults in March-July and to the eggs and nymphs of the next generation in April-August. The Coccids that overwintered as adult females from August to the following April produced eggs and young nymphs from late March to the end of May, second-instar nymphs in May-July, males from mid-June to the end of August and females from August onwards. Three parasites were recovered from L. pusilla, Aphytis sp., which was rare, and Prospaltella leucaspidis Merc. and Azotus atomon (Wlk.), on which morphological and biological notes are given. P. leucaspidis, which gave 30-40% parasitism, is an internal parasite overwintering as a young larvae in the host nymph or female and giving rise to adults from late April, first-generation eggs and larvae from May, new adults from mid-June, second-generation eggs and larvae from late June, adults from August and third-generation eggs and larvae from September. Azotus atomon oviposited either directly into the female of L. pusilla or on to the larvae of a primary parasite (P. leucaspidis or its own species) within the Coccid female; it thus gave only 10% parasitism of L. pusilla. Azotus larvae parasitising L. pusilla directly developed internally and usually gave rise to females, and those acting as hyperparasites fed externally and usually gave rise to males. Since the control afforded by these parasites is not adequate to suppress heavy infestations by L. pusilla, the authors recommend supplementing it by applications of light mineral oil emulsion in May-July.

AB: Describes a study in 1968-69 of the bionomics of L. pusilla, a little- known coccid damaging Pine needles in Italy, with tabulated details of its life history (univoltine, with two distinct life-cycles for individuals wintering as second-instar nymphs and adults respectively). Three parasites were recovered, two of which were further studied: Prospaltella leucaspidis, giving 30-40% parasitization, with 3 generations/year; and Azotus atomon, either a primary parasite or a hyperparasite on P. leucaspidis, giving only 10% parasitization of L. pusilla. Since the control by the parasites was inadequate to suppress heavy infestations, it is recommended that it be supplemented by applications of light mineral oil emulsion in May-July.
