Abstract

Attempts were made to reduce populations of San Jose scaleQuadraspidiotus perniciosus (Comstock) by releasing populations of the parasiteEncarsia (=Prospaltella) perniciosi Tower. Several releases were made, between May and November in both 1985 and 1986. TheEncarsia were released into 2 apple orchards infested with scale. Increases in the numbers ofEncarsia caught on sticky traps in these orchards, coupled with an increase from 2.3% to 9.1% in the overall level of parasitism of the scales, suggested that the released parasites had become established. Other natural enemies found associated with San Jose scale on apple in Kashmir included 3 parasites (Marietta carnesi Howard,Azotus kashmirensis Narayanan andAphytis paramaculicornis De Bach) and 5 predators, 4 of which were coccinellids (Chilocorus bijugus Muls,Pharoscymus flexibilis, Exochomus sp. andCoccinella septempunctata) and the remaining one was a chrysopid (Chrysoperla carnea).

Résumé

Des essais ont été réalisés pour réduire les populations de Pou de San José (Quadraspidiotus perniciosus Comstock) au moyen de lâchers d'Encarsia ( = Prospaltella) perniciosi Tower. On a procédé à plusieurs lâchers entre mai et novembre en 1985 et 1986. LesEncarsia ont été libérés dans 2 vergers de pommiers contaminés par la Cochenille. L'augmentation du nombre d'Encarsia capturés au piège englué dans ces vergers et l'accroissement du taux de parasitisme de 2,3 à 9,1%, suggèrent que les parasites lâchés se sont établis. Les autres ennemis naturels associés au Pou de San José sur pommiers trouvés au Cachemire comprennent: 3 parasites (Marietta carnea Howard,Azotus kashmirensis Narayanan etAphytis paramaculicorius De Bach) et 5 prédateurs dont 4 sont des Coccinellides:Chilocorus bijugus Muls,Pharoscymnus flexibilis, Exochomus sp. etCoccinella septempunctata) et le dernier un chrysope (Chrysoperla carnea).
