Abstract

Experiments on development of Amblyseius longispinosus Evans (Acari:Phytoseiidae) as influenced by castor pollen as an alternate food and its interaction with sorghum mite, Oligonychus indicus Hirst (Acari:Tetranychidae) were conducted under laboratory conditions. A. longispinosus showed poor growth on castor pollen. Female and male developmental periods were 2.6 ± 0.30 and 2.42 ± 0.21 days on spider mites, 2.70 ± 0.89 and 2.68 ± 0.39 days on spider mites + castor pollen and 5.12 ± 2.03 and 3.89 ± 1.80 days on castor pollen alone, respectively.

At interaction A. longispinosus suppressed populations of O. indicusat 1:10, 1:20, 1:30, 1:40 and 1:50. Prey elimination was on 12th day in 1:10, 18th day in 1:20, 20th day in 1:30, 24th day in 1:40 and on 30th day in 1:50 ratio.

Résumé

Des expérience ont été conduites au laboratoire sur le developpement d'Amblyseius longispinosus Evans (Acari: Phytoseiidae) tel qu'influencé par le pollen de ricin qui est une source alternative de nourriture et ses interactions avec l'acarien du sorgho, Oligonychus indicus Hirst (Acari: Tetranychidae). A. longispinosus a montré une faible croissance avec le pollen de ricin. Les périodes de developpement du mâle et de la femelle ont été de 2.6 ± 0.30 et 2.24 ± 0.21 jours pour l'acarien prédateur, de 2.70 ± 0.89 et 2.68 ± 0.39 jours pour l'acarien tisserand + pollen de ricin et de 5.12 ± 2.03 et 3.89 ± 1.80 jours pour le pollen de ricin seul respectivement.

Concernant les interactions, A. longispinosus a éliminé des populations de O. indicus dans un rapport de 1:10, 1:20. 1:30, 1:40 et 1:50. La disparition de la proie survenait au 12e jour, 18e jour, 20e jour, 24e jour et 30e jour correspondant respectivement aux ratios ci-haut.
