Mass production, releasing and evaluation of the lady beetle, Coccinella undecimpunctata (Coleoptera: Coccinellidae), for control of aphids in Egypt
Archives of Phytopathology and Plant Protection 41 (3), 187-197
Abstract: Coccinella undecimpunctata L. (Coleoptera: Coccinellidae) is one of the most effective bioagents for control of aphids in Egypt. The present work deals with mass production, releasing and evaluation of this predator on different aphid pests including Aphis gossypii Glover on cotton, Brevicoryne brassicae (L.) on cabbage, Aphis craccivora Koch on potato, Myzus persicae (Sulzer) on apple, Aphis nerii (Boyer de Fonscolombe) on oleander and Pterochloroides persicae Chlod. on peach. Experiments were carried out in four different locations of Egypt including Qalubiya, Demmyate, North Sinai and Giza. About 2.22 million eggs were released, biweekly, during 2003 - 2004. Eggs were assessed monthly during 2004 by counting aphid stages and larva and pupa of C. undecimpunctata. The results show that the populations of aphid species decreased from 3115 - 11, 1062 - 315, 2110 - 28, 1945 - 310, 1152 - 310 and 4350 - 76 individuals/10 leaves on cotton, apple, cabbage, peach, potato, oleander, respectively after releasing C. undecimpunctata. Significant reductions in some aphid predators and parasitoids also occurred.
