Biological control of Aphis gossypii on pepper plant using Coccinella algerica.

摘要: To calibrate biological control in pepper plant against Aphis gossypii using Coccinella algerica different experimentation were made. The consumption of C. during the larval stage was enumerated laboratory conditions. densities (1, 4, 8 larvae/plant) to L2 necessarily decrease aphid's populations determined and daily at calculated. density with larvae semi natural conditions is higher significantly. In protected crop pepper, releases made eggs, second larva ladybird before infestation A. gossypii. A strategy introduce preferred than release punters densities. At same, Introduce compared crops. activity has been maintained it shown when appeared.
