Abstract:

    This paper reports the releasing of green lacewing (Mallada basalis (Walker)) as a biological control agent for insect pests of sweet peppers in net houses.  Surveys of insects on sweet peppers were undertaken as references for the control.  The mealy bug, Phenacoccus sp. was found for the first time on sweet peppers.  Three lacewing larvae were released on each plant in a seven days interval throughout the growing period. Results showed that populations of A. gossypii, B. argentifolii and Phenacoccus sp. were depressed effectively. Fruits harvested from lacewing-released plants were heavier, larger and having a better shape than CK.

Key words:Mallada basalis, Sweet pepper, Biological control
