Abstract
This study was conducted to survey the major piercing sucking insect pests
and their associated predators during summer crop of okra plants in the two
successive seasons, 2003 and 2004, in Qalubla Governorate. The maximum total
numbers of Aphis gossypil individuals were recorded during the last and third week of
August, 2003 and 2004, respectively. The maximum numbers of Bemisia tabaci
individuals were counted with their maximum numbers ¡n the second week of August,
2003 and 2004. The jassids, Empoasca spp. individuals were peaked in the third
week of September, 2003 and in the last week of August, 2004. A. gossypil was the
most abundant pest species, followed by B. tabaci and Empoasca spp. Ants and
Chiysoperla camea were the most abundant predators, associated with the major
insect pests attacking okra plants. Generally, the present study showed that, the
natural role of the biocontrol agents in okra fields must be enhanced and developed.
Also, it revealed that, the three predators; C. camea, Scymnus spp. and Coccinella
undecimpunctata, could have a promising role when planning Integrated Pest
Management (1.P.M.) strategies, with other safe methods, to protect the surrounding
environment from pollution.
