The present study was carried out during 2014 and 2015 growing seasons of cantaloupe.

Faunistic composition of pests and their associated predators inhabiting cantaloupe plants Cucumis melo L.

revealed the presence of 22 insect species belonging to 17 families and 10 orders.

The serious pest species were represented by 14 species with 7 predaceous species.

The most abundant sucking insect pest was whitefly ; Bemisia tabaci Genn.

It was the most abundant and seemed to be the major pest infesting cantaloupe, followed by the two spotted spider mite, Tetranychus urticae Koch.

and some piercing sucking insects such as cotton aphids, Aphis gossypii Glov.; onion thrips, Thrips tabaci Lind.

and jassids, mpoasca spp.

Orius sp, Chrysoperla carnea Steph.

and Coccinella undecimpunctata L.

were the most numerous predators.

In all cases the dominance degrees of the pests were higher than those of the predators.
