Abstract

In Egypt and during the last ten years, the trend in the popula­tion density of the rosy wooly scarabeid Tropinota squalida Soap. (Family Scarabaeidae, Order Coleoptera) was multiplied and increased considera­bly to build up a serious and damaging level, causing reliable losses to apple trees. Several control methods were adopted for its control . This work was undertaken to evaluate mass trapping of adults depending on th re­sults obtained from new watery traps compared with the comonly used blue baisn trap. Field trials by both traps demonstrated the high efficien­cy of the watery trap which captured adults more than twice of the to­tal number of insects caputred by the blue one. The direct control of T. Squalida by mass trapping of adults, using proper numbers of water traps could reduce the population level of this insect below the econorn-
