| 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- | ||
