520 _aThe toxic effect of Challenger (36% SCl and Vapcomic (1.8% ES) on the two spotted spider mite Tetranychus cucurbitacearum (Sayed) was studied Wlder laboratory conditions. Results indicated that Vapcomic was the more toxic compoWld, where the LCso value was 0.54 ppm, while Challenger was less and toxicant, the LCso value was 10.0 ppm. The influence of LCso concentration of the two tested compoWlds on some biological aspects of T. cucurbitacearum was evaluated Wlder laboratory conditions. The two tested 1:0mp.oWlds had the ability to elongate the pre-oviposition peried while they were able to decrease the oviposition, post-oviposition period and the adult female longevity. Also, the average number of deposited eggs per female decreased from 51.8 to 12.6 and 3.6 eggs layed/female for Challenger and Vapcomic, respectively. Hatchability of mite's eggs decreased being 57.62% with Challenger and 76.47% with Vapcomic. Total mortalities of mite immatures were 61.66% lIRd 45.17% in Challenger and Vapcomic, respectively. On the other hand, the duration of immature stages and total life cycle of this mite were prolonged when adult females were treated with (LCso) of two tested compoWlds compared with Wltreated ones.
