Abstract
Mealybug lcetya seychellarum is considered one of the most im­portant economic insect of mulberry trees. This insect pest causes seri­ous problems to silk industry in Egypt. So, the present study is an at­tempet to test two local mineral oils (IQ-oil and CAPL-2) against this insect with Arimitsu sprayer compared with one of the recommended in­secticides (Cidial), with two application rates 420,630 lit,/ fed. Biologi­cal date revealed that, application rate 420 lit./fed. of Cidial insecticide with pnuematic-rotary-atomization induced sufficient control against this insect. Droplet spectrum of deposited spraying with 420 lit./fed. were 158 spots/Cm2 having an average diameter (VMD) of 94 microm­eter (pm). Next comes KZ-oil at the lower rate of application 420 lit./ fed. and droplet spectrum of deposited spraying was 138 spots/Cm2 having an average diameter of 103 pm. The lowest biological activity treatment resulted from CAPL-2 at the same rate of application. The droplet spectrum of deposited spray 143 spots/Cm2 having VMD of 99 pm. The best control result (90.8%) was achieved by Cidial insecti­cide using flow rate 420 lit./fed. higher rate of application (630 lit./ fed.) gave the next level of control result (77.2%) followed by KZ-oil which gave 76.5%, 72.1% reduction using lower and higher rates of ap­plication (420 lit./fed., 630 lit./led.), respectively. Similar trend was found with CAPL-2 where 69.6% and 63.8% were achieved by applying 420 lit./fed. and 630 lit./fed. successively.
