چکیده

Laboratory bioassays were carried out to evaluate the insecticidal efficacy of SilicoSec? against ۷ - ۱۴ day old adults, old and young larvae of Tribolium castaneum (Herbst) with the mean ? SE (n = ۳۰) weight of ۳.۴ ? ۰.۱ and ۰.۶ ? ۰.۱ mg, respectively at ۲۷?C and ۵۵ ? ۵% RH. Wheat treated with four dose rates of SilicoSec? and untreated wheat served as a control with three replications. Adult?s mortality was measured after ۲, ۷ and ۱۴ days of exposure. After ۱۴ day mortality counts, all adults were removed and samples retained under the same conditions for a further ۶۰ days to assess progeny production. In the case of larvae, mortality was counted after ۱, ۲ and ۷ day. After ۲ day no concentration achieved ۱۱% mortality for adults, however; adult's mortality exceeds ۸۹.۶۵% when exposed for ۷ day to SilicoSec?. Mortality of old and young larvae at ۶۰۰ ppm after ۲ day were ۲۸.۸۸ and ۲۲.۲۲%, respectively and exceed to ۶۰.۷۱ and ۶۹.۰۴% at longer exposure of ۷ day. Due to results mortality of T. castaneum was influenced by interval exposed to wheat treated with SilicoSec? and over this exposure, the increases in application rate of SilicoSec? had significant effect on the mortality. Young larvae of red flour beetle were more sensitive to SilicoSec? than old larvae and adults were more tolerant. The mean number ? SE of progeny in the control was ۱.۶۶ ? ۰.۱۰۱ individuals per vial and there was a significant difference between treated and untreated wheat, so reproductive potential of adults in treated wheat was suppressed when compared with untreated wheat.   REFERENCES  Abbott, W.S., (۱۹۲۵) A method of computing the effectiveness of an insecticide.
