Abstract

The effect of some insecticides on survival of the spider Parasteatoda tepidariorum Koch has been investigated under constant laboratory conditions 25±1°C and 70±5%RH. Mortality after 48h of treatment with LC50 of Abtar® 90%SP, Andros® 7.5%WG and Grand® 5%EC has been examined. The effectiveness of selected insecticides on the biological aspects such as longevity periods, prey consumption of adults and fecundity of females has been investigated. As well Andros® showed to be the most effective due to its high acute toxicity, on biological aspects for both female and male and prey consumption.  In addition, the study revealed that Andros® was also to be the most drastically effective on fecundity of females.
