Abstract

The comb-footed spider, Anelosimus aulicus, has great potential to
suppress insect pests of agricultural crops. The effect of some insecticides
used against these pests on survival of this spider was investigated under
laboratory conditions. Mortality and changes in the fine structure of the
midgut 48h after treatment with Lannate®, Reldan® and Match® were
examined. The LC50's, LC90's and slope of these insecticides were given.
Lannate® was the most effective due to high acute toxicity, causing 66.7%
mortality in females and 91.6% in males. It was also the most drastically
effective on fecundity of females where no egg sacs were laid under the
recommended field concentration (0.3gm/ 200 ml water). Reldan® caused
58.3% mortality in females and 83.33% in males. The least effective was
in Match® causing 50% mortality in females and 58.33% in males.
Obviously, males were more affected than females. The effect of
insecticides on longevity periods and prey consumption of adults and,
fecundity of females, at different concentrations of insecticides, were
investigated. On the other hand, the histological study on the midgut
glands of adults using Transmission Electron Microscope revealed
similarity in structure of females and males of untreated spiders, whereas,
treated spiders showed different changes indicated by the absence of some
cells in the tissues in this organ, which might affect its digestive function
and therefore ability for survival.
