Effects of Cypermethrin on Total Body Weight, Glyco- gen, Protein, and Lipid Contents of Pimpla turionellae (L.) (Hymenoptera : Ichneumonidae)

چکیده
We investigated the changes in total body weight, glycogen, protein, and lipid contents of the endoparasitoid Pimpla turionellae L. (Hymenoptera : Ichneumonidae) reared on Galleria mellonella L. (Lepidoptera : Pyralidae) exposed to various sublethal doses of cypermethrin added to the food of host larvae. Cypermethrin affected the total body weight of larvae, pupae, and adult females but not males. Results revealed that the levels of glycogen, protein, and lipid in all stages and sexes of the wasp tended to decline with respect to controls. Females showed the most striking decrease in glycogen content whereas larvae were more susceptible to cypermethrin than pupae and adults in terms of decrease in protein and lipid contents.

The variation of the amount of the neurosecretory materials in the Corpus Allatum of Pimpla turionellae L. (Hymenoptera: ichneumonidae) during oocyte maturation.
The purpose of this study is to examine the effects of neurosecretory material (NSM) in Corpus Allatum (CA) of endoparasitic Pimpla turionellae L. on reproduction. For this purpose, the egg maturation of the insect and the amount of the NSM in CA of the serial section of the brain were studied. Egg maturation was determined by measuring the terminal oocyte length. In order to determine the amou...

Correct species identification is the basis of ecological studies. Nevertheless, morphological examination alone may not be enough to tell species apart. Here, our integrated molecular and morphological studies demonstrate that the relatively widespread and common neotropical parasitoid wasp Pimpla croceipes Cresson, 1874 (Hymenoptera: Ichneumonidae: Pimplinae) actually consists of two distinct...
