"The aim of the project is to study the influence of insect hormones, their analogues and antagonists on development and fecundity of selected insect species. The mechanism of action of the above mentioned compounds will be studied in Spodoptera littoralis and Culex pipiens s.l.. In mosquitoes the influence of ecdysteroid antagonists and agonists on hematophagous behaviour will be studied in correlation with autogeny and anautogeny. In addition to the determination of the ecdysteroids level in the whole body and in the gonads, ultrastructure of the fat body as well as reproductive organs will be studied in relation to hematophagous behaviour. We expect the enrichment of the knowledge of the generally valid biological rules as well as obtaininga new informations useable for practical use in the pest control."@en . .
