Název v původním jazyce

The haemagglutination activity in the different developmental stages and changes of this activity caused by analogues of insect hormones in two members of the Culex pipiens complex of mosquitoes

Popis výsledku v původním jazyce

Haemagglutination activity (HA) was studied in larvae of the last larval instar, pupae, and adults of both sexes of the Culex pipiens mosquito complex. HA was detected in the females of anautogenous C.p.quinquefasciatus Say (before and after sucking water, glucose solution or blood), and in C.p.molestus Forskal. Our results show that HA in females not depends on the sucking of blood, but on the age of the females. In young females the level of HA was very low. After 24 or 48 hours HA was highly enhanced, even in females that had no possibility to suck water or other liquids including blood. It was concluded that HA in the gut of C.p.quinquefasciatus is not correlated with blood sucking behaviour. The possibility that HA activity may depend on some digestive enzymes system without any direct connection to blood uptake has been discussed. In addition, HA may be important not only for the elimination of infections but also for the processing of food utilisation and transport of nutrients.
