Mosquito eggs laid within two hours are necessary for transgenic (injection) studies, because mosquito eggs become hard after that period. Thus, in order to have eggs available within this two-hour window, it is important to understand the ovipositional behavior of Anopheles gambiae s.s.. In the present study, the ovipositional behavior of An. gambiae s.s. (Kisumu) was investigated in several d...

tion, two with the 4th, three with the 5th, and one with the 6th generation). The tests were done in a 15cm diameter Petri dish containing a layer of 1cm of pure agar (2g for 20ml of water) so the larvae could move. Nine 2cm circular holes, were opened in the agar eight being equally distant from the central hole (Fig.). We dropped melted agar in the newly opened holes, which after getting cold...

The larval stage of S. aphidophagous in nature, while the adults are efficient pollinators various crops. Therefore, this study was carried out to investigate predation efficacy, biology and population growth parameters on cabbage aphid, Brevicoryne brassicae (Hemiptera: Aphididae) as p...

Potential trap crops for the diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), were evaluated through a series of ovipositional preference and larval survival experiments in outdoor screenhouses in 2002 and 2003. Hosts examined as trap crops were glossy and waxy collards, Brassica oleracea L. variety acephala; Indian mustard, Brassica juncea (L.) Czern; and yellow rocket,Ba...
