Natural Entomophages of Brevicoryne Brassicae (L.) (Hemiptera: Aphididae) in Uzbekistan

International Journal of Biology, 2019
In our studies phenological phases of cabbage aphids Brevicoryne brassicae (L.) were studied. The influence of external factors (humidity and temperature) was studied under laboratory conditions. The maximum reproductive ability of cabbage aphids was noted in spring and autumn. Some of the parthenogenetic aphids gave about 82 larvae.
