Insect biodiversity in cauliflower and biology of cabbage white butterfly, Pieris brassicae (L.)

Insect species complex of cauliflower and biology of Pieris brassicae (L.) were studied during 2013–2014 in the Department of Life Sciences, Manipur University. The study revealed twenty five species of insects comprising of 16 pests and 8 predators (4 coccinellids, 3 syrphids and one crambid). The biology of Pieris brassicae (L.) on cauliflower revealed that the egg period was 3.00±0.00 and 4.0±0.00 days during October-December and January-April respectively. The entire life cycle (egg to adult) occupied 50.22±1.56 days and 60.76±1.71 days during the two seasons studied.
