Hemant Swami, Chetan Kalahal, Lekha and Deepak Jain

The investigation on biology of Rangeeni strain of lac insect on pigeonpea was carried out in the lac insect gene bank cum garden situated at Department of Entomology, Rajasthan College of Agriculture, MPUAT, Udaipur during Katki season 2016 with an aim to study the biological parameters viz., duration of pre-sexual stages (days), duration of male emergence (days), sex ratio (per cent male insect) and life period of female lac insect (days) on pigeonpea. The mean duration of pre-sexual stages lasts 48.36 days from the inoculation of broodlac with 11.50 days mean duration of male emergence and 11.33, 7.33, 4.02; 17.75, 10.63, 6.23 and 17.75, 11.73, 11.56 per cent male in lower, middle and upper portion of plant in three plots respectively.
