Abstract:
The present investigation on “Comparative studies of productivity linked parameters of Lac insect, Kerria lacca on different lac hosts prevailing in Southern Rajasthan” was conducted on Rangeeni strain of lac insect in Baisakhi season at Department of Entomology, Rajasthan College of Agriculture, MPUAT, Udaipur during 2020-21. The present investigation was carried out by ex situ inoculation of brood lac on various hosts viz., Custard apple, Ber, Palas, Babool, Kikar, Flemingia macrophylla and Flemingia semialata. Among which Ber found to be most effective, preferred and superior host compared to other host. Initial, final settlement and mature female cell density recorded was 116.50, 106.03 crawlers and 4.93 cells per sq.cm, respectively; while, per cent settlement and per cent mortality was 90.55% and 8.84%. Which is followed by Babool, Palas, Custard apple, Flemingia macrophylla and Kikar. While the least effective and preferred host was Flemingia semialata in which initial, final settlement and mature female cell density recorded was 64.87, 54.70 crawlers and 2.80 cells per sq.cm, respectively with 83.56 per cent settlement and 15.64 per cent mortality.
