A note on the effect of date of sowing on Heliothis armigera Hubner attack on pea (Pisum sativum L.)



A note on the effect of date of sowing on Heliothis armigera Hubner attack on pea (Pisum sativum L.)



Indian Journal of Entomology 50(4): 533-534



The effect of sowing date on the incidence of Heliothis armigera on pea was studied in Rajasthan, India, in 1981-82. Three different varieties were used, and 7 dates were tested. Minimum damage was recorded in Bournville with the 1st date of sowing (15 October 1981) and in T-163 and L-116 with the last date (27 November 1981). Maximum damage was recorded in L-116 with the 1st sowing date, T-163 with the 5th sowing date (13 November) and Bournville with the 3rd date (4 November).
