dc.description.abstractABSTRACT The present investigations entitled “Studies on life fertility table of diamondback moth, Plutella xylostella, (L.) (Lepidoptera) on different hosts” were carried out under laboratory conditions in the Department of Entomology, Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan (HP). The effect of three hosts viz. cauliflower, broccoli and mustard on biology and life fertility of P. xylostella was studied. Biological studies revealed that the maximum incubation period of 3.56 days was recorded on mustard followed by cauliflower (3.04 days) and broccoli (3.01 days). The total larval period was shortest on cauliflower (9.08 days) and longest on mustard (11.86 days). The total Fecundity was highest on cauliflower (253.36 females) followed by mustard (245.48 females) and minimum fecundity was observed on broccoli (182.72 females). Adults fed on cauliflower and broccoli lived longer than mustard. The Intrinsic rate of increase (rm) and finite rate of increase (λ) were highest on cauliflower (0.1730 females/female/day and 1.18 females/day, respectively) as compared to broccoli and mustard. The highest value of gross reproductive rate (GRR) and net reproductive rates (R0) (126.68 female eggs/female and 33.36 female eggs/female, respectively) were found when the pest was reared on cauliflower as compared to other hosts. The studies thus revealed that among the three hosts, cauliflower was the most suitable host for this pest.en_US
