Host-selection of Utethesia pulchella Linn. (Lep., Arctiidae)

Suitability of parts of food plant for Utethesia pulchella Linn. (Lep., Arctiidae)

“…(Lepidoptera : Arctiidae), a phytophagous insect, feeds and grows on Crotalaria juncea LINN. (LAL, 1917), Heliotropium indica (LAL, 1917) Crotalaria burhia (PANDEY et al, 1971), Crotalaria mysorensis ROTH and Melilotus indica (PANDEY and CHATTORAJ, 1973). The present author and CHATTORAJ (1974) have reared this insect on leaves of a foresaid host plants except Crotalaria burhia separately and have investigated the factors under lying the host-selection of this insect.…”

“…The present author and CHATTORAJ (1974) have reared this insect on leaves of a foresaid host plants except Crotalaria burhia separately and have investigated the factors under lying the host-selection of this insect. SRIVASTAVA and AWASTHI (1961) have briefly described the life cycle of this insect and have reported that in earlier stages of crop of Crotalaria juncea, the main host plant (PANDEY and CHATTORAJ, 1974), the caterpillars feed on foliage and in later stages they bore into pods and feed on seeds theirin. Recently in middle of September, 1974, the author has observed Caterpillars of this insect feeding on buds and flowers of Crotalaria juncea in the field.…”

Effect of Different Varieties of Gram on Growth, Development and Reproduction of Heliothis armigera (Hübner) (Lepidoptera: Noctuidae)

“…Among these, gram is the most preferred host of this species and, consequently, its yield is niuch retarded. Different food plants have been reported to exert influence on population-build in pests by affecting their growth, development and reproduction differently ( PANDE et al 1968;PANDEY & CHATTORAJ 1974;PANDE 1975PANDE , 1976PANDE , 1977YADAV et al 1978;LAL & MUKHERJI 1978;SRIVASTAVA Sr PANDE 1979;TRIPATHI & AKHTAR 1985). However, the influence of different varieties of gram on growth, development and reproduction of this pest is yet to be screened.…”
