Age-stage, two-sex life table of the tomato looper, Chrysodeixis chalcites (Lepidoptera: Noctuidae), on different bean cultivars
Arthropod-Plant Interactions 8 (5), 475-484
Abstract: The tomato looper, Chrysodeixis chalcites (Esper), is one of the polyphagous pests of several economically crops worldwide. Two-sex life table parameters of C. chalcites reared on eight bean cultivars including white kidney bean (cultivars Daneshkadeh and Dehghan), red kidney bean (cultivars Goli and Naz), common bean (cultivars Khomein, Talash and Sadra) and cowpea (cultivar Mashhad) were studied under laboratory conditions (25 ± 1 °C, 65 ± 5 % RH, a 16:8-h light–dark photoperiod). The shortest larval period of C. chalcites was 14.15 days on common bean Sadra. The longest and shortest development time of total preadult was on white kidney bean Daneshkadeh and common bean Sadra (25.77 and 23.42 days, respectively). The highest total fecundity was on common bean Sadra (674.4 eggs), and the lowest was observed on white kidney bean Daneshkadeh (136.7 eggs). The intrinsic rate of increase (r_m ) ranged from 0.0976 to 0.1599 female/female/day, which was lowest on white kidney bean Daneshkadeh and highest on common bean Sadra. The net reproductive rate (R₀) was highest on common bean Sadra (265.82 offspring) and lowest on white kidney bean Daneshkadeh (46.88 offspring). The results revealed that the cultivar Daneshkadeh was unsuitable host to C. chalcites in comparison to the other cultivars tested.
