A study on the bruchid, Callosobruchus chinensis (Linnaeus) : life cycle on Mung bean

Abstract

In life cycle study the average durations of pre-oviposition (6.49 ± 0.82 h), oviposition (6.53 ± 0.73 days), and post-oviposition (2.65 ± 0.41 days) were determined. The incubation period was 3.64 ± 0.78 days. Total grub period and pupal period were 14.43 ± 2.97 days and 5.25 ± 0.93 days, respectively. The average lifespan of male adult and female adult were 6.11 ± 0.64 days and 9.26 ± 0.69 days, respectively. The fecundity was 87.58 ± 8.03 eggs which ranged between 76 – 110 eggs/female. Total life cycle was completed in 26 – 39 days with an average duration of 29.43 ± 1.84 days in case of male while 28 – 41 days with an average duration of 32.58 ± 1.89 days in female. © (2023), (Malhotra Publishing House).
