ThesisItem Open Access Effect of cold storage on some biological characteristics of parasitoid, Aenasius bambawalei Hayat (Hymenoptera: Encyrtidae)(CCSHAU, 2014) Rathee, Mandeep; Pala RamThe present studies on cold storage and overwintering of Aenasius bamabawalei were carried out during 2012-13 both in the laboratory as well as in the screen house of the Department of Entomology, CCS Haryana Agricultural University, Hisar to generate information on effect of cold storage of the parasitoid, A. bambawalei in different stages for different durations at different temperatures on its biological parameters and to evaluate the survival of the parasitoid during winter season. Studies on cold storage of the parasitoid were carried out by storing one-day-old Phenacoccus solenopsis mummies (i.e. in pupal stage) and freshly emerged adults at four storage temperatures i.e. 5, 10, 15 and 20°C for 1 to 8 weeks. It was found that the parasitoid A. bambawalei can be stored in pupal stage (i.e. in the mummies of P. solenopsis) for 1 week at 5°C and for 2 weeks each at 10 and 15°C, respectively, without any significant effect on the key biological parameters like emergence, longevity, fecundity and sex-ratio (F1 progeny). Emergence of the adults occurred within first week during storage at 20°C, hence, this temperature was not suitable for storing the parasitoid in pupal stage. Females took more time to emerge from the mummies stored for different durations at 5, 10 and 15°C as compared to males. The parasitoid adults of A. bambawalei can be stored only for 1 week at 10°C without any significant affect on the key biological parameters like survival, longevity, fecundity and sex-ratio (F1 progeny). The parasitoid A. bambawalei can be stored at low temperatures both in pupal and adult stages. However, it can be stored safely for longer duration in pupal stage as compared to adult stage. Emergence of parasitoid adults from overwintering mummies started from 11th standard week (first week of February), being maximum in 14th standard week (first week of March) and continued until 16th standard week (third week of March) when all the parasitoid adults had emerged. Maximum temperature ranged between 20.3 to 29.6oC and minimum between 6.6 to 12.5°C during the period of adult emergence. Honey fed parasitoid adults i.e. males survived for 52-84 days (69.33 days) and females survived for 69-103 days (83.40 days) during winter season in absence of host, when exposed on 5th December. The results of the present studies may be helpful in mass rearing and conservation of the parasitoid.ThesisItem Open Access Stqdies on population dynamics of jassid, spotted and pink bollworms of cotton(College of Animal Sciences Chaudhary Charan Singh Haryana Agricultural University Hisar, 1985) Kumar, Raj; Naresh, J.
