“…However, Nakamura and Noda (2002) reported nonsignificant difference in sex ratio among host sizes in O. sokolowski. In the present investigation, the results on sex ratio of N. thymus, when developed on M. domestica of different sizes, conform those recorded by Charnov et al (1981), Bovida et al (1995), King (1987King ( , 1988King ( , 1993, Visser and van Alphen (1987), Heinz and Parrella (1990), Islam (1995), Nechols and Kikuchi (1985), Wen et al (1995), Omwega and Overholt (1997), Ueno and Tanaka (1997) and Ueno (1998).…”

An investigation was conducted to understand the influence of host size on the reproductive performance of Nesolynx thymus, an ecto-pupal parasitoid of the uzi fly, Exorista bombycis, inflicting 10-20% loss to silkworm crops in the southern silk producing states of India. Two day-old adults of N. thymus were allowed to parasitize pupae of M. domestica, categorized into big and small at a parasitoid-host ratio of 1:20. After parasitoid adult eclosion, data on parasitization rate, developmental duration, male, female and total adult recovery per pupa and per female, sex ratio, adult size and adult longevity were recorded. The performance of first generation adults as influenced by host size was also recorded by allowing the first generation adults to parasitize three day-old pupae of E. bombycis. The parameters female and total progeny production per female, sex ratio, longevity, body length and wing span of males, females, head width of male, and abdomen length of female increased significantly with host size. No impact of host size was observed on performance of first generation adults.

“…The female parasitoids when developing from 4th instar C. chinensis larvae were bigger. Host-age significantly affected the offspring production in D. basalis on C. chinensis (Islam, 1995b). The offspring production was in the order 4th instar larvae> pre-pupae> pupae> 3rd instar larvae> 2nd instar larvae.…”

“…D. basalis lays eggs on the surface of mature larvae, pre-pupae and pupae of C. chinensis and oviposition period lasts for about 21 minutes. The biology of D. basalis at 30±1EC and 70 percent rh has been given by Islam (1995a). The deposited egg is typically hymenopteriform, dirty white, smooth, elongate and rounded at both ends.…”

“…Superparasitism did not affect the duration of developmental periods and size of adults but the percentage of female progeny was somewhat reduced at higher parasitoid densities. Islam and Kabir (1992) gave an account of the mass culture and production of D. basalis on C. chinensis. The total number of F 1 offspring produced from 1000 parasitoids was 30,627 in a week.…”

Abstract:The use of chemical pesticides against storage pests by farmers in developing countries like Bangladesh is inadequately docummented. The holistic view of pest control technology is required to evaluate its impact on net social welfare, the simultaneous determination of optimal storage operations, consumption and production over time and optimal pest management. To make these variables operational the collaboration of biologists (especially pest management expert), economists, systems analysts, extension workers and social scientists are very much to be solicited. It is apparent that our basic understanding of bruchid pests is still far from being adequate. Therefore, intensive studies of their, biology, ecology and effects on foodstuffs are needed to be vigorously persued. Chemical pesticides are expected to play a major role in pest management programmes. However, the development of alternative pest management strategies involving non-chemical methods should vigorously pursued. There is no single answer to pest problems. The development of an integrated pest management system incorporating the principles, methods and techniques advanced by various disciplines into a coherent and comprehensive programme seems to be the answer.

“…The effectiveness of D. basalis in the biological control of C. maculatus, C. chinensis, and B. atrolineatus was demonstrated experimentally, but the success depends on the storage conditions (Islam & Kabir, 1995, Ouedraogo et al, 1996, Sanon et al, 1998.…”

Callosobruchus analis (F.) is considered an important pest in several countries in Africa, Asia and Oceania. It has been observed infesting seeds belonging to 15 Leguminosae genera, including peanut, bean, chickpea, pea, cowpea, and soybean. One of its main natural enemies is the parasitoid Dinarmus basalis (Rondani) (Hymenoptera: Pteromalidae), whose control efficiency has already been demonstrated in several studies. This paper records the occurrence of C. analis and its parasitoid, D. basalis, in stored soybean of the state of São Paulo, Brazil.
