Reproductive Capacities and Development of a Seed Bruchid Beetle, Acanthoscelides macrophthalmus, a Potential Host for the Mass Rearing of the Parasitoid, Dinarmus basalis
The reproductive capacities and development of the seed beetle Acanthoscelides macrophthalmus (Schaeffer) (Coleoptera: Bruchidae), found in Togo, were determined under natural conditions in a Guinean zone for its use as a substitute host for the mass rearing of the parasitoid Dinarmus basalts Rond (Hymenoptera: Pteromalidae), a biological agent for the control of beetles that are pests of cowpe...
متن کاملFunctional Response of Dinarmus Basalis (rond.) (hymenoptera: Pteromalidae) Parasitizing Callosobruchus Maculatus (f.)
The functional response of the parasitoid Dinarmus basalis (Rond.) (Hymenoptera: Pteromalidae) is determined to evaluate its potential as a biological control agent. Four female wasps in the presence of males parasitoids, were allowed to oviposit during their life span or hosts at different densities. The data were fit by Rogers′ (1972) parasitoid model. The rate of parasitoid search was a′= 0....
متن کاملImpact of αAI-1 Expressed in Genetically Modified Cowpea on Zabrotes subfasciatus (Coleoptera: Chrysomelidae) and Its Parasitoid, Dinarmus basalis (Hymenoptera: Pteromalidae)
Genetically modified (GM) cowpea seeds expressing αAI-1, an α-amylase inhibitor from the common bean, have been shown to be immune against several bruchid species. Effective control of such pests by growing GM cowpea could promote the spread of bruchid species that are αAI-1 tolerant. Consequently, the sustainability of bruchid pest control could be increased by combining GM seeds and hymenopte...
متن کاملInfluence of Host Origin on Host Choice of the Parasitoid Dinarmus basalis: Does Upbringing Influence Choices Later in Life?
The aim of this study was to investigate the influence of volatile compounds from four secondary host plants on the ability of Dinarmus basalis Rond. (Hymenoptera: Pteromalidae) to locate, recognize, and parasitize its host, 4(th)instar larvae or pupae of Callosobruchus maculatus F. (Coleoptera: Chrysomelidae). To examine this, strains of D. basalis were transferred from cow-pea seeds (Vigna un...
متن کامل~YSIOLOGIG~L AND CHEMICAL ECOLOGY Attraction of the Bark Beetle Parasitoid Rop~rocews xylophugorum (Hymenoptera: Pteromalidae) to Host-Associated Olfactory Cues
Studies were conducted to identify host location cues used by Roptrocerus xylophagorum (Batzeburg), a larval/pupal parasitoid of bark beetles. In Y-tube olfactometer bioassays, female rylophagorum were attracted to infested bark (i.e., phloem, cambium, and outer corky bark tissues) removed from bolts of loblolly pine, Pinus tueda L., colonized by the late instar larvae and pupae of the bark bee...
