	abstract = {The effect of adult learning through an oviposition and host feeding experience was studied in two populations of Anisopteromalus calandrae (Hymenoptera: Pteromalidae), in choice and no-choice experiments in the laboratory using last instars of rice weevil, Sitophilus oryzae L., and lesser grain borer, Rhyzopertha dominica (F.), as hosts. In choice experiments, 20 wheat kernels infested by rice weevil and 20 by lesser grain borer were placed randomly in petri dish (15 by 100 mm) arenas. In no-choice experiments, 10 host-infested wheat kernels, either with rice weevils or with lesser grain borers, were mixed thoroughly in 500 g of uninfested wheat placed in a 0.945-liter glass jar (75 by 170 mm) arenas. A. calandrae females from a laboratory and field populations that were experienced with host larvae or naive were introduced singly into each experimental arena and allowed to sting and oviposit for 24 h. An oviposition experience with rice weevil or lesser grain borer had a stronger effect on host preference in choice experiments compared with experiments with naive wasps. Host-finding and parasitism rates were increased by prior experience with rice weevils in no-choice experiments. A. calandrae females clearly preferred rice weevil larvae for parasitization over larvae of lesser grain borer regardless of parasitoid population or prior experience. Also, A. calandrae females chose rice weevil larvae for producing female progeny and lesser grain borer for male progeny in choice experiments. The implications of the results of this study are discussed in relation to host preference and the selection of parasitoid populations for biological control programs in stored grains.},

	abstract = {We investigated the ability of two populations of Anisopteromalus calandrae (Hymenoptera: Pteromalidae), to parasitize and develop on late instars of five different stored-product insects that typically complete their development inside seeds of grain or legume species or other dry commodity. The host species were the cigarette beetle, Lasioderma serricorne (F.); cowpea weevil, Callosobruchus maculatus (F.); rice weevil, Sitophilus oryzae (L.); lesser grain borer, Rhyzopertha dominica (F.); and Angoumois grain moth, Sitotroga cerealella (Olivier). Experiments were conducted in the laboratory in a no-choice design by using petri dishes (15 by 100 mm) as experimental arenas with 20 host larvae. A. calandrae females from populations originating in Georgia (GA) and Oklahoma (OK) were introduced singly into experimental arenas and allowed to sting and oviposit for 24 h. Parasitism by the OK population was greater than that for the GA population across all hosts. However, no or very low parasitism was found on Angoumois grain moth for either population in this experiment. The highest number of parasitoid progeny was recorded on cowpea weevil (15.9) followed by rice weevil (11.5) and cigarette beetle (10.8) for the OK population. A similar trend was observed in the GA population. The highest proportion of female progeny was produced on cowpea weevil (73.0\%) by the OK population. Conversely, a higher proportion of female progeny was produced on rice weevil (64.6\%) by the GA population than produced by the OK population. Parasitoid adults were significantly larger and heavier when they developed on cowpea weevil irrespective of parasitoid population. The possible application of these results for biological control of stored-product insects is discussed.},

	abstract = {Feeding male Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae) produces two pheromones Dominicalure-1 (DL-1) and Dominicalure-2 (DL-2), which attracts adults of both sexes. In field experiments conducted in Oklahoma, R. dominica captures in multiple funnel traps deployed with its pheromones, ethanol, or both, green-leaf volatiles (GLV), plant essential oils, or synthetic pheromones for Ips spp., Dendroctonus spp., or Scolytus multistriatus (Marsham) (Coleoptera: Scolytidae) were examined. The bark beetle lures were evaluated at the release rate recommended for the respective insects. The number of insects trapped increased when R. dominica lure was combined with ethanol, whereas beetle captures neither were enhanced nor inhibited when the lure was combined with GLV, 3-methylcyclohex-2-en-l-one (MCH), or plant essential oil mixtures turpentine, from Pinus spp., and cedar wood oil, from Juniperus spp. (Coniferales: Pinaceae and Cupressaceae). Similarly, the numbers of captured R. dominica did not significantly differ when R. dominica lures were supplemented with ipsdienol, ipsenol, cis-verbenol, or pityol. Conversely, the combination of R. dominica lures with exo-brevicomin, frontalin, and commercial lure for S. multistriatus, containing the bicyclic ketal multistriatin, resulted in significantly fewer captures of R. dominica. The presence of live males of the closely related species Prostephanus truncatus (Horn) decreased the number of captured R. dominica by >70\% compared with captures in traps baited with R. dominica{\textquoteright}s natural pheromone alone. Results support the hypothesis that grain-infesting R. dominica evolved from forest-inhabiting ancestors and retained behavioral traits for semiochemical interactions with other wood-boring beetle species. Such interspecific interactions have potential for exploitation in pest management programs against R. dominica.},
