| development of a bioassay system for the predator, xylocoris flavipes (heteroptera: anthocoridae), and its use in subchronic toxicity/pathogenicity studies of beauveria bassiana strain gha. | microbial biocontrol agents are useful commercially only if they do not harm other natural biocontrol organisms, at recommended use rate in the environment where the microorganism is being used. to test the hypothesis that the predatory warehouse pirate bug, xylocoris flavipes (reuter), is not adversely affected by the entomopathogen, beauveria bassiana (balsamo) vuillemin strain gha, we developed a method using individually confined bugs during a 10-d feeding regime. three concentrations of a c ... | 2003 | 14503574 |
| optimal xylocoris flavipes (reuter) (hemiptera: anthocoridae) density and time of introduction for suppression of bruchid progeny in stored legumes. | the influences of both predator density and elapsed time between initial infestation and introduction of predators were determined for suppression of bruchids infesting stored grain legumes by xylocoris flavipes (reuter) (hemiptera: anthocoridae). predator density treatments consisted of zero, one, two, three, or five male:female pairs of adult x. flavipes added to experimental arenas 0, 24, or 120 h after bruchid introduction. suppression of acanthoscelides obtectus approached eradication with ... | 2008 | 18348804 |
| storage insects on yam chips and their traditional management in northern benin. | twenty-five villages of northern benin were surveyed to identify the constraints of yam chips production, assess the diversity of storage insects on yam chips, and document farmers' perception of their impacts on the stocks and their traditional management practices. damages due to storage insects (63.9% of responses) and insufficiency of insect-resistant varieties (16.7% of responses) were the major constraints of yam chips production. twelve insect pest species were identified among which dino ... | 2013 | 23710140 |
| multiple mating in the traumatically inseminating warehouse pirate bug, xylocoris flavipes: effects on fecundity and longevity. | optimal mating frequencies differ between sexes as a consequence of the sexual differentiation of reproductive costs per mating, where mating is normally more costly to females than males. in mating systems where sexual reproduction is costly to females, sexual conflict may cause both direct (i.e. by reducing female fecundity or causing mortality) and indirect (i.e. increased risk of mortality, reduced offspring viability) reductions in lifetime reproductive success of females, which have indivi ... | 2012 | 22573833 |
| survival of stored-product insect natural enemies in spinosad-treated wheat. | the survival of stored product insect natural enemies in wheat treated with spinosad was investigated in laboratory and pilot scale experiments. the predator xylocoris flavipes (reuter), the warehouse pirate bug, and the parasitoids habrobracon hebetor (say), theocolax elegans (westwood), and anisopteromalus calandrae (howard) were exposed to wheat treated with aliquots of water or spinosad at 0.05-1 mg ([ai])/kg. x. flavipes was the only species that survived (92% survival) in spinosad-treated ... | 2004 | 15279307 |
