Size-dependent feeding and reproduction by boll weevil (Coleoptera: Curculionidae).
The considerable variation in adult size of the boll weevil, Anthonomus grandis grandis Boheman, has been well documented, but the influences of adult size on reproductive rate are not known. We examined the relationship between the size of boll weevils and their feeding and oviposition. Weevils weighed to the nearest milligram were grouped into five categories based on pupal weight: < or =5, 6...
متن کاملFlight ability and reproductive development in newly-emerged pine weevil Hylobius abietis and the potential effects of climate change
1 Adult pine weevils Hylobius abietis emerge from conifer root-stumps, on which larvae develop, over an extended period during summer and autumn. Newly-emerged weevils were tested for their ability to fly and assessed for wing muscle and reproductive development. In addition, the effect of summer–autumn maturation feeding on reproductive development was assessed in field bioassays. 2 There was ...
متن کاملCompetition and intraguild predation between the braconid parasitoid Bracon hylobii and the entomopathogenic nematode Heterorhabditis downesi, natural enemies of the large pine weevil, Hylobius abietis.
In biological control programmes introduced natural enemies compete with indigenous enemies for hosts and may also engage in intraguild predation when two species competing for the same prey attack and consume one another. The large pine weevil, Hylobius abietis L. (Coleoptera: Curculionidae), is an important pest of coniferous reforestation in Europe. Among its natural enemies, the parasitoid ...
متن کاملExperimental analysis of the mating system of the white pine weevil, Pissodes strobi (Peck) (Coleoptera: Curculionidae)
The white pine weevil, Pissodes strobi, severely restricts the growth and range of Sitka spruce (Picea sitchensis) in British Columbia. Knowledge of the patterns of male and female mating success is important for designing biocontrol programs and for understanding the reproductive potential of this weevil. To examine patterns of male and female reproductive success, we performed experiments in ...
متن کاملPiperidine alkaloids in sitka spruce with varying levels of resistance to white pine weevil (Coleoptera: Curculionidae).
Our objective was to evaluate piperidine alkaloids as potential resistance factors in Sitka spruce, Picea sitchensis (Bong.) Carr, at risk to attack by white pine weevils, Pissodes strobi (Peck). We sampled 72 seedlings in each of two replicated field trials in the Oregon Coast Range. The seedlings were grown from open-pollinated seeds of putatively "resistant" or "susceptible" off-site parenta...
