Virulence of entomopathogenic nematodes to pecan weevil larvae, Curculio caryae (Coleoptera: Curculionidae), in the laboratory.
The pecan weevil, Curculio caryae (Horn), is a key pest of pecans in the Southeast. Entomopathogenic nematodes have been shown to be pathogenic toward the larval stage of this pest. Before this research, only three species of nematodes had been tested against pecan weevil larvae. In this study, the virulence of the following nine species and 15 strains of nematodes toward fourth-instar pecan we...
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 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 ...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Effect of Paecilomyces Lilacinus Strain 251 on the Survival and Virulence of Entomopathogenic Nematodes under Laboratory Conditions
maceae) is a nematophagous fungus that has been shown to be effective against a wide spectrum of plantparasitic nematodes (Rumbos and Kiewnick, 2006). The commercial strain 251 (PL251) has recently received US registration as a biological nematicide under the trade name MeloCon WG, whereas it is undergoing registration procedure as BioAct WG in Europe (Kiewnick and Sikora, 2006). Entomopathog...
