چکیده

We conÞrmed that commercial threeor four-component Spodoptera frugiperda (J.E. Smith) pheromone lures had a high nontarget capture rate for Leucania phragmatidicola Guenée, which compromised monitoring efforts in the northeastern United States. We compiled taxonomic features to distinguish L. phragmatidicola from S. frugiperda, and we compared Þve new lures. S. frugiperda catch speciÞcity was improved by removing (Z)-11-hexadecen-1-ol acetate (Z11Ð16:Ac), which attracted L. phragmatidicola. Four lures tracked late-season S. frugiperda immigration, but two of these lures also tracked a bivoltine L. phragmatidicola ßight with a second generation coincident with S. frugiperda immigration, and one lure attracted the Þrst, but not the second, generation of L. phragmatidicola. In both lowand high-moth ßight conditions, two-component lures had low L. phragmatidicola captures (0.5Ð1.4%), and although lureswithmorepheromonal components captured more S. frugiperda, they also had a high percentage of capture of L. phragmatidicola (38Ð48%). We conclude that although two-component lures captured fewer S. frugiperda, their similar temporal pattern, along with the lower level of L. phragmatidicola, makes them useful for development for monitoring programs in the northeastern United States.

Several restriction sites in the cytochrome oxidase I gene of fall armyworm, Spodoptera frugiperda (J.E.

Strain speciÞcity was demonstrated for populations in Florida, Texas, Mississippi, Georgia, and North Carolina, with an AciI and SacI site speciÞc to the rice (Oryza spp.)-strain and a Bs...

Evolutionary Ecology of Pheromone Signaling in Dendroctonus frontalis

Although studies of pheromone production in the southern pine beetle (Dendroctonus frontalis) extend back to the dawn of chemical ecology, it is only recently that instrumentation has become sufficiently sensitive to measure pheromone production of individual beetles. Now, recent studies have revealed surprisingly high variation among individuals in their pheromone production. This seems parado...

Risk and Nonindigenous Species Management ∗

S nonindigenous species threaten people by contributing to biodiversity loss and environmental damage (Elton; Kareiva). Managing such threats cost-effectively requires a consistent framework that captures the biological and economic circumstances that jointly determine the level of risk and the optimal mix of prevention and control strategies. The economic theory of endogenous risk provides suc...

Dispersal of Rhyzopertha dominica (Coleoptera: Bostrichidae) in different habitats.

The lesser grain borer, Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae), a serious pest of stored cereal grains, is widely distributed and has been collected in different habitats in North America, such as those from agricultural and nonagricultural settings. Our objective was to study the dispersal distances and direction of dispersal by R. dominica after external marking using fluorescen...
