Comparative flight behavior of Diabrotica virgifera virgifera and Diabrotica barberi in the laboratory
A tethered flight system was used to characterize and compare the flight behavior of western, Diabrotica virgfera virgfera LeConte (WCR), and northern, Diabrotica barber! (Smith and Lawrence) (NCR), corn rootworms in the laboratory. Distributions of flight durations were skewed towards short flights for both species regardless of sex or age and there was high variability in flight durations and...
متن کاملDiabrotica virgifera virgifera (Coleoptera: Chrysomelidae) larval feeding behavior on transgenic maize (MON 863) and its isoline.
Diabrotica species (Coleoptera: Chrysomelidae) larval behavior studies have posed a challenge to researchers because of the subterranean life cycle of this pest. To fully understand how the western corn rootworm, Diabrotica virgifera virgifera LeConte, injures the maize, Zea mays L., root system, its behavior must be studied. For example, larvae that can detect an area of the root that has a lo...
متن کاملGenes, Gene Flow and Adaptation of Diabrotica virgifera virgifera
1 Diabrotica virgifera virgifera has emerged as a major pest of cultivated maize, due to a combination of its high capacity to inflict economic damage, adaptability to pest management techniques and invasiveness. 2 This review presents a survey of the current state of knowledge about the genetics of D. v. virgifera . In addition, the tools and resources currently available to Diabrotica genetic...
متن کاملLikelihood of multiple mating in Diabrotica virgifera virgifera (Coleoptera: Chrysomelidae).
We evaluated the mating ability of male western corn rootworms, Diabrotica virgifera virgifera Leconte (Coleoptera: Chrysomelidae), for 20 d after initial mating, using a series of laboratory experiments. Males mated an average of 2.24 times within 10 d after their first mating and averaged 0.15 matings between days 11 and 20 after their first mating. Because estimating the mating frequency in ...
