The social environment affects mate guarding behavior in Japanese beetles, Popillia japonica
The effect of the social environment on post-copulatory mate guarding duration in Japanese beetles, (Popillia japonica Newman), was examined in a laboratory experiment. The mate guarding durations of beetles in different sex ratios and densities were observed for 10 hours. Guarding duration was longer when females were larger, suggesting the presence of 'cryptic' male mate choice. Densities, bu...
متن کاملTranscriptional profiling reveals elevated CO2 and elevated O3 alter resistance of soybean (Glycine max) to Japanese beetles (Popillia japonica).
The accumulation of CO2 and O3 in the troposphere alters phytochemistry which in turn influences the interactions between plants and insects. Using microarray analysis of field-grown soybean (Glycine max), we found that the number of transcripts in the leaves affected by herbivory by Japanese beetles (Popillia japonica) was greater when plants were grown under elevated CO2, elevated O3 and the ...
متن کاملPhysical Contests for Females in the Japanese Beetle, Popillia japonica
Abstract We conducted field observations of physical competition for mates, in which a single male attempts to usurp a female from another male, in male Japanese beetles, Popillia japonica Newman (Coleoptera; Scarabaeidae). Physical contests for mates were relatively rare, but when they occurred the challenger male was able to successfully takeover females by dislodging the previously paired re...
متن کاملCytochrome Oxidase Activity during Diapause and Metamorphosis of the Japanese Beetle (popillia Japonica Newman)
1. Determinations were made on the activity of cytochrome oxidase of individual Japanese beetles during growth, diapause, and metamorphosis. All readings were made on homogenates at a dilution of 1:1,000, except for adult beetles, when the final dilution was 1:10,000. 2. The activity of the enzyme increased during larval growth from a low value of 0.022 in the second instar, to high values rang...
متن کاملLongevity and fecundity of Japanese beetle (Popillia japonica) on foliage grown under elevated carbon dioxide.
Atmospheric levels of carbon dioxide (CO(2)) have been increasing steadily over the last century. Plants grown under elevated CO(2) experience physiological changes that influence their suitability as food. Previous studies have found increased insect herbivory on plants grown under elevated CO(2). To determine effects of consuming foliage of soybean (Glycine max) grown under elevated CO(2) on ...
