Abstract/Contents:Discusses the "voltinism of Gryllotalpa africana ... on turfgrass in South Africa." States that G. africana (African mole cricket) was flushed from infested kikuyu grass using soapy water and "counted and measured from the posterior of the abdomen (excluding cerci) to the distal end of the labrum" to determine the life cycle. Profiles the cricket's life cycle. Results show that "the mean monthly length of sampled nymphs and the total population showed a relative decline during the winter and may have reflected a tendency of younger (and shorter) adults and nymphs to stay active [as] long as possible to attain a larger size (longer length) to increase their fitness during the following spring reproductive period. Larger males of Scapteriscus produce louder calls and attract more females, whilst larger Scapteriscus females produce three times more offspring and 1.5 times as many eggs per clutch than smaller females."
Geographic Terms:South Africa
