Nectar-seeking and host-seeking by Larra bicolor (Hymenoptera: Crabronidae), a parasitoid of Scapteriscus mole crickets (Orthoptera: Gryllotalpidae).
Larra bicolor F. (Hymenoptera: Crabronidae) is a specialist parasitoid of Scapteriscus (Orthoptera: Gryllotalpidae) mole crickets, attacking adults and medium to large nymphs of the hosts. Adult wasps derive energy from plant nectars. In replicated trials in pastures in northern Florida, many more wasps fed on nectar of Spermacoce verticillata F. (Rubiaceae), a non-native plant, than on nectar ...
متن کاملPygmy mole crickets jump from water
to have spoken, but found at the last moment that he was too busy, and so sent Wilkins. Watson’s plan of using his sister as bait for the unattached Wilkins failed, and Wilkins rejected his overtures. Had Wilkins been more forthcoming Watson would have ended up at King’s and not in Cambridge. Wilkins had earlier tried to persuade Randall to find a place at King’s for Crick, but the Professor ha...
متن کاملThe Tuned Singing Burrow of Mole Crickets
During burrow digging by the mole cricket Scapteriscus acletus Rehn and Hubbard, the burrow is enlarged and shaped in a series of digging cycles, each lasting 1—2min, and song chirps are produced after every cycle. The song becomes up to 18 dB louder and acoustically purer during burrow building. The shape of the song pulse envelope changes so that its average power density becomes greater and ...
متن کاملJumping mechanisms and performance of pygmy mole crickets (Orthoptera, Tridactylidae).
Pygmy mole crickets live in burrows at the edge of water and jump powerfully to avoid predators such as the larvae and adults of tiger beetles that inhabit the same microhabitat. Adults are 5-6 mm long and weigh 8 mg. The hind legs are dominated by enormous femora containing the jumping muscles and are 131% longer than the body. The ratio of leg lengths is: 1:2.1:4.5 (front:middle:hind, respect...
متن کاملEvaluation of Turfgrasses for Resistance to Mole Crickets (Orthoptera: Gryllotalpidae)
Bermudagrass (Cynodon sp.) and paspalum (Paspalum vaginatum) genotypes were evaluated in laboratory, greenhouse, and field experiments for potential resistance to the common turfgrass pests, tawny mole cricket (Scapteriscus vicinus Scudder) and southern mole cricket (Scapteriscus borellii Giglio-tos). Potential resistance among 21 seashore paspalums to both insects in an environmental chamber a...
