Abundance Factors /

The abundance of mymarid parasitoids attacking the two-spotted leafhopper (Sophonia rufofascia [Kuoh and Kuoh]), a polyphagous pest recently adventive to Hawaii, was monitored using yellow sticky cards deployed in several areas on the islands of Kauai and Hawaii. The yellow cards captured Chaetomymar sp. nr bagicha Narayanan, Subba Rao, & Kaur and Schizophragma bicolor (Dozier), both adventive species; as well as Polynema sp. Haliday, […]

Abundance Factors /

The two-spotted leafhopper, Sophonia rufofascia (Kuoh and Kuoh), is a recent invasive pest attacking a wide variety of plant species in Hawaii. We surveyed the distribution and parasitism of its eggs in a number of natural and agricultural habitats on the islands of Kauai, Oahu, and Hawaii. Egg density was fairly low, with egg distribution affected both

The flower-head feeding fly Acinia picturata (Diptera: Tephritidae) was deliberately introduced from Mexico into Hawaii in 1959 for biological control of the exotic weed Pluchea odorata (Snow) (Asteraceae). Neither field efficacy nor possible non-target effects of the fly have been evaluated in the 40 years since the introduction. We assessed the impact of the fly on both its target

Abundance Factors

Kallitaxila granulata (Stal) (Homoptera: Tropiduchidae), a recent invasive species in Hawaii, is a potential pest of agricultural and forest ecosystems. We present information on the planthopper’s oviposition behavior, its egg distribution patterns, and the occurrence of egg parasitoids in Hawaii. There were no differences in the percentage of leaves containing K. granulata oviposition scars or in the number

Abundance Factors, Insecticides /

Methyleugenol-baited traps are used for Oriental fruit fly control through male annihilation, as well as for detection and monitoring of fly populations. However, if the males which come to these traps emit sex pheromones, attract females from the surrounding vegetation, and mate with them before being killed, then using such traps might in fact increase

We performed a series of laboratory experiments to determine the effects of shade, soil moisture, and soil compaction on the selection of pupation habitats by wandering late instar Oriental fruit flies, Bactrocera dorsalis (Hendel). Larvae showed a strong preference towards pupating in shaded rather than brightly lit areas, in moist rather than dry soil, and in soil

Abundance Factors /

An effective lure-and-kill trap is a potentially important instrument in monitoring and controlling Oriental fruit flies, Bactrocera dorsalis(Hendel). A number of experiments were performed in a commercial guava (Psydium guajava L.) orchard to determine how fly captures are affected by combining visual and olfactory stimuli, and by the timing of trap deployment relatively to host phenology.

Colorado potato beetle dispersal and reproduction was investigated under field and laboratory conditions. Movement and mating of newly emerged summer-generation Colorado potato beetle adults was monitored in the field using a mark-recapture technique, and beetle mating within experimental plots was recorded. The number of degree-days (DD) required for the beetles to become reproductive was tested
