Contributions to the Biology and Ecology of the Oriental Fruit Fly, Dacus dorsalis Hendel (Diptera: Tephritidae), in Hawaii

The Oriental fruit fly, Dacus dorsalis Hendel, was first found in Hawaii in 1945 (van Zwaluwenburg, 1947). During the following year it increased to epidemic populations and caused serious damage to many crops throughout the Hawaiian Islands. Prompt action was taken to combat this pest through the introduction of biological control agents. The purpose of this paper is to present the biology, ecology, and status of D. dorsalis and its principal parasites and to evaluate the role of enromophagous insects that prey upon it

Biology and control of Brevipalpus phoenicis (Geijskes) (Acarina: Tenuipalpidae)

Typescript.Thesis (Ph. D.)--University of Hawaii, 1966.Bibliography: leaves 101-105.vi, 105 l mounted illus., tablesThe red and black flat mite, Brevipalpus phoenicis (Geijskes), has been reported from many countries since its discovery in Holland in 1939 (Geijskes, 1939). This mite is not endemic to the type locality, but is believed to have a tropical origin. However, because of its extensive geographical distribution and host range, the native home of this mite cannot be established. Baker in 1949 reported that several species of Brevipalpus have been found to be pests of cultivated plants, and although not as important as the spider mites they are serious enough at times to warrant investigations of their biology and control. Since then, Manglitz and Cory (l953) and Morishita (1954) have studied in detail the biology and control of B. californicus (Banks) and of B. obovatus Donnadieu, respectively. These two species along with B. phoenicis and B. lilium. Baker make up the known fauna of false spider mites of the genus Brevipalpus in Hawaii. Of these, B. phoenicis is of most concern here in Hawaii for besides damaging many ornamental plants, it attacks two crops of significant economic importance: papaya and passion fruit. B. phoenicis may have been in Hawaii previous to its description date for in 1936 Marlowe (1937) reported a mite injury on papaya fruits with symptoms similar to those now known to be caused by this species. Despite its early presence in Hawaii, very little work has been done in the past on this important mite by other worker So Therefore, a detailed biological study of B. phoenicis has been made and the findings are presented in this thesis so that they may serve as a basis for further studies of this as well as other species of phytophagous mites
