Parasitism of Dasineura oxycoccana (Diptera: Cecidomyiidae) in North Central Florida.
Blueberry gall midge, Dasineura oxycoccana (Johnson), is a key pest of blueberries in Florida. As a larva, this insect feeds in developing flower and leaf buds. Management of D. oxycoccana relies principally on chemical insecticides; however, efficacy is limited because D. oxycoccana is sheltered within the plant during most of its life cycle. Natural enemies, particularly parasitoids, may play...
متن کاملStrawberry Guava (Psidium cattleianum) – Prospects for Biological Control
Strawberry guava Psidium cattleianum Sabine (Myrtales, Myrtaceae) was introduced to Hawaii about 1825 and quickly escaped from cultivation. It is now found on all inhabited islands where it is one of the most important forest weeds. The small trees form extremely dense monotypic stands up to 10 m in height. Four insect species were found that have significant deleterious effects and, therefore,...
متن کاملThe genus Dasineura Rondani, 1840 (Diptera, Cecidomyiidae) in Brazil.
Dasineura (Diptera, Cecidomyiidae) is the gall midge genus with the highest number of known species (466 throughout the world). Only 39 species have been described from the Neotropics, being 10 from Brazil. Many records of not determined species are found in the literature. Furthermore, many unidentified specimens are deposited in the Cecidomyiidae Collection of the Museu Nacional/UFRJ, which c...
متن کاملCharacteristics of the Psidium cattleianum (Myrtaceae) Seed Bank in Hawaiian Lowland Wet Forests
Psidium cattleianum Sabine (strawberry guava) is one of Hawai‘i’s most disruptive alien plants. Dense stands can suppress growth and establishment of native species, support high populations of crop-damaging fruit flies, and preclude restoration or management of native forests. Our research investigated factors affecting persistence of P. cattleianum seeds in lowland wet forest soils. We collec...
متن کاملAssessing the Economic Importance of Dasineura oxycoccana (Diptera: Cecidomyiidae) in Northern Highbush Blueberries.
Infestation by blueberry gall midge, Dasineura oxycoccana Johnson, is common in northern highbush blueberries, but its effects on crop productivity are unknown. We examined whether infestation by blueberry gall midge reduces flower bud production when compared with uninfested shoots, and how infestation at different times affects the crop response. From the fall of 2009 to the spring of 2011, t...
