چکیده

The New Zealand flower thrips, (Thrips obscuratus Crawford) can damage nectarines, with both adults and larvae feeding on developing fruitlets. As T. obscuratus does not overwinter in Central Otago, it is thought that adults are carried on air currents from Canterbury in spring. We investigated if influxes of thrips as detected by sticky board catches over three seasons could be related to environmental variables. Wind direction in Christchurch and local (Clyde) temperatures were identified as the most important factors affecting thrips movement. A preliminary model was developed to predict influxes over the period of highest damage risk for nectarines.

Effects of processing on anthocyanins, carotenoids and vitamin C in summer fruits and vegetables

The purpose of this study was to evaluate the effects of processing, i.e. heating (98 !C, 10 min), freezing (!20 !C) and freeze-drying on anthocyanins, carotenoids, and vitamin C in summer fruits and vegetables, i.e. cherries, nectarines, apricots, peaches, plums, carrots and red bell peppers. The commodities were collected from growers located in the Otago region (namely Cromwell, Roxburgh, Mo...

Spatial and temporal patterns of dispersal of western flower thrips (Thysanoptera: Thripidae) in nectarine orchards in British Columbia.

Thrips were sampled from six nectarine orchards in the Dry Central Interior, British Columbia, Canada, between April and June 1993 using yellow sticky cards on posts spaced around the perimeter of each orchard. Although 12 identified species of thrips were captured, >90% of individuals were the western flower thrips, Frankliniella occidentalis (Pergande). The flight patterns and abundances of w...

Thrips Vectors of Tospoviruses

Tospoviruses belong to the sole phytovirus genus, Tospovirus, in the family Bunyaviridae. Tospoviruses are known to be exclusively transmitted by thrips belonging to the family Thripidae and subfamily Thripinae. Of the known 1,710 species of Thripidae only 14 thrips species are currently reported to transmit tospoviruses. Thrips-transmitted tospoviruses cause severe yield losses to several econ...

Regional and temporal variation in susceptibility to lambda-cyhalothrin in onion thrips, Thrips tabaci (Thysanoptera: Thripidae), in onion fields in New York.

Populations of onion thrips, Thrips tabaci Lindeman, from commercial onion fields in New York were evaluated for their susceptibility to the commonly used pyrethroid, lambda-cyhalothrin (Warrior T), using a novel system called the Thrips Insecticide Bioassay System (TIBS). To use TIBS, thrips are collected directly from the plant into an insecticide-treated 0.5-ml microcentrifuge tube that has ...
