A common practice in highbush blueberry (Vaccinium corymbosum L.) culture is to use combinations of insecticides and fungicides to reduce the number and cost of pesticide applications. In response to apparent phytotoxicity observed in commercial fields that were treated with combinations of diazinon and captan formulations, phytotoxicity of two formulations of diazinon (Diazinon AG600 and Diazi...

and insecticides are incorporated during acid delinting and just before seed is bagged. An additional dipper can be added to commercial chemical treaters to meter 30 cc of AMP in water solution at the same time PCMB, Captan, and insecticide treatments are added to each eight pound "dump" of cottonseed. Alternatively, concentration of AMP can be increased, and it can be used as the aqueous porti...

Toxic effects on Apis mellifera L. of the neonicotinoid insecticides Thiametoxam, Clothianidin, Acetamiprid and Thiacloprid were tested in the laboratory. Commercial formulations, dispersed in sugar syrup and water, at the highest dose level marked on the label were used to carry out oral and indirect contact trials on each pesticide. Clothianidin and Thiametoxam caused higher mortality than th...

INTRODUCTION Several arthropod pests infest strawberry crop in California and cause a significant yield loss according to Zalom, Bolda, Dara, and Joseph [1]. Strawberry is an important commercial crop and the annual report from California Department of Pesticide Regulations [2] indicates that large quantities of acaricides, fungicides, herbicides, and insecticides are applied to manage a variet...

The population structure of the Polynesian mosquito Aedes polynesiensis was investigated using electrophoretic data from two polymorphic protein loci. Considerable differentiation was observed both within and between islands in different archipelagos (Society, Tuamotu, Austral). Gene flow evaluated by Fst estimates was independent of geographic distance between islands but related to commercial...

Polychlorinated biphenyls (PCBs) have been useful industrial products since the beginning of their commercial production in 1929. The first report of PCBs occurrence in wildlife was made from the work of S6ren Jensen, a Swedish Chemist, in the New Scientist in 1966 (1). Since then PCBs have been reported to be widespread in the world's ecosystem, building up in food chains as has been reported ...

Three neonicotinyl insecticides, acetamiprid, thiacloprid and clothianidin, were evaluated for their impact on four species of lepidopteran pests of apple in Washington, the codling moth, Cydia pomonella (L.), the Pandemis leafroller, Pandemis pyrusana Kearfott, and the obliquebanded leafroller, Choristoneura rosaceana (Harris), and Lacanobia subjuncta (Grote & Robinson). None of the neonicotin...

To reduce the detrimental effect of insecticides, an effective Integrated Pest Management (IPM) module is necessary for eco-friendly management Maruca vitrata in garden bean ecosystem. Two field trials were carried out to evaluate efficacy different insecticides and botanicals against M. on Lablab purpureus var. typicus. seasons evaluation revealed that chlorantraniliprole 18.5 SC was most trea...
