Frankliniella occidentalis is a highly destructive and invasive agricultural pest that has developed resistance to variety of insecticide classes. Different planting structures use frequency can directly affect the development F. occidentalis. In this study, susceptibility three field strains occidentalis, collected over one year (April November) from habitat conditions (facility agriculture ar...

The salmon louse Lepeophtheirus salmonis (Krøyer, 1837) is an ectoparasite causing infections of wild and farmed Atlantic salmon (Salmo salar L.) in the Northern hemisphere. While L. salmonis control at commercial mariculture sites increasingly employs non-medicinal approaches, such as cage designs reducing infection rates and biological control through cleaner fish, anti-parasitic drugs are st...

The impact of salmon lice on the survival of migrating Atlantic salmon smolts was studied by comparing the adult returns of sea-ranched smolts treated for sea lice using emamectin benzoate or substance EX with untreated control groups in the River Dale in western Norway. A total of 143 500 smolts were released in 35 release groups in freshwater from 1997 to 2009 and in the fjord system from 200...

Although vegetable amaranth, Amaranthus viridis L. and A. dubius Mart. ex Thell., production and economic importance is increasing in diversified peri-urban farms in Jamaica, lepidopteran herbivory is common even during weekly pyrethroid applications. We developed and validated a sampling plan, and investigated insecticides with new modes of action, for a complex of five species (Pyralidae: Spo...

This study was aimed to investigate the effects of diosmin (DIO) in rats exposed emamectin benzoate (EB). For this purpose, a total 60 Wistar Albino male rats, aged 6 8 weeks and weighing 180 250 g, were used, 10 each group. The groups determined, respectively, control, EB (10 mg kg-1), DIO (50 (100 kg-1) + indicated doses applied by gavage for 21 days. At end trial period, heart puncture perfo...

The use of biological control products enhances the reduction harmful pressures on environment caused by conventional pesticides. Therefore, this study aims to evaluate toxicity eight bioinsecticides black cutworm Agrotis ipsilon (Hufnagel) (Lepidoptera: Noctuidae) understand relationships between insecticide exposure and insect response at individual population levels. bioassay results showed ...

Helicoverpa armigera (Hübner) is considered one of the most destructive insect pests chickpea crops in Morocco; however, extent yield loss it causes Morocco unknown. This study assessed losses and pod damage caused by borer H. on four improved Kabuli varieties with insecticide treatment at two different locations. The second part this investigated contact systemic toxicity biological selective ...

Managing exotic invasive pests like emerald ash borer can strain budgets and the capacity of cities to protect their urban forest. Area-wide management approaches, SLAM (SL.ow A.sh M.ortality), potentially trees at a greatly reduced cost. We tested this strategy in three forests Indiana by treating 40 % with insecticides. While approach overall mortality untreated trees, survivorship varied con...

The genus Helicoverpa includes several agricultural pests globally. armigera was reported in countries South America 2013, and Puerto Rico, 2014. This territory is considered an hub, with a high-input system of seed production the southern region island, also at edge continental U.S. Possible natural dispersion populations H. from Caribbean or other Central American regions poses continuing ris...
