The objective of this study was to determine the potential for several new CM products to flare ERM populations, especially those in the neonicotinoid class, by comparing them to other CM insecticides from the organophosphate, carbamate and pyrethroid classes. Treatment timing was designed to simulate application for CM control. The test materials were applied to 16-yr-old 'Red Delicious' apple...

The tomato red spider mite, Tetranychus evansi, is an invasive pest reported on solanaceous crops in Benin around 2008, causing heavy economic damage. control of this mite by farmers mainly done through intensive applications chemical pesticides that are not always effective. In the present study, we evaluated a laboratory, at IITA-Benin, effects two botanical insecticides: Cashew Nut Shell Liq...

The effectiveness under laboratory conditions of Cinnamon (Cinnamomum verum) on the Tetranychus urticaemite was evaluated. This species is great economic importance because it affects all types crops such as vegetables, fruit trees, and ornamentals. damage consists removal cellular content, leaving cell practically empty. T. urticaehas presented resistance problems to various chemicals, which w...

Dermoscopy is a handy tool originally used for evaluating pigmented lesions and melanoma. However, over the years, numerous indications have cropped up including its role in diagnosing infestations (entomodermoscopy).2 Dermoscopy combines light source and magnifying lens in such a way that it enables visualization of patterns not visible with clinical inspection alone.2 The evidence available r...

Phoretic mites use bark beetles for transportation to new, suitable habitats. Some phoretic act as predators and parasitoids of the beetles’ immature stages, especially egg early larval are potential agents biological control scolytine forest pests. Mites live very frequently in relationships with other invertebrates. Many found association various species beetles. Here, a total 41 specimens di...

The red mite of poultry, Dremanyssus gallinae, is the most important hematophagous ectoparasite of poultry. In this study, pathologic changes of its biting on the poultry skin have been investigated. Thirty-two (Control = 16 and Treatment = 16) four weeks old Ross broilers (308) were infested with the mite on skin of hock joins. Samples were collected after 1, 24, 72 hours and 10 days. The skin...

Abstract Background Poultry red mite (PRM) ( Dermanyssus gallinae ) infestations are a cause of anaemia, impaired productivity and stress-related behaviours linked to reduced hen welfare. A study investigated the potential health, welfare benefits following fluralaner treatment eliminate PRM from infested hens. Methods PRM-infested layer house was selected on free-range farm (5400 hens) an avia...

1. Omnivory, where an animal crosses trophic boundaries, is thought to be common in natural and managed communities. Foraging theory predicts that omnivores will balance their diet as a result of nutritional needs, food quality and availability of alternate foods. We investigated diet selection of the western ̄ower thrips [Frankliniella occidentalis (Pergande)], a herbivore under some circumstan...
