Flight of the eye gnat, Hippelates pallipes (Diptera: Chloropidae): correlation with temperature, light, moisture and wind velocity.
The flight activity, based on collections from humans, of Hippelates palliPes (Loew) eye gnats was measured under varying field conditions. Thresholds for flight were 18°C, 5.38 milliphots (5 ft-c) of light, and wind speed below 60-70 mfmin. No gnats were captured at a vapor pressure deficit of 0.0 mm Hg. Graphs are presented for flight activity at various values of temperature, light, VPD, and...
متن کاملSusceptibility of the adult eye gnat Liohippelates collusor (Diptera: Chloropidae) to neonicotinoids and spinosad insecticides.
Imidacloprid, thiamethoxam (first and second generation neonicotinoid insecticides), and spinosad (a naturally derived biorational insecticide) were evaluated in the laboratory against adult eye gnats, Liohippelates collusor (Townsend), using two modes of exposure. Ingestion experiments revealed that toxicity was the highest for thiamethoxam (Platinum soluble concentrate) followed by technical ...
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولControl of aggregated populations of the eye fly Siphunculina funicola (diptera: chloropidae) using pyrethroid aerosols.
Three commercially available insecticide aerosol compositions containing cyphenothrin, imiprothrin, cypermethrin, d-tetramethrin and permethrin, in various combinations and concentrations were evaluated for control of the oriental eye flies Siphunculina funicola (de Meijere) from their aggregation substrates in two villages in the Chon Buri Province, Thailand. Each aerosol produced almost compl...
متن کاملThe Protective Effect of Lichen in Maintaining Moisture and Modulating the Temperature Fluctuations of Soil Susceptible to Wind Erosion
Extended abstract 1- INTRODUCTION Soil erosion is one of the most destructive processes of arid and semi-arid areas, which leads to desertification in a large area of the region. In windy areas, the wind in the region increases the probability of wind erosion. Soil moisture and soil temperature are the two effective factors in soil erosion control. Vegetation is also one of the effectiv...
