Population growth and development of the psocid Liposcelis rufa (Psocoptera: Liposcelididae) at constant temperatures and relative humidities.
We investigated the effects of eight temperatures (22.5, 25.0, 27.5, 30.0, 32.5, 35.0, 37.5, and 40.0 degrees C) and four relative humidities (43, 55, 63, and 75%) on population growth and development of the psocid Liposcelis rufa Broadhead (Psocoptera: Liposcelididae). L. rufa did not survive at 43% RH, at all temperatures tested; at 55% RH, at the highest four temperatures; and at 63% RH and ...
متن کاملComparative Susceptibility of Liposcelis bostrychophila Badonnel and Liposcelis decolor (Pearman) (Psocoptera: Liposcelididae) to Spinosad on Wheat
In 2005 the United States Environmental Protection Agency registered spinosad as a grain protectant at 1 μg(AI)/g. The effectiveness of spinosad at 1 μg(AI)/g against many beetle and moth pests of stored grains is well established. In recent years, several psocid species have emerged as economically important pests in various stored-product environments in many countries, including the United S...
متن کاملSampling plans for the psocids Liposcelis entomophila and Liposcelis decolor (Psocoptera: Liposcelididae) in steel bins containing wheat.
Psocids are an emerging problem in grain storage, handling, and processing facilities in the United States. We used data from two steel bins each containing 32.6 metric tonnes of wheat, Triticum aestivum L., to develop sampling plans for Liposcelis entomophila (Enderlein), Liposcelis decolor (Pearman) (both Psocoptera: Liposcelididae), and a mixture of the two species. Taylor's coefficients a (...
متن کاملPHYSIOLOGICAL ECOLOGY Reproductive Parameters of the Parthenogenetic Psocid Lepinotus reticulatus (Psocoptera: Trogiidae) at Constant Temperatures
We investigated effects of temperature, at 70% RH, on the reproductive parameters of the parthenogenetic psocid Lepinotus reticulatus Enderlein (Psocoptera: Trogiidae). The lowest fecundity (21) was at 35 C and the highest (41) at 27.5 C. At 22.5, 25, and 27.5 C, peak oviposition rates (eggs/female/week) occurred in week 3 and were 4.7, 6.6, and 7.8, respectively; also 51, 57, and 62%, respecti...
متن کاملTemporospatial distribution of the psocids Liposcelis entomophila and L. decolor (Psocoptera: Liposcelididae) in steel bins containing wheat.
We studied the temporospatial distribution of psocids in steel bins containing 32.6 tonnes of wheat in 2005 and 2006 in Manhattan, KS. Psocids were sampled in the top 0.9 m of wheat using a 1.2-m open-ended trier; samples were taken from the bin center and in the four cardinal directions at 0.15 and 0.76 m from the bin wall. In addition, a 2.4-m partitioned grain trier with 16 compartments was ...
