insecticidal efficacy of iranian diatomaceous earths on adults of oryzaephilus surinamensis
diatomaceous earth (de) is a dust composed of fossilized bodies of unicellular algae used as an insecticide. in this study, the insecticidal potential of four iranian de deposits was assessed in adults of oryzaephilus surinamensis (l.). three of de deposits were collected from maragheh, mamaghan, and khorasan jonoobi mines and sayan® formulation was obtained from kimia sabz avar company. the in...
متن کاملHorizontal Transfer of Diatomaceous Earth and Botanical Insecticides in the Common Bed Bug, Cimex lectularius L.; Hemiptera: Cimicidae
BACKGROUND Horizontal transfer of insecticide occurs when insects contact or ingest an insecticide, return to an aggregation or a nest, and transfer the insecticide to other conspecific insects through contact. This phenomenon has been reported in a number of insects including social insects, however it has not been reported in bed bugs. Since horizontal transfer can facilitate the spread of in...
متن کاملDiatomaceous Earth for Pest Control
Least toxic physical and chemical solutions are often part of an IPM program. Various forms of amorphous silica are commonly used as part of this strategy. Diatomaceous earth and silica gel are used in various physical formulations with or without added pesticide. The type of silica and the formulation depend on the target pest. In this issue advantages and disadvantages of diatomaceous earth a...

متن کاملMelting in super-earths.
We examine the possible extent of melting in rock-iron super-earths, focusing on those in the habitable zone. We consider the energetics of accretion and core formation, the timescale of cooling and its dependence on viscosity and partial melting, thermal regulation via the temperature dependence of viscosity, and the melting curves of rock and iron components at the ultra-high pressures charac...
