The collected blood samples were immediately placed in heparinized tubes containing dichlorvos
(5 [micro]L of 8 mg/mL dichlorvos
in normal saline) for inhibition of carboxylesterase , followed by centrifugation to obtain the plasma and stored at -80[degrees]C.
Comparatively, exposure of rats to dichlorvos
and diazinon for 9 weeks did not change the testis, epididymis weight, and testicular structure but the histopathological alterations were observed in the epithelial cells in epididymis, in which increased cytoplasmic vacuolation and nuclear shrinkage were found .
Naled's breakdown product, dichlorvos
, works similarly (Cox, 2002).
These volatiles can be less toxic to humans than synthetic fumigants such as sulfuryl fluoride and dichlorvos
, so this research may lead to the development of a relatively safe and possibly effective home remedy for bed bug infestations that involve smaller personal items such as purses, carriers and luggage bags.
The most widely used molecules in pets are: coumaphos, cythioate, diazinon or dimpylate, dichlorvos
, fenitrothion and fenthion (Agbolade et al., 2008).
Lethal and sublethal doses of the formulated grade Dichlorvos
(DDVP 1000EC) and Cyperforce (Cypermethrin 10% EC) were administered to worker bees by contact (topically) to identify if the products have low non-target activity.
Although, the insecticidal activity of essential oil is much less than that of synthetic insecticides such as dichlorvos
, propuxor and permethrin, they are quite harmless.
