The influence of oxygen on the toxicity of fumigants to Sitophilus granarius (L)

Journal of Stored Products Research, 1967
Abstract The toxicity of six fumigants—methyl bromide, ethylene dibromide, ethylene oxide, hydrogen cyanide, hydrogen phosphide and carbon tetrachloride to S. granarius was determined in atmospheres containing 0, 1, 3, 20·9 and 100 per cent oxygen. Toxicity was generally increased with decreasing oxygen concentration until the latter was reduced to

Some factors affecting the physical toxicity of fumigants

Journal of the Science of Food and Agriculture, 1957
AbstractThe fumigant toxicities to the grain weevil Calandra granaria of 39 alkyl chlorides, bromides and thiocyanates have been estimated with considerable accuracy. The difference between toxicities of isomers on the thermodynamic scale is small, except near the cut‐off point, or when instability or chemical reactivity are evident.

The toxicity of twelve fumigants to three species of mites infesting grain

Journal of Stored Products Research, 1981
Abstract Eggs of Tyrophagus longior, Acarus siro and Glycyphagus destructor were highly tolerant of each fumigant tested at 10°C while mobile stages were susceptible. Some eggs of T. longior survived the highest test dosages of methyl bromide, phosphine, ethylene oxide, ethyl formate, methallyl chloride and ethyl bromide.

Toxicity of Seven Candidate Fumigants to Stored-Product Insects

Journal of Economic Entomology, 1966
Laboratory studies were conducted to compare the toxicity of 7 candidate fumigants with methyl bromide (reference standard) to adults of confused flour beetle, Tribolium confusum Jacquelin du Val and of cigarette beetle Lasioderma serricorne (F.), and larvae of black carpet beetle, Attagenus piceus (Olivier).

Fumigant toxicities of essential oils and monoterpenes against Lycoriella mali adults

Crop Protection, 2006
Abstract Toxicity of various essential oils and their volatile components against the mushroom sciarid, Lycoriella mali was determined. The most potent fumigant toxicity was found in essential oil from thyme followed by the oils of sage, eucalyptus, and clove bud. α-Pinene was the most toxic fumigant compound found in thyme essential oil ( LD

Evaluation of fumigant toxicity of cyclohexanone to 5 species of insect pests

Journal of Economic Entomology
Abstract Cyclohexanone is a major precursor for nylon production and is also used as a pesticide solvent. In this study, cyclohexanone was evaluated as a fumigant against rice weevil adults, confused flour beetle adults, western flower thrips larvae and adults, spotted wing drosophila adults, and subterranean termite workers ...
