Certain polybutylbenzylphenols and benzyl-3,4-methylenedioxybenzenes are useful for insect control especially as insect chemosterilants and oviposition inhibitors. The benzyl-3,4-methylenedioxybenzenes also find utility as growth inhibitors for mosquito larvae.

Poly-t-butyl-cinnamyl phenols and poly-t-butyl-dihydrocinnamyl phenols are disclosed to be useful for inhibiting the growth of mosquito larvae, thus providing means for controlling mosquito populations.

Growth inhibitors for mosquito larvae

New polybutyl-2-cinnamylphenols, particularly 4,6-di-t-butyl-2-cinnamylphenol, are useful for insect control and especially as insect chemosterilants and oviposition inhibitors.

Polybutyl-2-cinnamylphenols as insect anti-procreants

Substances, particularly wood, which are normally subject to deterioration due to marine borers are preserved by applying to the substance a dibutylbenzylphenol.

Process for inhibiting the deterioration of wood due to marine boring

Substances, particularly wood, which are normally subject to deterioration due to marine borers are preserved by applying to the substance certain 4-(3-phenylpropenylidene)-2,5-cyclohexadieneones substituted at position 5 with substituents selected from the group consisting of lower alkyl, lower alkoxy, and hydrogen, and at position 2 with substituents selected from the group consisting of hydroxyl and lower alkoxyl.

Control of marine borer attack on wood

Alkyl-substituted 2-benzylphenols are disclosed to be useful for repelling the confused flour beetle (Tribolium confusum).

Certain cinnamyl phenols as growth inhibitors for mosquito larvae

Limonene (or alpha-pinene) is condensed with sesamol under aqueous acidic conditions to produce a mixture of two novel compounds which are useful as mosquito larvicides.

Mosquito larvicide

New cinnamyl-sesamol derivatives, for example, 3,4-methylenedioxy-cinnamyloxybenzene, 2-methoxy-4,5-methylenedioxycinnamylbenzene, 2-ethoxy-4,5-methylenedioxy-cinnamylbenzene, and 2-allyloxy-4,5-methylenedioxy-cinnamylbenzene are useful for insect control, particularly as insect chemosterilants.
