An unsaturated hydroxyl-ester pheromone for the neotropical root weevilhas been isolated, identified and synthesized. It is useful for trapping the weevil to reduce or prevent damage to plants.

[object Object]

A composition for attracting female tropical root weevils (and/or repelling male tropical root weevils), containing (&#xb1;)-linalool, cis-3-hexen-1-ol, and carvacrol, and optionally a carrier or carrier material known in the art. A method for attracting female tropical root weevils to an object or area, involving treating the object or area with a composition containing a female tropical root weevil attracting effective amount of (&#xb1;)-linalool, cis-3-hexen-1-ol, and carvacrol, and optionally a carrier or carrier material. A method for repelling male tropical root weevils from an object or area, involving treating the object or area with a composition containing a male tropical root weevil repelling effective amount of (&#xb1;)-linalool, cis-3-hexen-1-ol, and carvacrol, and optionally a carrier or carrier material.

A method has been discovered for attracting Colorado potato beetles to an area of object or area, which method involves treating the object or area with a Colorado potato beetle attracting composition which contains a carrier material and a Colorado potato beetle attracting effective amount of (S)-3,7-dimethyl-2-oxo-oct-6-ene-1,3-diol.

Attractant pheromone for the Colorado potato beetle

A method has been discovered for attracting Colorado potato beetles to an area of object or area, which method involves treating the object or area with a Colorado potato beetle attracting composition (with or without an insecticide) containing a carrier material and a Colorado potato beetle attracting effective amount of (a) (Z)-3-hexenyl acetate, (&plusmn;)-linalool, nonanal, and methyl salicylate, (b) (Z)-3-hexenyl acetate, (&plusmn;)-linalool, and methyl salicylate, (c) (Z)-3-hexen-1-ol, (E)-2-hexen-1-ol, and (&plusmn;)-linalool, (d) (Z)-3-hexenyl acetate and methyl salicylate, or (e) (Z)-3-hexenyl acetate and (&plusmn;)-linalool. Furthermore, a method has been discovered for repelling Colorado potato beetles from an object or area, comprising treating the object or area with a Colorado potato beetle repelling composition (with or without an insecticide) containing a carrier material and a Colorado potato beetle repelling effective amount of (Z)-3-hexen-1-ol, (E)-2-hexen-1-ol, (&plusmn;)-linalool, nonanal, methyl salicylate, and &bgr;-caryophyllene.

Attractants and repellants for colorado potato beetle

Green leaf volatiles were found to synergize the attractant effect of insect pheromones on boll weevils, European elm bark beetles, and Mediterranean fruit flies. Trans-2-hexen-1-ol, hexanal, trans-2-hexenal, cis-3-hexen-1-ol, and 1-hexanol were most effective. These sounds will be useful in control of insect populations.

Green leaf volatiles as synergists for insect pheromones

A composition for preventing or limiting the attack and infestation of trees by pine bark beetles, by inhibiting the response of the beetles to their aggregation pheromones. The composition comprises a green leaf volatile selected from six carbon alcohols, aldehydes, their derivatives such as acetates, and mixtures thereof. The green leaf volatile may be employed alone or in combination with an additional, known inhibitor of the pheromone response of the beetle.

Green leaf volatiles as inhibitors of bark beetle aggregation pheromones

This invention is directed to insect control using compositions having attractants, feeding stimulants and toxicants compounded into plastic bait pellets. These pellets are easily handled for distribution in the field. Insects are attracted to the bait pellets, induced to feed and subsequently die. The pellets have the unique advantage of being relatively impervious to environmental conditions and non-polluting.

Plastic bait composition for attracting and killing crop pests

A composition for preventing or limiting the attack and infestation of trees by pine bark beetles, by inhibiting the response of the beetles to their aggregation pheromones. The composition comprises a green leaf volatile selected form six carbon alcohols, aldehydes, their derivatives such as acetates, and mixtures thereof. The green leaf volatile may be employed alone or in combination with an additional, known inhibitor of the pheromone response of the beetle.

A sex pheromone composition for southwestern corn borer male moths consisting essentially of Z9-Hexadecenal in an amount of about 16-26% by weight, Z11-Hexadecenal in an amount of about 56-85% by weight, and Z13-Octadecenal in an amount of about 6-10% by weight.
