Chemical attractants for moths

a technology of chemical attractants and moths, which is applied in the direction of nitro compound active ingredients, ammonia active ingredients, drug compositions, etc., can solve the problems of limited use in pest control, affecting the economic injury level of pest moths on crops, and the loss of food supply of caterpillars, so as to prevent essential colony functions or reproduction, reduce the foraging power of the colony, and reduce the degree of control over the colony

Benefits of technology

These attractants effectively lure noctuid moths, including females, allowing for optimized control procedures and population density assessment, reducing pest populations by trapping or killing them, thereby minimizing crop damage.

Problems solved by technology

Larvae or caterpillars of a number of species of moths are serious pests of agricultural crops throughout the world.
They are of limited use in pest control because of the lack of effect on females and because they are not effective as attractants when the same sex pheromones are used for mating disruption by air permeation.
The development of chemical attractants for monitoring pest levels and economic injury levels of pest moths on crops has been hampered by a lack of effective lures for females of these species.
Although numerous synthetic chemical attractants are known for moths, none are based on moth attraction to fermented sweet baits and very few are effective in attracting females.
Many species of noctuid moths are key pests of agricultural crops and cause losses of vegetable, fruit, forage, and fiber crops through direct consumption by larvae and by reduction in food quality.
Many species of armyworms and cutworms are prone to intermittent population outbreaks in some geographic areas, causing severe losses to agricultural crops.

experiment 1

[0072] Traps were baited (1) with 0.25% acetic acid in the drowning solution, (2) with 0.5% acetic acid in the drowning solution and one ml of 3-methyl-1-butanol in a polyethylene cap, or (3) with 200 ml of a 10% solution of molasses in water. A randomized complete block design was used, with 4 blocks set up in early May. Traps were maintained through May and June and again in August.

[0073] Results of Experiment 1. In the first experiment, numbers of males and numbers of females of Lacanobia subjuncta captured in traps baited with acetic acid and 3-methyl-1-butanol were significantly greater than numbers captured in traps baited with acetic acid or with molasses (ANOVA F=31.5 for females, 29.1 for males, df=387) (FIG. 1A). There was no difference between catches of male or female L. subjuncta captured in traps baited with acetic acid versus molasses. Overall, the numbers of males and females captured were similar for all treatments. Numbers of males and numbers of females of L. sub...

experiment 2

[0076] Traps were all baited with one ml of 3-methyl-1-butanol in a polyethylene cap and with either no acetic acid in the drowning solution or with 0.008, 0.03, 0.125, 0.5, or 2% glacial acetic acid by volume in the 200 ml of drowning solution. A randomized complete block design was used, with 4 blocks set up in late July, with each of the 6 treatments represented within each block. This experiment was maintained through August and early September.

[0077] Results of Experiment 2. Numbers of moths captured in traps were suitable for statistical analyses for L. subjuncta (LS) and bertha armyworm (M. configurata) (BAW). Spotted cutworms were not abundant in that study plot. Numbers of L. subjuncta captured in traps baited with the combination of 3-methyl-1-butanol and acetic acid increased significantly with increasing concentrations of acetic acid over the range tested (up to 2%) (FIG. 2). Numbers of moths captured in traps baited with 3-methyl-1-butanol either alone or in combinatio...

experiment 3

[0078] Traps were all baited with 0.25% acetic acid in the drowning solution and either 0, 12.5, 25, 50, or 100% 3-methyl-1-butanol in one ml of a mixture of 3-methyl-1-butanol and mineral oil. A randomized complete block design was used with each of the 5 treatments represented within each block. This experiment was set up in late July and was maintained through early September.

[0079] Results of Experiment 3. Numbers of moths captured in traps were suitable for statistical analyses for L. subjuncta (LS) and bertha armyworm (M. configurata) (BAW). Spotted cutworms were not abundant in that study plot. Numbers of L. subjuncta and numbers of bertha armyworms captured in traps baited with the combination of acetic acid and 3-methyl-1-butanol did not increase significantly with increasing doses of 3-methyl-1-butanol in caps (FIG. 3). For both species, numbers of moths captured in traps baited with acetic acid and 3-methyl-1-butanol at 12.5, 25, 50, and 100% in the cap were similar. At ...

Abstract

Compositions and lures are described which provide synthetic chemical attractants which function as highly effective attractants for male and female moths, primarily moths of the family Noctuidae. In one aspect, the attractants provide an effective attractant amount of vapor of 3-methyl-1-butanol, 3-methyl-1-pentanol or mixtures thereof. In another aspect, the attractants provide vapor blends of acetic acid and one or more compounds selected from the group consisting of 3-methyl-1-butanol, 3-methyl-2-butanol, and 3-methyl-1-pentanol. By attracting male and female moths to traps or baits, the chemical attractants provide a means for detecting, surveying, monitoring, and controlling the moths.

Description

[0001] 1. Field of the Invention[0002] The present invention relates to synthetic chemical insect attractants. More particularly, the invention relates to chemical attractants and use thereof to detect, survey, monitor, and / or control moths (Lepidoptera).[0003] 2. Description of the Art[0004] Many species of moths (Lepidoptera) are pestiferous. Larvae or caterpillars of a number of species of moths are serious pests of agricultural crops throughout the world. In the family Noctuidae, in particular, are many species of cutworms, armyworms, fruitworms, and others that cause severe losses of vegetable and fruit, as well as forage, and fiber crops and necessitate the use of large amounts of pesticides to reduce these losses. Three important species in western North America are the bertha armyworm (Mamestra configurata), the spotted cutworm (Xestia c-nigrum), and Lacanobia subjuncta. These are pests of many vegetable and forage crops, and Lacanobia subjuncta has recently been identified ...
