Problems solved by technology

Attempts to develop a system utilizing both methyleugenol and eugenol have not proven to be successful, however, because the ability of eugenol and eugenol to attract Drosophila orientalis has been shown in several reported studies antagonistic or inh

Embodiment I

[0076] To prepare the formulation, a biodegradable wax carrier (e.g., paraffin or microcrystalline wax) is heated to a liquid state and mixed with attractants (i.e., methyl eugenol, muscarin, and optionally additional attractants) and water. Mix thoroughly to form an emulsion. Optionally, an effective amount of an emulsifier (for example, sorbitan monostearate), a preservative, an antioxidant, a UV stabilizer, an insect poison (for example, spinosad or spinosad), and / or Or an effective amount of an insect visual attractant (eg, Green Food Colorant available from McCormick & Co., Hunt Valley, Md.) is blended into the emulsion. The mixture is then cooled or allowed to cool. Once the formulation has reached room temperature, it is transferred to final packaging.

[0077] In an alternative way of preparing formulations, preparation or obtaining includes a biodegradable wax carrier and optionally includes one or more additives (i.e., water, emulsifiers, preservatives, antioxidant...

Embodiment II

[0079] Three formulations (I-III) were prepared by mixing the components in the proportions indicated in Table 1 at room temperature using a spatula. Preformulated carrier mixture emulsions were prepared according to US Patent 6,001,346.

[0081]

Embodiment III

[0083] The efficacy of Formulations I-III of Table I was tested in an outdoor environment at various papaya field locations under the surrounding Hawaiian climate conditions. In a 100 acre papaya field on Kauai, Hawaii, pellets of Formulations I and III (2 g each) and Formulation II (4 g each) were placed in fruit fly traps. The experimental design was a randomized full module with four traps per treatment. Divide the 100 acre field into four modules and place one trap / agent into each module at a minimum distance of 100ft from each other. Rotate the traps within each module clockwise one position per week to compensate for placement effects within the module. The traps containing the formulation were kept in the field for 6 weeks under normal environmental conditions (light, temperature, rain, etc.). The preparations were aged under normal conditions and the number of flies in each trap was scored weekly for 6 weeks.

[0084] The results are stated below figure 1 with 2 ....

Abstract

An insect control formulation including methyl eugenol, cue lure and a biodegradable wax carrier is a surprisingly effective attractant for Oriental fruit flies (Bactrocera dorsalis) and Melon flies (Bactrocera cucurbitae). Formulation embodiments that include at least one insect toxicant are surprisingly effective for use in fruit fly MAT attract and kill systems, and are suitable for on-crop or off-crop uses. Formulation embodiments can be provided as aqueous emulsions having viscosities appropriate for use in aerial or backpack spray applications or for delivery using caulk gun-type or grease pump-type devices. Other formulation embodiments can be provided as solid blocks, granules or powders.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to US Provisional Application 61 / 646,565, filed May 14, 2012, and US Provisional Application 61 / 647,322, filed May 15, 2012, each of which is incorporated herein by reference. Background technique [0003] The present invention provides an insect attractant formulation that is effective for controlling insect populations using the male-killing technique (MAT), and an insect control method using the same. More particularly, the present invention relates to sprayable or solid biodegradable formulations comprising the insect-like pheromones (para-pheromones) methyl eugenol and cue lure in combination with a biodegradable wax carrier . The formulation is effective to continuously release methyl eugenol and muscarin from the carrier over an extended period of time effective to attract members of the target insect population. The formulation can be used without the need for ins...
