Definitions

  • the present disclosure relates generally to products and methods for controlling the tomato leaf miner, Tuta absoluta. More particularly, this present disclosure relates to methods and compositions for attracting the tomato leaf miner, for purposes of both population control and monitoring through the use of novel kairomone blends with potent and varied behavioral effects.
  • These kairomone blends can be employed in a broad range of means, including a monolithic lure and attractant-impregnated adhesive to be deployed in monitoring traps, and a liquid formulation that can be blended with insecticide to create an attract and kill product amenable to spray application. It is also deployable in larger quantities in strategically placed, self-contained bait stations.
  • insects of all species rely predominantly on chemicals detected in their environment for virtually every critical aspect of their lives, from females’ selection of appropriate sites upon which to deposit their eggs, location of desirable habitats and food sources and the avoidance of undesirable ones, to the finding and selection of a mate.
  • behaviormodifying chemicals known collectively as semiochemicals
  • a killing agent typically a small quantity of insecticide
  • this attractant could be deployed as a long-lasting monolithic lure, to be placed in virtually any type of trap, or it could be blended directly into an adhesive for a sticky trap.
  • the attractant can also be blended with a small quantity of insecticide to create an A&K formulation.
  • the A&K technique of pest control consists of attracting adult males, females, or both sexes of a pest species to an insect control agent (e.g., insecticide, sterilant, or insect pathogen).
  • the insect attractant can be a chemical attractant, a visual cue, an acoustic cue, or a combination of these.
  • a highly effective attractant and appropriate insecticide are indispensable ingredients of an effective A&K product.
  • insect pests must be lured to a toxicant, which they must contact and/or feed upon. Contact with the toxicant must then either kill the insect or, at minimum, result in sublethal effects that preclude that insect from effectively performing behaviors that are essential to its survival (feeding behavior, escape responses, etc.), or the survival of its population (effective courtship, mating success).
  • the attractant must be at least as effective, if not more so, as attractants naturally present in the environment, so that the A&K formulation successfully out- competes them and lures the insect pest to the control agent. In many cases, the A&K also contains phagostimulants that induce the insect pest to consume the toxicant formulation.
  • One way for A&K formulations to outcompete existing, natural sources of the stimuli in the treated environment is by having point sources present at significantly higher densities than the competing natural sources, and/or by being significantly more attractive to the target pest.
  • A&K techniques present many advantages over cover sprays of conventional insecticides. Attract and kill typically deploys smaller amounts of toxicants, often contained within discrete point sources and coupled to a species-specific attractant, reducing the likelihood of negative environmental and non-target effects. There are also substantial economic benefits to the use of A&K over blanket pesticide sprays.
  • compositions for affecting Tuta absoluta comprising a blend of a-phellandrene; a-terpinene; limonene; P-cymene; Terpinolene; Carvacrol; and B-caryophyllene.
  • the composition comprises approximately 6.6% by weight a- phellandrene; approximately 7.59% by weight a-terpinene; approximately 33.3% by weight limonene; approximately 2.48 % by weight P-cymene; approximately 4.39% by weight Terpinolene; approximately 0.23% by weight Carvacrol; approximately 33.86% by weight B- caryophyllene; and approximately 11.55% by weight BHT.
  • composition may further include a pesticide.
  • This pesticide may be any suitable pesticide, and in certain embodiments may be methomyl.
  • One embodiment contains approximately 1% by weight methomyl.
  • the composition may be able to attract Tula absoluta, and may further be able to attract both male and female Tuta absoluta.
  • the composition may be contained within a substrate.
  • suitable substrates are recited in U.S. Patent No. 7,887,828 titled Dual Action Organic Formulation to Control Two Stages of Insect Pests, the entirety of which is incorporated by reference herein.
  • the substrate may, for example, be a wax emulsion, microspheres, a latex solution, hot melt glue, a resin, or plastic flakes.
  • the substrate is a wax emulsion
  • it may be a wax carrier such as a paraffin wax, carnauba wax, beeswax, candelilla wax, fruit wax, lanolin, shellac wax, bayberry wax, sugar cane wax, microcrystalline wax, ozocerite, ceresin, montan wax, or combinations thereof.
  • the wax emulsion may include 30% by weight paraffin wax; 4% by weight soy oil; 2% by weight sorbitan monostearate; 1% by weight vitamin E; and 58% by weight distilled water.
  • the wax emulsion may include 45% by weight microcrystalline wax; 6% by weight soy oil; 3% by weight sorbitan monostearate; 1% by weight vitamin E; and 40% by weight distilled water.
  • the substrate may be a hot melt glue.
  • the hot melt glue may be, for example, a polymer of ethylene-vinyl acetate, polyethylene, polypropylene, a polyamide, or a polyester.
  • Another embodiment of the present disclosure is directed toward methods of affecting Tuta absoluta populations.
  • the method includes administering a composition to a region known or suspected to contain Tuta absoluta, wherein the composition includes a-phellandrene; a- terpinene; limonene; P-cymene; Terpinolene; Carvacrol; and B-caryophyllene.
  • the method may be used to attract Tuta absoluta, and more particularly may attract male or female Tuta absoluta.
  • the composition in this method may further include a pesticide in order to kill the Tuta absoluta.
  • the study was carried out over a three day period, in a 1.5 ha area of tomatoes produced in a conventional cultivation system.
  • the experimental design used was completely randomized, with six treatments plus a control (four replications per treatment).
  • the treatments consisted of different food attractant formulations: XF0302Aol; XF0302Ao2; XF0302Ao3; XF0302Aol + XF0066Ao4; XF0302Ao2 + XF0066Ao4; XF0302Ao3 + XF0066Ao4.
  • water was used.
  • all treatments, including the control 1% of the insecticide methomyl was added.
  • Each replicate consisted of a trap made from a 5-L plastic bottle with four lateral openings cut into it. A 250-mL quantity of the experimental attractant was placed at the bottom of the trap (one experimental attractant applied to each trap). Traps were randomly distributed in the production area installed in the shade at 1.0-1.2 m above the soil surface and monitored every 24 hours for 3 consecutive days.
  • the traps were prepared, installed, and evaluated during the experiment.
  • the evaluation consisted of daily counts of the captured insects, especially Tuta absoluta, the captured insects being removed from the traps with tweezers.
  • Trap count data were transformed into (Qx + 0.5) and subjected to analysis of variance (ANOVA) at the level of 5% probability. When significant, the means were compared with each other by the Duncan test at the 5% probability level.
  • the study was carried out over a three day period in a 0.85-ha area of tomatoes produced in a conventional cultivation system.
  • the experimental design used was completely randomized, with six treatments plus a control (four replications per treatment).
  • the treatments consisted of different food attractants formulations: XF0302Aol; XF0302Ao2; XF0302Ao3; XF0302Aol + XF0066Ao4; XF0302Ao2 + XF0066Ao4; XF0302Ao3 + XF0066Ao4.
  • water was used.
  • all treatments, including the control 1% of the insecticide methomyl was added.
  • Each replicate consisted of a trap made from a 5-mL plastic bottle with four lateral openings cut into it. In each trap, 250 mL of the test attractant was applied at the bottom, and traps were randomly distributed in the production area. Traps were installed in the shade 1.0-1.2 m above the soil surface and monitored every 24 hours for 3 consecutive days.
  • the evaluation consisted of daily counts of the captured insects, especially Tuta absoluta. Captured insects were removed from the traps with tweezers. Trap count data were transformed into (Qx + 0.5) and subjected to analysis of variance (ANOVA) at the level of 5% probability. When significant, the means were compared with each other by the Duncan test at the 5% probability level.
  • the attractant XF0302Aol captured the highest numbers of Tuta absoluta moths.
  • the other attractants also captured adults of this species, while no T. absoluta individuals were captured in the control.
  • the attractants XF0302Aol, XF0302Ao2, and XF0302Ao3 captured the most T. absoluta moths.
  • the other attractants also captured adults of this species, but the XF0302Aol + XF0066Ao4 and XF0302Ao2 + XF0066Ao4 treatments did not achieve significantly higher trap capture rates than the control.
  • XF0302Aol and XF0302Ao3 captured more T. absoluta adults than any of the other treatments tested.
  • the other attractants also captured adults of the species in smaller quantities; no T. absoluta moths were captured in the control.
  • the attractant XF0302Ao2 stood out. It should be noted that in the previous evaluation, it was, numerically, the second that most captured insects. The other attractants also captured adults of this species, while only one insect was captured in the control.
  • the attractant XF0302Ao2 captured the highest number of T. absoluta adults.
  • the other attractants also captured adults of this species, while control traps captured none.
  • the attractants XF0302Aol, XF0302Ao2, and XF0302Ao3 are effective for capturing T. absoluta adults, but this effectiveness is reduced when XF0066Ao4 is added to the formulation.
