DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION
(15) From time-to-time, the present invention is described herein in terms of example environments. Description in terms of these environments is provided to allow the various features and embodiments of the invention to be portrayed in the context of an exemplary application. After reading this description, it will become apparent to one of ordinary skill in the art how the invention can be implemented in different and alternative environments.
(16) Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of ordinary skill in the art to which this invention belongs. All patents, applications, published applications and other publications referred to herein are incorporated by reference in their entirety. If a definition set forth in this section is contrary to or otherwise inconsistent with a definition set forth in applications, published applications and other publications that are herein incorporated by reference, the definition set forth in this document prevails over the definition that is incorporated herein by reference.
(17) The present invention may be employed to control insects by selecting the proper lure mixed with a wax and a wax thinning agent and the proper toxicant. Insects may include insects tephritid fruit flies, yellow jackets and cockroaches for example.
(18) The present invention is directed toward an insect control system 10. In one variant, referring to
(19) Any wax is suitable that is reasonably hard at room temperature and can be softened by incorporating mineral oil. Ambient air temperature coupled with how much the wax is thinned can be used to control the volatilization of the pheromone and toxicant and also allow the target insect's mandibles to pierce into the softened wax. When a target insect's mandibles pierce into the softened wax, that action opens a new little bubble of lure/toxicant to become even more attractive and toxic.
(20) Of importance is to make sure that the waxy mixture becomes softened for the insect's mouth parts, while the melting temperature of the mixture is high enough to prevent melting from environmental factors like sun, heat and rain.
(21) Using organic bee's wax allows the lure to be fully USDA certified organic.
(22) Bees' wax (which melts at about 145° F.) combined with mineral oil forms a pliable mixture to makes the pheromone/toxicant less susceptible to rain and sun that normally causes rapid volatilization with rapid attraction and toxicity deterioration. In one variant, an electric whisk/beater is optionally used to beat as much air into the mixture as possible to make it easier for an insect's mandibles to pierce into the mixture, also causing new surface area to be created for controlled volatilization of the pheromones and flash toxicant.
(23) In one example, to make 3,335.61 total lure mixture, 1213.80 grams bees' wax, 1482.34 grams mineral oil, 383.68 ml ethyl methyl eugenol (pheromone), and 255 grams 22.8% spinosad (organic fermented excretion toxicant) are combined.
(24) In one variant, components for a Bactrocera (previously known as genus “Dacus”) dorsalis (Oriental fruit fly) lure comprise:
(25) TABLE-US-00001 1. bee's wax, by weight 36.4% 2. mineral oil, by weight 44.4% 3. ethyl methyl eugenol also known as methyl eugenol or lure, 11.5% by weight 4. spinosad, by weight 7.7%
(26) These proportions can be varied, to approximately these percentages.
(27) In a variant, the lure may be formed as follows. In a double boiler barely melt the wax. In a separate jar mix the lure with spinosad, watching the miscibility. As the wax melts add the mineral oil with an electric whisk type tool and mix very well beating in as much air as possible. As the mixture cools, notice a semi-hardening. As the wax/oil mixture is in the soft but hardening stage add the lure/spinosad whipping all ingredients together beating in as much air as possible. Keep beating until the mixture is too hard for your whisk to beat any more. Make sure that the whisk is moved all around to make the lure as homogenous as possible. Whisking and beating prevents premature volatilization of the mixture, allowing for a contaminated insects to carry it long enough to contaminate other insects that have not yet been contaminated. Let the mixture sit still until it settles which takes 12 to 24 hours. The finished lure should be a semi-solid compound that is light and fluffy, sticky, pliable, and rainproof. This is to allow for easy transmission from one insects to another.
(28) Other lures or lure combinations for other insets may be prepared utilizing the principles of the invention. For example, methyl eugenol also attracts Dacus zonatus which is another serious insect to be controlled by the present lure system.
(29) The following table 1 illustrates four example lure mixtures generated.

(31) In a second module 20, a cooling system is provided for eradicating insects from fruit. Fruit is isolated and kept isolated during a cooling system process, either with screening fine enough to exclude insects from re-infesting the fruit or in a sealed refrigerator type ocean going container or in a sealed refrigerated type building. If the cooling is done in a refrigerated shipping container then the doors would simply be sealed. If the cooling is done in a refrigerated type building then screening between the building's doorway and a sealable refrigerator type shipping container is placed in such a way to ensure that no insects could re-infest the fruit.
(32) In a variant, referring to
(33) In a step 215, measuring the soluble solids in the fruit. In addition, the total dissolved solids may be measured. Then, in a step 220, the relative freezing point of the fruit where ice crystallization will occur is computed.
(34) In a step 225, slowly acclimatize the fruit to chill by slowly changing the temperature.
(35) In a step 230, cooling the fruit down to a core temperature that is above the ice crystallization temperature, but below the freezing point of water, for about 31-36 hours or optionally the time period required for a-yet-to-be-USDA-APHIS approved sub-freezing quarantine protocol.
(36) In a step 235, slowly acclimatize the fruit by warming it up to shipping temperature, which may be 34-40 degrees Fahrenheit, similarly as in the cooling process.
(37) In another variant, referring to
(38) Package 310 fruit ready to be marketed in wholesale shipping boxes see e.g.
(39) For high brix produce in 24 to 48 hours, or optionally the time period required for a-yet-to-be-USDA-APHIS approved sub-freezing quarantine protocol, after attaining 26 to 31.5 degrees core temperature to be able to ship produce to otherwise prohibited quarantined markets. Currently approved cooling systems require 14 or 15 days at 34 degrees, which means there will be considerable fruit breakdown (also known as rotting) at destination. The present cooling treatment system will not work for low brix agricultural crops such as lettuce or zucchini.
(40) In another variant, the system cools the ambient air to between 26 degrees F. and 32 degrees F.
(41) In another variant, the Fruit Fly lure the comprises the following components for a Bactrocera (previously known as genus “Dacus”) dorsalis (Oriental fruit fly) lure:
(42) TABLE-US-00003 1. bee's wax, by weight 36.4% 2. mineral oil, by weight 44.4% 3. ethyl methyl eugenol also known as methyl eugenol or lure, 10.3% by weight 4. 1-octen-3-ol 0.12% 5. spinosad, by weight 7.7%
(43) These proportions can be varied about the number presented here.
(44) In a variant, a lure for attracting insects comprises: a wax; a wax thinning agent; a chemical lure; and a toxicant for insects. Optionally, the wax thinning agent is methyl eugenol. In another variant, the wax thinning agent is basil oil. In further variant, the lure comprises: a ratio of wax to wax thinning agent by weight of about 0.8188 to 1.0; a ratio of toxicant to wax thinning agent by weight of 0.0966 to 1.0; and 1 milliliter of toxicant per 5.65 grams of wax.
(45) A method of manufacturing lure comprises: In a double boiler barely melt the wax. In a separate jar mix the lure's attractant with spinosad watching the miscibility. As the wax melts add the mineral oil with an electric whisk/beater type tool and mix very well beating in as much air as possible. As the mixture cools notice a semi-hardening.
(46) As the wax/oil mixture is in the soft but hardening stage add the lure/Spinosad whipping all ingredients together beating in as much air as possible. Keep beating until the mixture is too hard the whisk. Ensure that the whisk is moved all around to make the lure is as homogenous as possible. Whisking and beating prevents premature volatilization of the mixture, allowing for a contaminated insects to carry it long enough to contaminate other insects that have not yet been contaminated. Let the mixture sit until it settles which takes 12 to 24 hours. The finished lure should be a semi-solid compound that is light and fluffy, sticky, pliable, and rainproof. This is to allow for easy transmission from one insects to another.
(47) There exists other lures, pheromones, or lure combinations for other insects. Methyl eugenol also attracts Dacus zonatus which is another serious insect to be controlled by our lure system. Trimedlure attracts the Mediterranean fruit fly with capilure acting something like an extender for Trimedlure. Ceratitislure is generally for Ceratitis cosyra, Questlure is for Ceratitus rosa as well as C. captita and C. cosyra. The ability of this base to control the volatilization of these various insect lures and toxicants is the overriding benefit of this invention which can be combined with a variety of lures/pheromones for targeted pest control.
(48) 1-OCTEN-3-OL may attract mosquitoes which can also be incorporated into the base.
(49) The lure/cooling system with various pheromones should control and allow new agricultural markets for areas with the following insects: 1. Ceratitis fruit flies 2. (Ceratitis capitata) (“medfly”) 3. Ceratitis rosa 4. Anastrepha fruit flies 5. Anastrepha fraterculus 6. A. suspensa in Florida 7. Mexican fruit fly (A. ludens) 8. Caribbean fruit fly (A. suspensa) 9. Mexican fruit fly and the West Indian fruit fly (A. oblique) 10. South American fruit fly (A. fraterculus) 11. Bactrocera fruit flies 12. melon fruit fly (B. cucurbitae) 13. Queensland fruit fly, B. tryoni 14. Oriental fruit fly (B. dorsalis) 15. guava fruit fly (B. correcta) 16. Philippines (B. philippinensis) 17. olive fruit fly (B. oleae) Bactrocera oleae (Gmelin) 18. Other species that presently assigned to the Dacus genus that in the future may be reassigned to the genus Bactrocera or other genera, may also be controlled by the system of the present invention.
(50) A novelty of the lure system of the present invention is to control volatilization of lure/toxicant, rain or shine, and that the pests see it as a food, eating it along with the toxicant and exposing new lure/toxicant while eating, killing that pest and preparing a location for the attraction of the next pest. Below is a partial list of insects that can be controlled with this system in Table 2.

(120) The insect control system of the present invention has the following advantages:
(121) The lure system base controls the volatilization in rain or shine of the both the toxicant and the pheromone.
(122) The target insects actually see the lure as food and eats some of the lure.
(123) When the target insect eats some of the lure then that opens up new bubbles of lure/toxicant to attract the next attracted insect.
(124) For most insects in their mating ritual, the male feeds the female. Thus, if one uses a relatively slow acting poison then the insects feed each other the lure/toxicant, killing many more than otherwise would come to the lure. During copulation ritual intimate physical contact with a contaminated individual is another transmission vector.
(125) The lure system is presently certified for use in organically grown farming systems.
(126) The lure system can utilize cheaper non-organically approved toxicants.
(127) The system has at least a four month effective life.
(128) The cooling system uses neither chemicals nor radiation and causes no detectable damage to the fruit but kills insects to open new markets.
(129) Rather than heat up agricultural products to kill insects and then cool the fruit rapidly which does change the crop or product and costs a lot of energy the system of the present invention cools the crop or product down at or a little below freezing. The fruits' soluble solids act as anti-freeze similar to in a car's cooling system to lower the freezing temperature.
