Embodiment 1

[0093] Example 1-dried residue insecticidal activity

[0094] Using isopropyl alcohol (isopropanol) as a carrier diluent, a preparation containing 5.5% by weight neem oil, 15.5% by weight acetophenone, 8% by weight natural oils (lemongrass oil, spearmint oil, clove oil) and wintergreen oil), and 5.0% by weight of ethoxylated castor oil in 'Solution A'. A series of dilutions were made including 100% Solution A, 50% Solution A in isopropanol, 25% Solution A in isopropanol, and 10% Solution A in isopropanol. 1.0 mL of each solution was applied to 90-mm filter paper bases in petri dishes. The substrates were allowed to air dry for two hours and then infested with adult bed bugs (approximately half male and half female). The same experiments for each treatment group and negative control group were tested simultaneously. Mortality was observed at indicated time intervals after infestation. Adult bedbugs were counted dead if they were unresponsive when stimulated.

[0095] The p...

Embodiment 2

[0098]Example 2 - Dry Residue Insecticide Activity of Various Insecticidal Natural Oils

[0099] This example illustrates the insecticidal activity of dry residue of formulations containing various insecticidal natural oils as active ingredients. By adding 2.5% by weight of insecticidal natural oil as active ingredient, 2.5% by weight of sodium lauryl sulfate, 5.0% by weight of solvent (such as ethyl lactate or acetophenone as recorded) and an appropriate amount of water as diluent Combine to prepare a solution. 1.0 mL of each solution was applied to three replicates containing 90 mm diameter filter paper in Petri dishes (treatment groups). Three identical samples of the treated and untreated controls were allowed to dry for two hours prior to infestation with a known number of adult bedbugs (approximately half male and half female).

[0100] Bed bug mortality was assessed daily immediately post-infestation and at time intervals of 2, 4, 8, 12 and 24 hours post-infestation, ...

Embodiment 3

[0105] The insecticidal activity of dry residue of embodiment 3-multiple solvents

[0106] This example illustrates the insecticidal activity of dry residue of formulations comprising neem oil and various organic solvents including alcohols, ketones, esters and carboxylic acids. Solutions were prepared using: 5.5% by weight of neem oil; the weight percent of organic solvent given in Table 5 and an appropriate amount of isopropanol as a carrier diluent. The weight percent of each solvent was varied to ensure a consistent molar amount of solvent in each solution (final concentration of 1.5 mol / kg). Treatment groups for each solution were prepared by treating a 90 mm diameter filter paper with 1.0 mL of the solution and allowing it to air dry for four hours. Four hours after treatment, a known number of adults was added to each treated dish. Bedbug mortality was assessed immediately after infestation and at intervals of 1 hour, 2 hours, 4 hours, 6 hours, 8 hours, 10 hours, 12 h...

Abstract

Compositions useful for controlling pests are disclosed. In some embodiments, the composition includes a pesticidal natural oil and a polar aromatic solvent. Methods of making and using the compositions are disclosed.

Description

technical field [0001] Some embodiments of the present invention relate to compositions useful for controlling (controlling) various pests. Some embodiments of the present invention can be used to control arthropods (including insects and arachnids), and / or other pests. Some embodiments of the present invention are useful for controlling sucking and biting pests including, for example, bedbugs, mosquitoes, ticks, lice, stinkbugs, flies, cockroaches, and moths. Some embodiments of the invention relate to methods of controlling pests using the compositions. Other embodiments of the invention relate to methods of making compositions for controlling pests. Background technique [0002] Pest control is a current worldwide problem. In addition to the physical means of control that have been practiced for centuries, recent decades have seen the emergence and widespread use of hundreds of chemically developed repellants, growth regulators, and insecticides. Prior to commercializ...
