A topical insect repellent with extended duration of protection was obtained from mixtures of molecules based on two or more volatile repellent organic molecular species occurring naturally on the human skin surface. The novel repellent comprises mixtures of lower, intermediate, and higher volatility organic molecules. Active ingredients for formulations are obtained from homologous series of carboxylic acids, alcohols, ketones, and lactones which span a similar range of volatility and which occur naturally on the skin surface. Volatile silicone fluid imparts mildness and water repellency to the repellent formulations. The new natural repellent exhibits the longevity and repellency that is comparable to N,N-diethyl-m-toluamide (DEET), a synthetic compound employed in almost all commercial formulations, but the inventive natural repellent is more acceptable than DEET, which has an unpleasant odor and imparts a greasy feel to the skin. The inventive insect repellent, formulated in a volatile silicone fluid, was shown to repel and incapacitate stable flies. This finding demonstrated that repellency was not limited to mosquitoes, but extends to other biting flies or insects, thus demonstrating the utility of the novel insect repellent for protecting pets and livestock as well as humans.

Embodiments of the present disclosure can provide an automated mass rearing system for insect larvae. The automated mass rearing system can facilitate hatching, feeding, monitoring the growth and emergence of insect larvae and pupae. In some embodiments, the automated mass rearing system can include a production unit, a transportation unit, a storage unit, a dispensing unit, and a monitoring unit. In some embodiments, this automated mass rearing system can facilitate mass mosquito growth from egg hatching all the way through to full adults or certain stages in between such as the larvae rearing process (i.e., from larvae to pupae) with little or no human intervention. By automating the rearing and transportation of insect eggs, larvae, and pupae, deaths or developmental issues can be minimized. Various techniques and apparatuses are used in this automation that causes minimal disturbance to the insects during development, and thereby maximizing survival rate and fitness of the insects.

A drone with a high-voltage trap seeks, identifies, pursues and destroys flying insects within a patrolling area. During its passive attracting mode, the drone lands on a designated ground site and attracts insects with light, sound, and scents. Once insects are lured, the high voltage screens trap will immediately electrocute targeted insects. In its active offensive mode, the drone hovers closer to insect nests using its high-velocity propellers, producing strong downdraft jet streams to disturb the nest and force insects, such as mosquitoes and the like, to evacuate their nest. Once insects are airborne, the drone pursues fleeing insects from below or behind, making use of its propellers and vacuuming the fleeing insects. Slow flying insects that come in contact with the high-voltage electrified screens are immediately electrocuted. Insects that are vacuumed into the fast-spinning propellers blades are knocked down and killed. A rectified charging pad recharges the drone batteries.

The invention discloses a long-acting insect expelling carrier. Carboxylic acid and derivatives thereof, essential oil and the like are prepared into an insect expelling composition, and then the insect expelling composition is prepared into the insect expelling carrier which violates insect expelling components long effectively by a two-step addition method. Long scarves, kerchiefs, muffles, jewelry, tablemats, appliques, silk flowers, artificial flower green leaves, cross-stitch embroidery, glass holders, dolls, embroidery, wall maps, tapestries, curtains, mosquito nets, ornaments and the like prepared from the insect expelling carrier can effectively expel various pests such as aphids, leafhoppers, cockroaches, ants, acarid, mosquitoes, biting midges, flies and the like, and prevent thepests positively; and the use of sprayed or fumigated pesticides is reduced, and the long-acting insect expelling carrier has important significance for environmental protection and human health, andhas good application prospect due to the characteristics of long effectiveness and convenient use.

One or a combination of known chemical cues that attract pregnant female mosquitoes to an egg-laying site are embedded in a biodegradable carrier that releases the compound at a generally constant rate for up to a year or longer. The compound is useful for attracting large numbers of mosquito vectors to a site where they and their progeny can be eliminated.

An apparatus for attracting mosquitoes to an electronic insect killing machine (i.e., bug zapper) is provided. The apparatus includes a converter device that fits over a fluorescent or ultraviolet light bulb of the bug zapper. The converter device controls radiant light and heat emitted by the light bulb to produce a desired level of heat to create a warm mass, or host simulator that simulates a blood host meal for biting insects. Mosquitoes and other biting insects, which have infrared vision, are attracted to the host simulator. When used with a scented lure that lures the mosquitoes and biting insects near the insect killer, the host simulator lures the mosquitoes and other insects to the killing device of the insect killer. The mosquitoes and biting insects are destroyed once lured to the killing device. The converter device also blocks most of the visible light emitted by the light bulb, and therefore does not lure beneficial insects, which are attracted to visible light, into the insect killer.
