System for trapping flying insects with attractant lures
View Patent ↗The present application discloses a system for trapping flying insects, utilizing carbon dioxide in conjunction with one or more biochemical lures, visual lures or both. Preferably, a biochemical lure such as lactic acid, a salt of lactic acid, or combinations thereof, are employed in particular geometric shapes contained in specifically designed housing to ensure an effective release rate over extended periods of time.
1. A device comprising a trap chamber for collecting insects, an inlet communicating with the trap chamber, and an airflow generator constructed to draw air into the trap chamber via the inlet so that insects proximate to the inlet are drawn in the trap chamber; and at least one lure for attracting insects to the device wherein the lure comprises a lactic-acid gel and a water gel, wherein
a) the lactic-acid gel comprises:
(i) 20 wt. % to 50 wt. % sodium acrylate;
(ii) 50 wt. % to 75 wt. % L-(+)-lactic acid;
(iii) 1 wt. % to 5 wt. % polyethylene glycol 600 diacrylate; and
(iv) 1 wt. % to 3 wt. % phosphine oxide; and
b) the water gel comprises:
(i) 30 wt. % to 70 wt. % sodium acrylate;
(ii) 2 wt. % to 6 wt. % L-(+)-lactic acid;
(iii) 1 wt. % to 5 wt. % polyethylene glycol 600 diacrylate;
(iv) 0.5 wt. % to 2 wt. % phosphine oxide; and
(v) 30 wt. % to 70 wt. % distilled water.
2. The device according to claim 1 , wherein:
a) the lactic-acid gel comprises:
(i) 37.0 wt. % sodium acrylate;
(ii) 59.6 wt. % L-(+)-lactic acid;
(iii) 2.4 wt. % polyethylene glycol 600 diacrylate;
(iv) 1.0 wt. % phosphine oxide; and
b) the water gel comprises:
(i) 47.0 wt. % sodium acrylate;
(ii) 3.4 wt. % L-(+)-lactic acid;
(iii) 3.4 wt. % polyethylene glycol 600 diacrylate;
(iv) 1.2 wt. % phosphine oxide; and
(v) 45.0 wt. % distilled water.
3. The device according to claim 1 , wherein the lure is engineered, configured, or positioned within the device to controllably release lactic acid.
4. The device according to claim 3 , wherein the release is at a rate of about 2.0 mg/hr to about 20 mg/hr into CO 2 exhaust.
5. The device according to claim 1 , wherein the lure is incorporated into a cartridge.
6. The device according to claim 5 , wherein the cartridge further comprises at least one hole.
7. The device according to claim 6 , wherein the hole has a diameter ranging from about 0.05 inch to about 0.25 inch.
8. The device according to claim 7 , wherein the diameter ranges from about 0.1 inch to about 0.2 inch.
9. The device according to claim 8 , wherein the diameter is about 0.14 inch.
10. The device according to claim 1 , wherein the lure, when contacted with a steady flow of air at a temperature of about 90° F., releases from about 1.0 to about 35 mg/hr of lactic acid, for a period of about two weeks.
11. The device according to claim 1 , wherein the lactic-acid gel is adjacent to the water gel.
12. The device according to claim 1 , wherein a lactic acid in the lactic-acid gel is not chemically bonded to the gelling network of the lactic-acid gel.
13. The device according to claim 1 , wherein the water in a water gel is not chemically bonded to the gelling network of the water gel.
14. The device according to claim 1 , wherein the lactic-acid gel further comprises a UV-reactive compound.
15. The device according to claim 1 , wherein the water gel further comprises a UV-reactive compound.
16. The device according to claim 1 , wherein the lactic acid in the lactic-acid gel is L(+)-lactic acid.
17. The device according to claim 14 , wherein the UV-reactive compound is acrylic acid or a salt of acrylic acid.
18. The device according to of claim 15 , wherein the UV-reactive compound is acrylic acid or a salt of acrylic acid.
19. The device according to claim 1 , wherein the lactic-acid gel and/or the water gel further comprise a photo-initiator.
20. The device according to claim 1 , wherein the lactic-acid gel and/or the water gel further comprise a cross-linking agent.
