Embodiment 1

[0063] Extraction of Cockroach Aggregation Pheromone

[0064] Take cockroach nymphs from 7th instar to 3 days old and place cockroach adults in a breeding box for 5 days, collect cockroach feces, dissect all cockroaches and take their midguts, grind and mash them, and add anhydrous water at a ratio of 1:1.5 after weighing Ethanol, extracted by Soxhlet extraction for 8 hours, and filtered to obtain the extract, which has a strong urine smell. Store in -4°C refrigerator.

Embodiment 2

[0066] Extraction of Cockroach Aggregation Pheromone

[0067] Take cockroach nymphs from 7th instar to 3 days old cockroach adults and place them in a breeding box for 10 days, collect cockroach feces, dissect all cockroaches, take their midguts, grind and mash them, and add anhydrous water at a ratio of 1:2.5 after weighing Ethanol, extracted by Soxhlet extraction for 5 hours, filtered to obtain the extract, which has a strong smell of urine. Store in -4°C refrigerator.

Embodiment 3

[0069] Follow the steps below to prepare cockroach-killing gel bait

[0070] 1) Heating the jelly to melt it to obtain a jelly liquid, keeping it warm for later use;

[0071] 2) Add glucose, sorbitol, maltodextrin, azone and sodium benzoate to the jelly solution to dissolve, and finally add Carbomer 940, soak for 20 minutes, and keep the temperature of the mixed solution at 40°C after soaking;

[0072] 3) Add triethanolamine, stir for 10 minutes to obtain a paste, then add melted butter, stir for 10 minutes and homogenize for 1 minute;

[0073] 4) Add cooked flour, stir for 10 minutes and homogenize for 1 minute, then cool;

[0074] 5) Add fipronil and the cockroach pheromone prepared in Example 1, stir for 10 minutes and homogenize for 1 minute to obtain the cockroach-killing gel bait, wherein fipronil or its derivatives are formulated to 3% before feeding. D98≤5μm of the suspending agent.

[0075] Wherein, the addition amount of each component is:

[0076] Fipronil or it...

Abstract

The invention provides a method for extracting cockroach gathering pheromone. The method comprises the steps of feeding the cockroaches for 5-10 days, disecting midguts of the cockroaches, grinding and triturating the midgets together with feces of the cockroaches, adding 1.5-2.5 fold amounts of an organic solvent, carrying out extraction for 5-8 hours by virtue of a Soxhlet extraction method, and filtering, so as to obtain an extract. The invention further provides cockroach-killing gel bait. The cockroach-killing gel bait comprises the following components in parts by weight: 0.01-0.5 part of fipronil or a fipronil derivative, 0.05-0.5 part of the cockroach gathering pheromone, 5-30 parts of glucose syrup, 5-30 parts of sorbitol, 1-15 parts of butter, 1-15 parts of cooked flour, 1-10 parts of maltodextrin, 0.5-10 parts of azone, 0.3-2 parts of Carbopol 940, 0.3-2 parts of triethanolamine, 0.1-1.5 parts of sodium benzoate and 30-60 parts of jelly. The invention further provides a preparation method of the cockroach-killing gel bait.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a method for extracting cockroach aggregation pheromones, a cockroach-killing gel bait and a preparation method thereof. Background technique [0002] Cockroaches are worldwide important sanitary pests, polluting food, infecting diseases, and seriously threatening human health. Due to convenient transportation and suitable indoor temperature and humidity, cockroaches are basically covered in any place except the Arctic and Antarctic. Cockroaches reproduce rapidly, have strong ability to resist external damage, and have strong concealment ability at the same time, so it is difficult to eradicate cockroaches. [0003] At present, the main dosage forms of cockroach control include suspension concentrate, microcapsule suspension concentrate, emulsifiable concentrate, water emulsion, granule and gel bait. Although they can all control cockroaches, each has its own advantages and disadvantag...
