Problems solved by technology

[0004] At present, the active ingredients of most fly baits and cockroach baits are single doses, and the mechanism of action is single. Long-term application is prone to metabolic resistance and target site mutations, resulting in failure of on-site application control

Abstract

The invention provides a hygienic insecticidal composition, the active ingredients are propoxur and acetamiprid; the mass ratio of propoxur and acetamiprid is 10:1-1:10; the active ingredients are contained in the composition The content of is 0.01‑5wt%. The control objects of the hygienic insecticidal composition are ants, cockroaches and flies. The present invention also provides a matrix that can be used for the above-mentioned insecticidal gel bait. The bait of the present invention adopts two kinds of active ingredients with different action mechanisms, mixed in an appropriate proportion, the action effect is obviously synergistic compared with a single agent, can effectively prevent and control resistant pests, and delay the occurrence and development of drug resistance; and The skin irritation caused by pyrethroid agents can be avoided, and the safety is high. The bait matrix provided by the invention has suitable viscosity and hardness, and can be applied to extruded products; it has a good moisturizing effect, does not become moldy or hard after being placed for a long time, can increase the interval between spraying, and can be widely used in various baits Dosage preparation.

Description

technical field [0001] The invention belongs to the field of hygienic insecticides and relates to a hygienic insecticide composition containing propoxur and acetamiprid. Background technique [0002] Acetamiprid belongs to chlorinated nicotinic insecticides. It has contact killing, stomach toxicity and strong penetration. It acts on the nicotinic acetylcholine receptors at the synapses of the insect nervous system, interferes with the stimulation conduction of the insect nervous system, and causes nerve damage. Blockage of systemic pathways results in the accumulation of the neurotransmitter acetylcholine at synaptic sites, leading to paralysis and eventual death of the insect. Based on its special mechanism of action, acetamiprid can effectively kill sanitary pests resistant to organochlorines, organophosphates, carbamates and pyrethroids. [0003] Proxacarb is a carbamate insecticide, which inhibits the activity of acetylcholinease in the central nervous system and periph...
