Abstract
The present invention relates to field of pest control, a kind of fast-acting insecticide for lepidoptera pest adult is specifically provided.The insecticide is that the content of Rynaxypyr in the food lure containing Rynaxypyr, the insecticide is 1~100mg/L.Its, quick-acting high to bollworm and prodenia litura virulence is good, and to non-target organism and Environmental security.
Description
Technical field
The present invention relates to field of pest control, specifically, it is related to a kind of quick-acting desinsections for lepidoptera pest adult
Agent.
Background technology
Bollworm [Helicoverpa armigera (H ü bner)] and prodenia litura [Spodoptera litura
(Fabricius)] belong to Lepidoptera Noctuidae, be worldwide important agricultural insect, not only influence grain, vegetables and industrial crops
Yield, can also cause its quality decline.
At present, chemical prevention is still the important means for controlling two kinds of insects, because bollworm and prodenia litura are insect state
Predominantly larva, so, past prevention and controls are to carry out spraying preventing and treating for its larva or ovum.However, with pesticide resistance
Generation, force peasant to be continuously increased dosage and carry out pest control, it is serious to threaten agricultural product and ecological environment security.
The volatile matter that host plant produces is played an important role during plant-feed insect finds host.Phytophagous
The volatile matter that insect can be discharged using host plant instructs its host location behavior, so as to correctly find its host plant
Thing.Lepidopterous insects adult flies, sought a spouse for satisfaction, reproduction largely supplements the nutrients to the demand needs of energy, is waved by plant
Stimulating food and attractant compound mixture efficient pesticides based on its design make food lure, trap and kill the squama such as bollworm and prodenia litura
Wing mesh adult pest, new approach is provided for its preventing and treating.This method can largely reduce the spraying consumption of insecticide, reduce desinsection
The residual risk of agent.
However, being found that many problems in food lure application process：(1) to the efficient insecticide of lepidoptera pest adult
After considerably less (Socorro et al., 2010), imago feeding food lure control action not substantially, survival can also be continued；(2) one
A little medicaments are good to the virulence effect of adult, but quick-acting is bad, can also continue egg reproduction after taking food within a period of time, and then
Bring the occurrence injury of offspring larva；(3) after imago feeding quick-acting bad medicament, moreover it is possible to continue to fly between crop and expand
Dissipate, the agricultural chemicals adhered on polypide is taken on crop, bring the residues of pesticides excessive problem of the agricultural product such as fruits and vegetables；(4) eat
The toxicity of pesticide such as Methomyl in the past conventional is high in lure, is easily caused agricultural product edible safety problem.
Accordingly, it would be desirable to screen efficient to lepidoptera pest adult, quick-acting, while the insecticide species of green safety, and grind
Its combined use technology that lure is eaten in lepidoptera pest is sent out, the innoxious prevention and control and agriculture of great lepidoptera pest adult are promoted
The green production of crop.
The content of the invention
In order to solve problems of the prior art, it is used for lepidoptera pest adult it is an object of the invention to provide one kind
Fast-acting insecticide.
In order to realize the object of the invention, present invention firstly provides a kind of fast-acting insecticide for lepidoptera pest adult,
The insecticide is the food lure containing Rynaxypyr.
Further, the food lure is the food lure of bollworm and/or prodenia litura adult, concretely noctuid profit it
Plain bait formulation.
Preferably, the food lure, which is bollworm, eats the composition that lure eats lure with prodenia litura adult.
Further, in the insecticide Rynaxypyr content be 1~100mg/L, prioritizing selection 50~
100mg/L。
The lepidoptera pest is bollworm, prodenia litura and its sibling species class.
Present invention also offers application of the Rynaxypyr in preventing and treating lepidoptera pest adult.
In the application, lepidoptera pest is bollworm, prodenia litura and its sibling species class.
Further, the application is to mix Rynaxypyr and the food lure of bollworm and/or prodenia litura adult
Close, the food lure containing 1~100mg/L Rynaxypyrs is made, the food lure containing Rynaxypyr is placed on trapping
On device, its bottom position concordant with crop top is suspended on, lepidoptera pest is trapped and killed.
The beneficial effects of the present invention are：
The invention provides the valid density that Rynaxypyr prevents and treats lepidoptera pest adult, and contain there is provided one kind
The fast-acting insecticide of Rynaxypyr, its, quick-acting high to bollworm and prodenia litura virulence is good, and to non-target organism and
Environmental security.
Embodiment
Following examples are used to illustrate the present invention, but are not limited to the scope of the present invention.
The preparation of the fast-acting insecticide of embodiment 1
Following examples are used to illustrate the present invention, but are not limited to the scope of the present invention.
1st, raw material：
Rynaxypyr (95%, E.I.Du Pont Company (Shanghai)), food lure (Australia's Pola, the Le Bao biological husbantries section of Shenzhen hundred
Skill Co., Ltd)
2nd, preparation method：
100mg Rynaxypyrs are dissolved into 1L food lures, Rynaxypyr content killing for 100mg/L is obtained
Worm agent.
The preparation of the fast-acting insecticide of embodiment 2
The present embodiment and the difference of embodiment 1 are：1mg Rynaxypyrs are dissolved into 1L food lures, chlorine is obtained
Worm benzamide content is 1mg/L insecticide.
The virulence experiment of the Rynaxypyr of embodiment 3
Toxicity test chooses 3-5 ages in days adult and moves into plastic cup (upper bore 68mm, height using malicious nutrient solution method is fed
74mm, bottom 48mm) in, by dipped hydromel or the cotton balls of the hydromel of Rynaxypyr containing various concentrations, respectively as cotton boll
The supplement foodstuff of worm or prodenia litura adult is put into plastic cup, and often pipe loads 2 adults, often handles 10 adults, repeats 3
It is secondary, inspection result after 24h, it is impossible to which normal flight is designated as death.
Table 1：(100mg/L) is to bollworm adult virulence during 15 26 kinds of insecticide high concentrations of class
15 26 kinds of class insecticides show the toxicity test result of bollworm adult, for examination diamide (chlorine worm benzoyl
Amine, fipronil bisamide), carbamates (Methomyl, thiodicarb and indoxacarb), Avermectins (AVM), big ring
