Abstract
The invention discloses a method of using sex pheromone isotropic agents to prevent and cure adelphocoris suturails and adelphocoris taeniophorus and belongs to the technical field of agricultural insect prevention and cure. The method of using the sex pheromone isotropic agents to prevent and cure the adelphocoris suturails and the adelphocoris taeniophorus is a new method which can prevent and cure the adelphocoris suturails and the adelphocoris taeniophorus by using butyric acid hexylester which is the main ingredients of artificially synthesized sex pheromone of the adelphocoris suturails and the adelphocoris taeniophorus and interfering the transmission of mating information of male and female adelphocoris suturails and the adelphocoris taeniophorus. The method is suitable for the comprehensive prevention and cure of the domestic adelphocoris suturails. The mating rate can be reduced more than 80% after an isotropic agent device is provided. The isotropic agents of the method of using the sex pheromone isotropic agents to prevent and cure the adelphocoris suturails and the adelphocoris taeniophorus are strong in specificity, raw materials of a releasing device can be obtained easily and is easy to operate, influence of natural conditions is small, interference mating ability is strong and lasting period is long.
Description
Technical field
The invention belongs to agricultural insect pests control technical field, be specifically related to the method for isotropic dose of a kind of usability pheromones control black striped plant bug and adelphocoris taeniophorus.
Background technology
Black striped plant bug Adelphocoris suturalis Jakovlev and adelphocoris taeniophorus Adelphocoris fasciaticollis Reuter all belongs to Semiptera Hemiptera, Miridae Miridae, extensively distribute from south to north in China, be Cotton in China produce on a kind of important pests.Its plasmodium cynomolgi is mixed, and host plant, except cotton, also comprises more than 80 Plants such as pulse family, Amaranthaceae, Solanaceae, composite family, the vegetables that wherein a lot of Dou Shi China is important and fruit crop.Black striped plant bug and adelphocoris taeniophorus like phytophagous meristematic tissue, especially tender leaf, flower, young fruit, a large amount of holes of leaf one-tenth after its thorn is inhaled, and fruit forms malformed fruit and tertia fruit, has a strong impact on the yield and quality of crop.
Middle and later periods the 90's of 20th century, along with popularizing rapidly of transgenic cotton against pests, cotton field Pesticide use amount die-offs, thus causes belonging to the double cotton field minor pests such as black striped plant bug and adelphocoris taeniophorus controlling object originally and rise to primary pest.On the other hand, under the background of the adjustment of China's agricultural planting structure, veterinary antibiotics cultivated area increases sharply, for black striped plant bug and adelphocoris taeniophorus etc. provide vector and hibernacle, exacerbate the catastrophic outburst of fleahopper, become the Severe pests of the multiple Important Economic crops such as Cotton in China, jujube, grape and cherry.
Current China is also in the starting stage for the control of fleahopper and mainly relies on chemical control, and cultural control, physical control and biological control application are seldom.A large amount of uses of chemical pesticide, make the Detection of insecticide resistance of black striped plant bug and adelphocoris taeniophorus high, continue to increase Pesticide use amount and have been difficult to deal with problems, and can bring various environmental problem.Simultaneously under the prerequisite of current promotion environmental protection, non-environmental pollution control, utilizing semiochemical in black striped plant bug and adelphocoris taeniophorus kind to regulate and control its mating behavior to reach control efficiency is a kind of ideal insect protected new technology.Utilize the most effective method of pheromone control insect to be Mating discruption, i.e. chemical communication between usability pheromones class material blocking-up, interference male and female, reduces its mating rate, reduces insect progeny size.
Summary of the invention
One is the object of the present invention is to provide to utilize black striped plant bug and adelphocoris taeniophorus sex pheromone component as isotropic dose, for the black fleahopper in Insect pest suppression control and adelphocoris taeniophorus method.
The method of usability pheromones is isotropic dose control black striped plant bug and adelphocoris taeniophorus, comprises step as follows:
(1) preparation of isotropic dose of releasing device: using n-hexyl butyrate as isotropic dose, is loaded in the pvc pipe as delayed release device, and useful load is 5-15mg, then by pvc pipe sealing two ends, obtains isotropic dose of releasing device;
(2) be fixed on crop by isotropic dose of releasing device, evenly arrange in field, isotropic dose of releasing device quantity of per hectare deployment is 300-800/hectare.
N-hexyl butyrate is released slowly into field by pvc pipe, when the n-hexyl butyrate amount scattered in the air of field acquires a certain degree, can reach interference and block chemical communication in black striped plant bug and adelphocoris taeniophorus kind, reduce its mating rate, reduce the object of its population quantity.
Test shows, the method that black striped plant bug and adelphocoris taeniophorus isotropic dose of Insect pest suppression prevent and treat black striped plant bug and adelphocoris taeniophorus is simple, preventive effect is given prominence to, and can reduce the mating rate of black striped plant bug and adelphocoris taeniophorus 80%, and long-term release black striped plant bug and adelphocoris taeniophorus population quantity can reduce by more than 80%; And good stability, the lasting period is long, and the PVC capillary releasing device lasting period can reach 100-150 days.
The beneficial effect of method of the present invention is: isotropic dose of selectivity in the method is strong, on natural enemy without impact; Releasing device raw material is easy to get, simple possible; Little by effect of natural conditions; Insect pest suppression ability is strong; The feature that lasting period is long, preventive effect is given prominence to, and can reduce the mating rate of black striped plant bug and adelphocoris taeniophorus 80%, and long-term release black striped plant bug and adelphocoris taeniophorus population quantity can reduce by more than 80%; And good stability, the lasting period is long, and the PVC capillary releasing device lasting period can reach 100-150 days.
Embodiment
Embodiment 1
Release time using n-hexyl butyrate as isotropic dose measures
The 10% chlorinated paraffin wax solution containing 5mg n-hexyl butyrate is put into the bottle placement of polyethylene (PVC) after 3 months, by gas chromatographic detection, n-hexyl butyrate remains 50%.
Embodiment 2
The preparation of isotropic dose of releasing device
Adopt conventional pvc pipe, pvc pipe internal diameter 0.5-1mm, wall thickness is about 0.05mm, the 10% chlorinated paraffin wax solution containing 5-15mg n-hexyl butyrate is injected in pvc pipe, and adding 1-5mg 2,6-di-tert-butyl-4-methy phenol (BHT) or vitamin E, sealing two ends is as isotropic dose of releasing device.
Embodiment 3
The plot that test site selects black striped plant bug and adelphocoris taeniophorus to break out simultaneously, releasing device embodiment 2 prepared directly is wound around or is fixed on crop branch with fine rule, the anti-pheromones releasing device quantity 300-800 of per hectare deployment is individual, places and detects after 30 days.
N-hexyl butyrate is released slowly into field by tube wall, when the n-hexyl butyrate amount scattered in the air of field acquires a certain degree, can reach interference and block chemical communication in black striped plant bug and adelphocoris taeniophorus kind, reduce its mating rate, reduce the object of its population quantity.
Wherein isotropic dose of releasing device concrete consumption and place that quantity is each arranges 3 repetition, suppress mating rate to be taken the mean, the concrete consumption of isotropic dose of releasing device and place quantitative example and suppression mating rate effect thereof as shown in table 1, table 2.
