Description
Technical Field
The invention belongs to the field of pest control, and particularly relates to a sex pheromone attractant for oriental arborvitae pine caterpillars.
Background
The oriental arborvitae pine moth (Dendrolimus subsitus, Lajonquieree) belongs to Lepidoptera (Lepidotera) and Lasiocapidaceae (Lasiocapidae) and is a main pest of trees in the Pinaceae, tender buds and needle leaves are eaten by larvae, and in severe cases, the needle leaves can be completely eaten, so that the trees are difficult to recover normal growth, and the whole forest is in a withered yellow state. The insect is mainly distributed in provinces such as Shanxi, Shaanxi, Hebei, inner Mongolia and Henan of China, and early reports on the prevention and control of the insect are as follows: the prevention and control means of picking up worm eggs manually, using black light lamps, applying beauveria bassiana powder guns, spraying pesticide pyrethrin and the like are all focused on killing pests after outbreak, the quantity of the pine moth pests in the group is large, the damage spread is rapid, and pine trees are often distributed in remote and sparsely populated forest areas, so that the monitoring means of rapidness, accuracy, convenient use and low cost is important in the prevention and control of the pests.
The insect sex pheromone can cause chemical substances which can generate sexual behavior reaction of the same sex of insects, has important effects on adjusting reproduction and multiplication of the insects and controlling population density, has the advantages of high efficiency, no toxicity, no pollution, safety to natural enemies and the like when being used for preventing and controlling the pests, and has wide prospect on the premise of having the smallest influence on the ecological environment. At present, more than 1000 kinds of insect sex pheromones or analogues are identified all over the world, tens of millions of hectares of agricultural crops and forest areas use sex pheromone products for pest control, and more than 100 kinds of sex pheromone products are put into use in China. The sex pheromone of female moth has different composition and proportion and species specificity, i.e. the sex pheromone structures of different geographic populations are different and the sex pheromone structures of the related species are also different. During the whole process, the pheromone binding proteins have a selective filtration action, expressed as a selective action on pheromones, whereas they do not bind on non-pheromone odours and are selective for individual components of a pheromone mixture. The high degree of specificity of the insect sex pheromone communication system determines that different species of insects have different sex pheromone compositions and proportions that are the basis for the insects to complete population reproduction and thereby form reproductive isolation from the sibling species. The identification of insect sex pheromone components is thus a prerequisite for the use of sex pheromones for the control of pests. Therefore, the biological characteristics and the physicochemical control of the oriental arborvitae pine caterpillar are reported at present, but the sex pheromone component of the oriental arborvitae pine caterpillar is not reported at home and abroad.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides the oriental arborvitae pine caterpillar sex pheromone attractant, which solves the problem of prevention and control of the oriental arborvitae pine caterpillar, can be used for insect condition prediction, mating interference or mass trapping of the oriental arborvitae pine caterpillar, and has the advantages of high efficiency, no toxicity, no pollution, low cost and convenient use.
The purpose of the invention is realized by the following technical scheme:
the oriental arborvitae pine moth pheromone attractant is characterized by comprising effective components and a solvent, wherein the effective components in the attractant are as follows: trans-5-trans-7-dodecadienol, cis-7-dodecadienol acetate, trans-5-trans-7-dodecadienol acetate and trans-5-trans-7-dodecadienol aldehyde, wherein the four components are a mixture of any two or more than two of the components except the combination of the cis-7-dodecadienol acetate and the trans-5-trans-7-dodecadienol aldehyde.
Furthermore, the effective components of the attractant are a mixture of four components of trans-5-trans-7-dodecadienol, cis-7-dodecadienol acetate, trans-5-trans-7-dodecadienol acetate and trans-5-trans-7-dodecadienol aldehyde.
Further, the weight parts of the active ingredients of the attractant are as follows: trans-5-trans-7-dodecadienol 40-50; 20-30 parts of cis-7-dodecenyl enol acetate; trans-5-trans-7-dodecadienol acetate 10-20; trans-5-trans-7-dodecadienal 5-12.
Further, the solvent is petroleum ether or n-hexane, and the effective component accounts for 1.5% of the solvent in parts by weight.
Furthermore, the preparation method of the attractant is to mix and dissolve the effective components and the solvent.
Further, the attractant also comprises an antioxidant, the antioxidant is one or a mixture of 2, 6-di-tert-butyl-p-cresol, butyl hydroxyanisole and natural vitamin E, and the weight ratio of the effective components to the antioxidant is 1: 0.02-0.05.
The invention has the beneficial effects that: the oriental arborvitae pine moth pheromone attractant is formed by repeated tests in laboratories and forests, is favorable for protecting natural enemies whether being used for insect condition observation or trapping or interfering mating in a large quantity, avoids using chemical pesticides, is environment-friendly and safe, is convenient to use, has low cost and long validity period, can achieve the aim of effectively preventing and controlling oriental arborvitae pine moths, and has obvious ecological benefit and economic benefit.
Monitoring insect pest situation: the oriental arborvitae pine moth provided by the invention can be used for monitoring pest situation, and the occurrence and growth condition of the oriental arborvitae pine moth in forests can be timely and accurately known through adult trapping condition, so that a scientific basis is provided for timely and effective prevention and control. The sex pheromone attractant composition provided by the invention can be used for detecting and reporting insect situations, and is high in sensitivity and strong in specificity.
Mass trapping: according to the insect condition monitoring result, the oriental arborvitae pine moth sex pheromone attractant composition provided by the invention is prepared into an attracting core to be hung in a victim arborvitae forest during the eclosion mating period of the oriental arborvitae pine moth, male insects mating in the mating period between the forests are attracted and killed as soon as possible, the proportion of female insects and male insects is seriously imbalanced, and the mating chance of the female insects is reduced, so that the insect population density of filial generations of the male insects is greatly reduced, the purpose of reducing harm is achieved, and the attractant is suitable for general popularization.
And (3) interfering mating: in the adult period, a sex pheromone attractant composition dispenser is generally arranged in the damaged arborvitae forest, the smell of sex pheromone exists everywhere in the air, so that males lose the directional ability on females, and females cannot be found for mating, or the antennae of the males are in a paralytic state due to long-time contact with the sex pheromone, and the reflective ability on the calling of the females is lost. The female insects cannot mate, and the offspring cannot be bred for harm.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.
