Description
Technical Field
The invention belongs to the technical field of agricultural pest control, and particularly relates to a method for controlling thrips pests by using pheromone and predatory natural enemies in a combined manner.
Background
Thrips is a general term for insects of the order Thysanoptera (Thysanoptera), which are tiny and often hidden in flowers and young leaves. Currently, 7700 and 570 species of thrips are recorded worldwide, and china accounts for more than 570 species [ major et al, 2011; mount et al, 2014 ]. Up to now, the species of thrips recorded all over the world are more than 2000, belonging to about 276 in the 4 subfamily, and 315 in the 79 genus in china [ huqingling, 2013 ]. Thrips have strong reproductive capacity, serious generation overlap and high outbreak frequency, the diffusion and harm of thrips pests are accelerated by global trade and climate warming, the thrips pests become one of the most main agricultural pest groups in the world gradually, and can spread various viruses including the spotted love virus and also are important external invasive pests for outbreak of disasters. Thrips feeding complexity including phytophagy, predation and bacteriophagy, wherein phytophagy thrips include harmful thrips that harm crops and beneficial thrips that control weeds; part of the thrips taeda is an important natural enemy of some small insects.
The plant volatile substances have effects of repelling and attracting insects, and killing some insects [ Dyeqing et al, 2010)]And has a synergistic effect with insect pheromones [ Selengchun et al, 2013]. Linalool oxide in Verbena plant has effect in attracting Frankliniella occidentalis, reducing toxic probability of thrips, and reducing harm [ Matsuuraet al.,2006]. Honeysuckle flower (1)Lonicera japonicaThunb) volatile substance cis-jasmoneThrips obscuratus(Crawford) has a remarkable attracting effect, but has a poor attracting effect on thrips tabaci [ El-Sayedet al., 2009]. Volatile substance methyl anthranilate for thrips palmi karny and thrips chromocor: (A)Thrips coloratusSchmutz), Frankliniella occidentalis (Thrips flavusSchrank) and Cirsium setosum both have good attractant effect [ Imai et al, 2001]. Eugenol, a plant secondary metabolite, slows down thrips activity and shortens spawning time, thereby reducing spawning amount and harm to crops [ Riefler et al, 2009]. The insect source information compound is used as a type of pheromone and plays an important role in regulating and controlling the behaviors of insects such as mating, gathering and the like. The insect population transmits information through the information compound to maintain the stability of the population. Insect pheromone as a non-chemical control measure can be used for monitoring the pest population dynamics and can be combined with other control measures to improve the pest control effect, and the insect pheromone control technology is also widely applied to the comprehensive control of pests. In recent years, the natural enemy also obtains one in the aspect of controlling thripsIn some progresses, under the current situation of outbreak and frequent occurrence of pests, one control measure is often difficult to solve all the problems, and particularly under the background that food safety and environmental protection are highly valued, the development of novel biological control is urgently needed.
The invention combines biological control and luring technology, and performs ecological control on the thrips in a mode of synergistic action of the thrips gathering pheromone, the natural enemies and the green leaf odor of plants, thereby playing a good control effect. Moreover, no report on the combined control of thrips by gathering pheromones and predatory natural enemies of thrips is found at present.
Disclosure of Invention
The invention aims to provide a method for jointly preventing and treating thrips pests by utilizing pheromone and predatory natural enemy, which is a method for jointly preventing and treating thrips pests by utilizing thrips gathering pheromone, plant green leaf odor and predatory natural enemy, and is realized by adopting the following technical scheme:
a method for preventing and controlling thrips pests by using pheromone and predatory natural enemies in a combined way comprises the following implementation steps: releasing the predatory natural enemies of the thrips into the thrips population, and simultaneously suspending the slow release carrier carrying the thrips pest pheromone compound on the thrips population by 0.01-0.5 m; so that the predatory natural enemies can prey on the thrips pests in the gathering process.
The predatory natural enemy is any one of orius pollicis guenee, Amara thistle, lacewing fly, trichogramma, and predatory mite.
The pheromone compound comprises the following components in percentage by mass: (R) -lavandulyl: neryl (S) -2-methylbutanate: cis-3-hexeneacetate = 1-3: 2-50: 0.1 to 0.5.
The preparation method of the slow release carrier carrying the thrips insect pheromone compound comprises the following steps: weighing (R) -lavandulyl, neryl (S) -2-methylbutanoate and cis-3-hexeneacetic ester according to the proportion, dissolving in normal hexane to prepare a slow release carrier solution with a certain concentration, adding 0.5mg of antioxidant 2, 6-di-tert-butyl-p-cresol and ultraviolet light adsorbent 2-hydroxy-4-methoxybenzophenone respectively, sealing in a polyvinyl chloride bag, and storing the slow release carrier in a refrigerator at 0-4 ℃.
It is another object of the present invention to provide the use of said method for improving the control of thrips pests by predatory natural enemies in vegetables or flowers. The invention combines the thrips agglutinin and the green leaf odor in an optimal proportion to form a slow release carrier which improves the effect of predatory natural enemies in preventing and controlling thrips pests; the slow release carrier and the predatory natural enemies are released simultaneously in the thrips high-incidence season in the flower or vegetable fields so as to achieve the purposes of controlling thrips, protecting the natural enemies and maintaining the biodiversity.
The invention discloses a method for jointly preventing and treating thrips pests by utilizing pheromone and predatory natural enemy, which takes thrips aggregated pheromone as a main component and plant green leaf smell as a synergistic component to prepare a slow-release carrier through different proportions, the probability of finding and eating the thrips by the predatory natural enemy is improved in the process of attracting the thrips to aggregate, the added cis-3-hexeneacetic acid ester can properly enhance the attraction rate of the thrips aggregated pheromone, and the stability and the lasting period of the released pheromone have better effect, thereby achieving the purpose of trapping and killing the pests. The prevention and control experiment proves that under the condition of using the invention, the prevention and control effect can be improved by 28-45% compared with the prevention and control effect of the predatory natural enemy or the pheromone which is independently applied, the technology of the invention has good effects on reducing the damage rate of vegetables or flowers, improving the quality of export flowers in China and protecting biodiversity and natural enemy resources, develops a new means of the pheromone in the field of preventing and controlling pests, and opens up an important way for a comprehensive prevention and control technical system of the thrips pests.
