Abstract
The invention discloses an attractant for Anagrus nilaparvatae which are natural enemies of rice planthoppers, which comprises components including linalool, liquid paraffin, 2, 6-di-tert-butyl-p-cresol and 2-hydroxy-4-methoxybenzophenone in a weight ratio of (0.01-0.10):(0.2-2):(0.01-0.1):(0.01-0.1). The attractant can attract female adults of Anagrus nilaparvatae which are important natural enemies of rice planthoppers in ovigerm stage, so as to reduce the quantity of rice planthopper colonies and reduce the damage of the rice planthoppers to rice plants. The attractant has the characteristics of low cost, high efficiency, environmental friendliness, safety for human beings and livestock, and the like. The attractant for Anagrus nilaparvatae which are the natural enemies of the rice planthoppers have a bright industrialization prospect; and as the preparation method is simple, the attractant is particularly suitable to be used in pollution-free production of rice and can create great economic, social and ecological benefit.
Description
Technical field
The present invention relates to a kind of natural enemy attractant that can effectively control rice fulgorid adult quantity, particularly relate to a kind of natural enemy attractant that utilizes host plant volatile that insect pest induces that the population quantity of rice fulgorid is controlled.
Background technology
Rice fulgorid is one of most important insect on China staple food crop paddy rice, wherein with white-backed planthopper
Sogatella furciferaAnd brown planthopper
Nilaparvata lugens(St l) harm is the heaviest.As to its in addition in time control, break out and to cause very serious loss to China's rice yield when serious.The brown planthopper great outburst appears in most of paddy rice producing region on the south China the Changjiang river in 2005, brings massive losses for national Rice Production, gives a lesson to very deep.Present stage still mainly relies on chemical pesticide in China's Rice Production on to the control of rice fulgorid, natural enemy, contaminated environment yet long-term excessive use chemical pesticide not only kills off the insect pests also can cause the pesticide resistance of insect and the problem such as rampant again.Therefore, developing safely and effectively, biopesticide has become one of important directions of cash control rice fulgorid harm.
Plant can specific release volatile materials after being subject to plant-feed insect harm, and these herbivore-induced volatiles that discharge can be lured the natural enemy of plant-feed insect, thereby make plant reach the purpose of defence.In recent years, existing the experimental results shows that herbivore-induced volatile can lure the natural enemy of plant-feed insect, some researchs identify the main component of herbivore-induced volatile, and have found the crucial active component that the plant-feed insect natural enemy is played attracting action by the Collection and analysis of volatile matter.James etc. (2003) utilize first artificial synthetic herbivore-induced volatile component in the garden of plantation hop these components of investigation to the natural attracting action of useful insect.Found that the artificial synthetic herbivore-induced volatile component take MeSA and (Z)-3-hexenyl acetate as representative can significantly be lured the useful insect of multiple in the rural area or section.James(2005) again utilize the herbivore-induced volatile component to carry out field trapping experiment, find that the useful insect of total at least 13 kinds or section can be lured by one or more herbivore-induced volatile components.Wherein, MeSA can lure the multiple beneficial insect.Yu(2008) carry out epigamic experiment in the cotton field and find, MeSA and (Z)-herbivore-induced volatile components such as 3-hexenyl acetate can be lured multiple natural enemy insect.These field experiments result shows that herbivore-induced volatile has important value in the middle of control of insect, particularly in biological control.Because plant-derived self metabolism of herbivore-induced volatile, therefore having avoided to a certain extent now, chemical pesticide excessively uses all additional hazard that ecotope is brought.The herbivore-induced volatile component has very important potential value to the biological control of following insect.
For rice fulgorid, still do not have so far about strengthening attractant exploitation and the application of its Effectiveness of Natural Enemies.For this reason, special proposition content of the present invention thinks that improving rice fulgorid improvement provides effective method.
Summary of the invention

Test example 1
The rice planthopper natural enemy rice lice tassel chalcid fly attractant that adopts embodiment 12 to make.Use Y-shaped smell sensing apparatus to measure rice lice tassel chalcid fly to the behavior reaction of this attractant.Two arms of " Y " type olfactometer and straight tube be long 10.0cm all, internal diameter 1.0cm, 75 ° of two arm angles." Y " type two arms link to each other by silicone tube and 2 flavor source bottles (put the filter paper that contains attractant in the bottle, another puts the filter paper that contains contrast agents) respectively.After opening air pump, air-flow before entering flavor source bottle first through an active carbon filter and a distilled water bottle, to purify air and to increase air humidity.The air flow rate of each arm is controlled at 150ml/min by flowmeter.Whole living survey process is 28 ℃ indoor carrying out.Place a 25W incandescent lamp at 25cm place, the place ahead of olfactometer, with controlled light.
The attractant solution that before the experiment 10 μ l is prepared is added on (long 1.5cm, wide 0.5cm) on the quantitative filter paper sheet, puts into simply source bottle (long 10.0cm, internal diameter 1.0cm); In addition 10 μ l control solvent are added on the quantitative filter paper sheet, put into another flavor source bottle.Connect experimental instrument, connect air pump.Adopt little dactylethrae that rice lice tassel chalcid fly queen bee is introduced in the straight tube of Y-shaped smell sensing apparatus by head.Observe the behavior reaction of putting down in writing rice lice tassel chalcid fly in 10 minutes, put down in writing it to the selectivity of two arm odor sources.Selection criteria is: when it gets over the 7cm place of a certain side arm and continues 1min when above, remember that then this honeybee makes a choice to the odor source of this arm.If chalcid fly does not make one's options after introducing 10min yet, then is designated as reactionless.Be the phase mutual interference between the elimination natural enemy and the impact of some other factor, every giving birth to surveyed 2 honeybees just with 99% alcohol wash olfactometer, and dries in 100 ℃ of baking ovens, changes simultaneously olfactometer two arm directions when next secondary survey.Measure altogether 40 of rice lice tassel chalcid flies.To measured result, analyze attractant to the attracting action of rice lice tassel chalcid fly with statistical method.
Data from Fig. 1 can find out that rice planthopper natural enemy rice lice tassel chalcid fly selects the quantity of attractant obviously more than solvent control, and namely attractant has obvious attracting action to rice lice tassel chalcid fly.The rice planthopper natural enemy attractant that utilizes embodiment 7-11 to make carries out test same as described above, also can obtain similar experiment effect.
Test example 2
The rice planthopper natural enemy rice lice tassel chalcid fly of adopting embodiment 13 to make lures core.Get paddy field, be divided into 6 equal residential quarters, each residential quarter area is 9 ㎡ (the wide guard row of 1m that are of 3m * 3m) and outward enclose.3 are made as control group in 6 residential quarters, and 3 are made as processed group.In each residential quarter the location 4 clumps of paddy rice, between each clump paddy rice and and cell edge between all at a distance of 1m.With luring core to hang on the rice clump stem stalk of location, apart from ground 20cm, carry out mark.Each site of clip hangs and lures the rice clump of core after 7 days, records the sum of brown planthopper ovum on every clump of paddy rice and the ovum number of quilt parasitism and prey.Computing and control plot brown planthopper ovum by parasitic rate.
Can find out from the data of Fig. 2, making lure core can significantly improve field rice fulgorid ovum by parasitic rate, namely attractant has obvious attracting action to rice lice tassel chalcid fly.The rice lice tassel chalcid fly attractant making that makes with embodiment 7-11 lures core, and carries out test same as described above, also can reach similar technique effect.
