Description
Affiliated technical field:
The invention discloses a kind of red plam weevil aggregation pheromone microcapsules attractant, be used to lure red plam weevil, belong to the control of insect technical field.
Background technology:
The insect red plam weevil that the present invention relates to (Rhychophorus ferrugineus/Fabricius) is that coconut palm is destroyed insect; It also is the importance insect of other multiple babassus; Mainly causing harm with larva moth food trunk and tree crown lobus cardiacus, all is to invade through the injury or the crack of trunk usually, can also invade the tree body from the root that is positioned at the face of land; The plant surface that is injured looks excellent; All be destroyed but set the bar interior tissue in fact, in 5-6 month, just can cause cocoanut tree dead usually, the main host plants seeds have betel nut, oil palm, beautiful pin certain herbaceous plants with big flowers, triangle coconut, nipa palm, bottle coconut etc.According to J.R.Faleiro, the country of 15% cocoanut tree growth and the country of almost 50% palm plant growth all find the harm of this worm, serious threat regional ecotope and the babassu germ plasm resource of global tropical.Domesticly on the sharp date palm tree of being introduced in Guangxi and Guizhou in succession in 2002,2003 of Ghana, find the red plam weevil insect pest; In recent years in Shanghai of China, southern area rapid spread such as Guangdong, Fujian, Zhejiang; This worm is that the State Administration of Forestry newly issues one of 20 kinds of forestry quarantine harmful organisms (containing Quadrastichus erythrinae Kim) of enforcement; Its difficulty of prevention and cure is big, mainly shows following 3 aspects: the one, and the right natural disposition scope of this worm is very wide, and accommodative ability of environment is very strong; The 2nd, causing harm in early days is difficult for coming to light, when be prone to finding in the later stage to the degree that can't save; The 3rd, adult is hidden daytime; Nocturnalism; Be difficult for to catch and the spray medicine is tagged, larva bore moth and get food host plant interior tissue and the coconut palm height big, injection and spray medicine are difficult to prevent and treat larva; If adopt high malicious persistent pesticide then the destructible ecosystem, contaminated environment, do not meet the sustainable development requirement.Therefore; Mainly taking at present early prevention is main method for integrated control, uses guard in the trees seedling phase, can prevent the harm of red plam weevil; It is completely cut off with the tree that is injured makes it avoid infringement; And the trees more serious to early stage harm, dissectible carries out after chemical agent handles, again with on the intensive guard in case the adult that possibly survive escape.
At present; Confirming that Study on Technology has been seen multinomial report aspect the early stage harm trees both at home and abroad, according to Wei Juan etc.: utilize acoustic sounding, stethoscope and infrared system in the tree bar, to get the sound that food sends and confirm to monitor early stage harm when the red plam weevil population fluctuation is explored in the existence of larva through larva; And J Nakash uses cyberdog can find the harm tree rapidly in Ireland, monitors its early stage harm 100% success; Soroker utilizes stethoscope to get in the tree bar through larva and eats the existence that the sound that sends is confirmed larva; Utilize acoustic detection device (Larva Lausher, NIR, Bad Vilbel, Germany) and use application software analytic record data-signal can discern the different length of times and weight larva; Benedikt von Laar uses the CSC sensor that has different probe, and different worm attitude red plam weevils are divided into 5 kinds of different audio, combines other the method for preventing and treating can reach the control efficiency more than 90% in the field simultaneously.But these methods of preventing and treating need human and material resources, the financial resources of labor, are not suitable for large tracts of land and promote the use of.The chemical agent control is considered to prevent comparatively effectively means of red plam weevil diffusion and control harm; W Kaakeh has done toxicity test with the Imidacloprid dilution to the different worm attitudes of red plam weevil in 2006, and field test results shows that the lethality of larva and adult reaches 61.9% and 42.6% respectively; Report Rogor such as K M Azam and S A Razvi and water are better by 1: 2 dilution proportion liquid spray effect; Spray 0.2% gusathion m or 0.3% basudin and 0.15% of tree bar poisoned the slave girl with poison 2 times every month, and the stem stalk is injected 10% dichlorvos 100mL and used 5-10mL Imidacloprid soil deep irrigation (3 times every month), and certain effect is all arranged.But the chemical control destructible ecosystem and contaminated environment; The Biocidal technology of employing based on nematode, fungi, virus, bacterium etc. also arranged in recent years; But having the bio-safety problem equally, is a kind of more satisfactory method of effectively preventing and treating and utilize red plam weevil aggregation pheromone trapping red plam weevil.
Hallet in 1993 etc. separate from red plam weevil male worm body and obtain a kind of aggregation pheromone, and its principal component is 4-methyl-nonyl alcohol and 4-methyl-5 nonanone.United Arab Emirates 1996-1998 adopts the chemical spray control of combining information element trapping to compare independent spraying harm tree minimizing 30%.Reports such as Abraham in 1999 are a kind of effective methods with the food trapping red plam weevil of admixing aggregation pheromone.People such as Qin Wei power report in 2004 through the lure observation of several kinds of decoys to red plam weevil, finds that the attractant effect of aggregation pheromone significantly is better than other several kinds of decoys (live female worm, sugarcane, pineapple, Archontophoenix alexandrae Wendl et Orude).At present external synthetic aggregation pheromone has got into regular commercialization, can directly apply to the field trapping, also can directly be used for a certain regional red plam weevil adult insect density fluctuation monitoring, but it costs an arm and a leg.According to 2008 Mount Huang spring etc., China did not also have red plam weevil aggregation pheromone synthetic production technology, and the aggregation pheromone that field trial is used is to foreign procurement, and application cost is than higher.Though in recent years, China has obtained related developments in the aggregation pheromone prevention and control field research of red plam weevil, does not retrieve relevant red plam weevil aggregation pheromone microcapsules attractant preparation method's patent or relevant report so far.
Insect have very strong selection unicity to information; And a kind of pheromones is generally by multiple compound polymerization generation effect; The effect that different proportion component and burst size produce is different, and for example certain proportion component and burst size can produce and assemble signal efficiently, and ratio or concentration change a little to become and resists the gathering signal; Therefore, the ratio of each component and rate of release are the deciding factors of its attractive activity in the attractant.Simultaneously, difference lures the selection meeting of formulation directly to influence the persistence of attractant drug effect.
