Description
Technical field
The present invention relates to the wild snout moth's larva insect sex pheromone of beans major ingredient (E10, E12)-hexadecadienoic aldehyde with and the chemical synthesis process of analogue and intermediate.
Background technology
The wild snout moth's larva Maruca of beans testulalis Geyer is the important pests of present legume crop, bores moth property cause harm leaf, flower and beanpod.Because the leguminous crop harvest time is short, adopt the wild snout moth's larva of chemical pesticide control bean-pod borer and beans, residual quantity is big, can pollute beanpod.This worm eats into larva gets food in the beanpod, more hidden, agricultural chemicals is difficult for tagging, and simultaneously, mature larva is to take off to pupate after pod buries, and certain protection is also arranged, and therefore, difficulty of prevention and cure is very big.In the high-incidence season, the peasant adopts methods such as improving spraying medicine concentration, increase access times, use riskiest pesticide to prevent and treat usually, the result had had both killed and wounded natural enemy in a large number, destroyed the eubiosis in vegetable garden, cause insect rampant again, cause pesticide residue severe overweight in the vegetables again, influenced ediblely, bring out the resistance of vegetables pest simultaneously various conventional chemical agricultural chemicals.Legume crop is plucked in batches, and the collecting period is separated by closely, will pluck once in 2-3 days receipts phases of Sheng, after a lot of peasant households have executed agricultural chemicals, does not reach the just listing of fate of personal distance.
The unreasonable use agriculture chemical of vegetable grower, the abuse height poisons the medicine of learning to farm, severe contamination farmland, commodity vegetables and context, cause the content severe overweight of the pesticide residue in the vegetable products, have a strong impact on the healthy of people, bring difficulty for Vegetables Exportation, especially states such as Japan, European Union have strengthened the agricultural residual standard to agricultural products in China.This a series of problem has proposed new requirement and challenge to our pest control.Therefore, exploitation is new, effectively prediction and the method for preventing and treating seem very urgent.
More common in the world pest control technology comprises natural enemy, microorganism and semiochemicals technology at present.The semiochemicals technology has then that selectivity is strong, low risk and compatibility, causes the attention of various countries just day by day and applies.
Evaluation, the applied research work of the pheromone compound of the wild snout moth's larva of beans start from the nineties, all so far research work very limited (Adati, T.﹠amp; Tatsuki, 1999; Downham etc., 2003).Domestic only have observed to some biological habits and description (seeing following reference).The major ingredient that we have identified the wild snout moth's larva insect sex pheromones of China's beans for (E10, E12)-hexadecadienoic aldehyde.
