Embodiment Construction

[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0044] 1. Extraction of sex pheromones

[0045]Collect aged or mature larvae, raise them in the laboratory, and prepare them after eclosion; use sexually mature unmated female moths, aged 2-3 days after eclosion, and extract them 5-6 hours after dark at night. Take adult moths, after ether anesthesia, press the abdomen lightly with medical surgical tweezers, then cut off the 3 segments at the end of the abdomen, transfer them into a clean pointed-bottomed glass vial filled with about 100 μl double-distilled n-hexane, soak for 10 minutes, and draw Part of the solution was transferred to a sharp-bottomed glass tube, concentrated under slight nitrogen, and analyzed by gas phase-mass spectrometry.

[0046] 2. Identification

[0047] Gas phase analysis conditions: All synthetic sex pheromone compounds are analyzed on Agilent6890GC-5975MS, the chr...

Abstract

The present invention relates to a sex pheromone composition of orthaga olivacea warre, and a lure core thereof. The sex pheromone composition is characterized in that the sex pheromone composition comprises cis-11-hexadecenyl acetate, trace amounts of cis-11-hexadecenoic enolase and cis-11-hexadecenal. Antioxidants between 1% to 10% of the total component by mass and anti-ultraviolet stabilizers between 1% to 10% of the total component by mass are added into the prepared composition. A releaser can be prepared froma chlorobutyl rubber or a PVC capillary tube. The present invention firstly discovers and identifies that lures of the sex pheromone of orthaga olivacea warre are cis-11-hexadecenyl acetate, trace amounts of cis-11-hexadecenoic enolase and cis-11-hexadecenal, and concludes that each lure core has luring effects on male orthaga olivacea warreat at a dosage of 10 to 4000 micrograms, and the optimal dosage of each lure core is 1000 micrograms. According to the present invention, the sex pheromone composition of orthaga olivacea warre combined with a trapping device can effectively booby a large number of male orthaga olivacea warre, and can be applied to monitoring, prevention and controling of orthaga olivacea warre populations. The sex pheromone composition plays an important role in orthaga olivacea warre trapping and forecasting.

Description

technical field [0001] The invention relates to a sex pheromone composition of the camphor moth and related lures. Background technique [0002] Stericta (Orthaga) olivacea warre, also known as camphor borer and camphor borer, belongs to Lepidoptera (Lepidoptera) and Pyralidae. It is an important pest of garden plants. It is mainly distributed in In Jiangsu, Zhejiang, Shanghai, Fujian, Jiangxi, Hunan and other provinces (cities), it mainly harms Cinnamomum camphora (L.), Litsea cubeba, Lindera glauca and other Lauraceae plants. Camphor is an important timber and special economic tree species in the subtropical region (southwest region). Because of its dense branches and leaves, large crown and shade, majestic tree posture, it can smoke and block dust, conserve water sources, fix soil and sand, and beautify the environment. An excellent tree species for greening, it is widely used as shade trees, street trees, shelter forests and scenic forests. There are 23 cities in China ...
