With Sirex noctilio collected from infected areas in Heilongjiang and Inner Mongolia, the anatomical locations of the venom gland and venom reservoir were observed by dissecting the abdomen of female adult S. noctilio and their structural characteristics were observed under a microscope. The temperature was set at 50°C and the venom composition was analyzed at 5°C/min to 200°C with Thermo Scientific GC-MS. The venom gland and venom reservoir were located at the base of S. noctilio ovipositor. The venom reservoir was translucent crystalline tissue with the size of green beans, and its structural features is beneficial for S. noctilio to store as many venoms as possible. Venoms, among which fatty acids account for the major proportion, contain alkaloids, sugars and glycosides, fatty acids and proteins. The fatty acids include palmitic acid, palmitoleic acid, stearic acid and stearic acid, and the proteins in the venom component may be the active substances that cause damage to the host trees. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Application In Synthesis of Isopropylisothiocyanate).
Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Application In Synthesis of Isopropylisothiocyanate
