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: 2253-73-8Computed Properties of C4H7NS).
Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Computed Properties of C4H7NS
