Oviposition of M. alternatus is not evoked by volatiles from dying or paraqaut-treated pines, but by nonvoltiles occuring in pine inner bark only in the presence of free moisture. Cabium and xylem are not necessary for this behavior.Behavior of cutting a pit in outer bark prior to ovipositor insertion was independent of moisture content of outer bark and the host plant-volatiles. This behavior is derived from nonvolatiles of outer bark.Behavior of ovipositor insertion appears to be induced by a wide variety of nonvolatiles in inner bark only in the presence of free moisture.The oviposition stimulants in pine inner bark are extractable in 70% acetone, methanol, water or dimethyl formamide. From bioassays and chemical analyses, the ovipositional stimulants appear to be phenolics having molecular weight of less than 1000 and carbohydrates which produce substances,in the presence of sulfuric acid and anthrone, that contribute absorption maximum between 583 to 583 nm.

松树松树的产卵不是由垂死的或经过百草枯处理的松树的挥发物引起的，而是由仅在存在游离水分的情况下松树内皮中出现的非挥发物引起的。硬皮层和木质部对于这种行为不是必需的。在产卵器插入之前在外树皮上切坑的行为与外树皮的水分含量和寄主植物挥发物无关。这种行为源自外树皮的非挥发性物质。产卵器插入的行为似乎是由内树皮中的多种非挥发性物质仅在存在游离水分的情况下诱导的。松树内皮中的产卵刺激剂可在 70% 丙酮、甲醇中提取、水或二甲基甲酰胺。从生物测定和化学分析来看，产卵刺激剂似乎是分子量小于1000的酚类物质和碳水化合物，它们在硫酸和蒽酮存在下产生物质，在583至583 nm之间产生最大吸收。
