证实了棕翅绿虫共生体 Plautia stali 的存在。后中肠表面的胃盲肠上皮细胞胞质中常见长杆状微生物。盲肠各腔均通过细孔通向中肠腔。在宿主细胞退化后，在菌细胞中增殖的共生体被释放到盲肠腔中。此后，共生体通过细孔被挤出到中肠腔中。有可能是成年雌性在产卵期间将共生体涂抹在卵表面，孵化出的幼虫可能会摄入共生体。菌体可能产生维生素 Al 或胡萝卜素和维生素 E，因为这些物质仅在盲肠中检测到。消毒剂抑制了共生体的垂直传播，从灭菌卵孵化的幼虫由于各种微生物（例如真菌、沙雷氏菌和/或葡萄球菌样细菌）引起的机会性感染而死亡，因此无法成为成虫。在卵表面施用锯齿状细菌会导致二龄幼虫的高死亡率。
The presence of a symbiont of the brown-winged green bug, Plautia stali was confirmed. Long bacilliform microorganisms were commonly observed in the cytoplasm of epithelial cells of gastric caeca on the surface of the posterior midgut.Each cavity of the caeca opened into the midgut cavity via a fine pore. Symbionts that had multipled in the mycetocytes were released in the cavity of the caecum following degeneration of the host cells. Thereafter, the symbionts were extruded into the midgut cavity through the fine pore. It is possible that the symbionts are smeared on egg surfaces by adult females during the oviposition, and the hatched lanae may ingest the symbionts. The mycetomes may produce vitamin Al or carotin and vitamin E, because these substances were only detected in the caeca. Vertical transmission of the symbiont was inhibited by disinfectant, and larvae hatched from sterilized eggs did not become adults due to death from opportunistic infections caused by various microorganisms such as fungus, Serratia and/or a Staphylococcus-like bacteria. Application of Serratin-like bacteria an the egg surface caused high mortality of 2nd inster larvae.
