NORHISHAM AR、FAIZAH A 和 ZAIDON A. 2015。水分含量对竹螟 Dinoderus minutus 的影响。竹螟 Dinoderus minutus（鞘翅目：Bostrychidae）对砍伐的竹秆和产品的侵染是竹业中的一个严重问题。然而，对恐龙属物种的生物学研究很少。这项研究考察了竹螟的发育和繁殖方面。在 25 ± 3 °C、8 小时光照-16 小时黑暗条件下，观察了不同水分含量的 Gigantochloa scortechinii 下 D. minutus 的钻孔行为和生物学。 Dinoderus minutus 成虫在不同含水量下的钻孔能力和寿命存在显着差异。早在竹子砍伐时就发生侵染，当含水量降至15%时侵染变得严重。雌性甲虫将卵单独产入后生木质部，孵化期为 4 至 6 天。幼虫沿着后生木质部取食，留下紧密堆积的粪便。竹子中 D. minutus 的总生命周期为 98.28 ± 1.26 天。
NORHISHAM AR, FAIZAH A & ZAIDON A. 2015. Effects of moisture content on the bamboo borer Dinoderus minutus. Infestation by the bamboo borer Dinoderus minutus (Coleoptera: Bostrychidae) on felled bamboo culms and products is a serious problem in the bamboo industry. However, biological studies on Dinoderus species are scarce. This study examined the development and reproductive aspects of the bamboo borer. Boring behaviour and biology of D. minutus at different moisture contents of Gigantochloa scortechinii were observed at 25 ± 3 °C under 8 hours light–16 hours dark regime. Dinoderus minutus showed significant differences in boring capacity and lifespan of adult beetles at different moisture contents. Infestation occurred as early as felling of bamboo and became severe as moisture content decreased to 15%. Female beetles deposited eggs individually into the metaxylem and incubation period varied from 4 to 6 days. Larvae fed along the metaxylem, leaving behind tightly packed frass. The overall life cycle of D. minutus in bamboo was 98.28 ± 1.26 days.
