หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Feeding Preferences and Reproduction of the False Powder Post Beetle, Sinoxylon anale Lesne, on Two Clones of the Par? Rubber Tree) ผู้เขียน:Wisut Sittichaya, Aran Ngampongsai, Surakrai Permkam, บัวผัน พวงศิลป์ สื่อสิ่งพิมพ์:pdf AbstractThe feeding preference and reproduction of Sinoxylon anale on two rubberwood clones (PB235, RRIM600 and the main branch of clone RRIM600) were investigated. No-choice and multiple-choice feeding tests were designed to determine the feeding preference of the beetle, whereas laboratory reared beetles were used for reproductivity measurements. Adult S. anale preferred rubberwood clone PB235 over both types of wood from clone RRIM600. In a multiple choice test, 60% of the beetles chose rubberwood clone PB235, and of the remainder, 24% and 16% chose wood from the trunk and branch of clone RRIM 600, respectively. The adult beetles also showed a highly significant (P < 0.001) preference for feeding on wood from clone PB235 (0.295 ? 0.028 g) over trunk wood from clone RRIM 600 (0.253 ? 0.029 g) but there was no significant difference in the preference shown for wood from the RRIM600 branch (0.275 ? 0.021g). S. anale also produced the greatest number of progeny in clone PB235 (39.07 ? 17.30 individuals), significantly greater (P < 0.01) than the number produced in the trunk wood (25.73 ? 8.41 individuals) and the branch wood (22.47 ? 2.73 individuals) from the RRIM600 clones. The results indicated that S. anale seemed to prefer (as well as being more reproductive in) wood with a higher starch content. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Powderpost Beetle Communities (Coleoptera: Bostrichidae) in Durian-Based Agricultural Areas in Southern Thailand) ผู้เขียน:Wisut Sittichaya, Narit Thaochan, ดร.วัฒนชัย ตาเสน, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractThe xylophagous powder post beetles of the family Bostrichidae are serious insect pests of forests and forest products, but studies of their ecology are rare. The present study investigated the communities of bostrichid beetles associated with durian-based agricultural areas in two study zones from southern Thailand. In total, 17 bostrichid species were collected, 15 in mixed-crop and 14 in monocrop systems. Xylothrips flavipes (Illiger) was the most common species in both systems (56.8% of all beetles caught). Mono-crop durian orchards had significantly more beetles per trap than mixed-crop orchards, but the relative abundances of species were similar (percentage similarity, 86.7%). The seasonal flight pattern in the durian orchards was more or less bimodal. The first abundance peak occurred at the beginning of the rainy season (May– July) and the second peak during the final weeks of the rainy season (November –January). Bostrichid numbers were more significantly correlated with climatic variables measured during the previous two months than with the current values, suggesting an effect on beetle development. |
