柑桔窄胸天牛（Philus antennatus）之形態與發生調查

Morphological and ecological studies of Philus antennatus

柑桔窄胸天牛(Philus antennatus (Gyllenhal))又稱褐色大眼天牛、橘狹胸天牛、狹胸桔天牛，屬鞘翅目（Coleoptera）、太古天牛科（Vesperidae）（又稱舊天牛科）之昆蟲，主要分布於台灣、中國大陸（福建、江西、廣東、海南、香港、廣西、福建、湖南、浙江、江蘇、陜西、河北）及印度等地。

"Philus antennatus (Gyllenhal) (Coleoptera: Vesperidae) is a notorious pest in the Matou wentan,Citrus grandis, Osbeck cv. Matou Wentan, and Matou peiyu orchards of Madou Township, Tainan County, southwestern Taiwan. The larvae of P. antennatus develop in soil, damage the roots of Matou wentan and Matou peiyu, and cause defoliation of the tree and eventual death. The morphology of each stage of P. antennatus is illustrated and described in this article. Surveyed in May, 2004, the emergence of adult of P. antennatus peaked at May 27, on which night we caught 1690 adults of P. antennatus. The fecundity was 509.3 ± 118.2 eggs/female."
