ゴマダラカミキリの生態に関する研究 : II. カンキツ樹に接種した卵の孵化率ならびに若齢幼虫の生存率と樹脂滲出との関係  [in Japanese] Ecological Study of the White-Spotted Longicorn Beetle, Anoplophora malasiaca THOMSON (Coleoptera, Cerambycidae) : II. Hatchability of Eggs and Survival Rate of Young Instar Larvae in Relation to Gum-exudation in Artificial Inoculation Sites on a Citrus Tree  [in Japanese]

無防除のウンシュウミカン園でカンキツ樹の4部位に卵を人為的に接種し, 各部位における接種卵の孵化率, 孵化幼虫の初期生存率, 卵接種点からの樹脂の滲出について実験観察した.その結果, 卵の孵化率と若齢幼虫の生存率は樹脂滲出と密接な関係があり, 樹脂が卵および若齢幼虫の重要な死亡要因であることが明らかとなった.

Eggs of Anoplophora malasiaca THOMSON were artificially inoculated in four different sites on a citrus tree. Hatchability of the inoculated eggs, survival rates of young instar larvae and exudation of gum were observed in each inoculation site. Hatchability of eggs and mortality rate of larvae were closely related with the exudation of gum, and were lowered at the site where the gum-exudation rate was high.
