摘要

本研究於室內溫度25℃ ± 1℃，75% ± 10% RH，光照14 h：10 h（L：D）條件下，評估東方果實蠅（Bactrocera dorsalis Hendel）與瓜實蠅（Bactrocera cucurbitae Coquillett）卵作為錨紋瓢蟲[Lemnia biplagiata（Swartz）]代用食物的合適性，並以棉蚜（Aphis gossypii Glover）為對照食物。結果顯示，取食東方果實蠅及瓜實蠅卵之幼蟲發育時間、初羽化成蟲體重的表現不如取食棉蚜者，但供試之40隻幼蟲能完成發育為成蟲的數量與取食棉蚜者相近，分別為35、34 與36隻。錨紋瓢蟲成蟲取食此二種蠅卵的每雌一生總產卵量分別有512.2、405.2粒。因此，可認為此二種蠅卵為錨紋瓢蟲適合的食物。由於日齡－齡期別生殖力（fx，每雌產卵量）≥ 日齡別生殖力（mx，每成蟲產卵量），若雄性族群未被納入考量，可能會高估族群的增殖力。

The suitability of Bactrocera dorsalis Hendel and Bactrocera cucurbitae Coquillett eggs served as alternative food of the lady beetle [Lemnia biplagiata (Swartz)] was evaluated. Experiments were carried out under laboratory conditions at 25℃ ± 1℃, 75% ± 10% RH, and a photoperiod of 14 h:10 h (L:D). Results showed that the developmental period and adult body weight for the larvae raised on both flies eggs are inferior to that raised on the reference diet, Aphis gossypii Glover, with 35, 34 and 36 individuals completed into adulthood, respectively. Total number of eggs laid per female were 512.2 and 405.2 eggs when the adult were reared on eggs of both two fly species, respectively. Thus, eggs of both flies can be considered as the ”adequate” food for rearing L. biplagiata. Since the age-stage specific fecundity (fx, number of egg produced per female) was almost larger than the age specific fecundity (mx, number of egg produced per individual) obtained in this study, the increase potential of a population may possibly be overestimated if male population is not taken into consideration.
