中文摘要 | 小癭蚊(Feltiella minuta (Felt))產卵於茄子葉背纖毛上,幼蟲捕食葉�臐A老 熟後做繭化蛹葉脈邊上, 常在葉脈交會處。 卵 0.22 mm 長, 老熟幼蟲 1.42 mm 長, 蛹 1.08 mm 長,繭 1.50 mm 長。在 15、20、25、28 及 30 ℃及 13:11 (L:D) 小時光暗週期 之定溫箱中,以神澤氏葉�� (Tetranychus kanzawai Kishida) 之卵為食,雌蟲自卵發育至 成蟲平均需 32.9、15.1、10.1、9.0、9.5 日, 雄蟲之發育期分別需 32.8、15.3、10.3、 9.0、9.2 日。其發育極整齊,同一日所產卵幾乎在同一日羽化為成蟲。 低溫時,卵及蛹期 在發育期中所占比例略高。 成蟲壽命甚短,各溫度下平均皆未及 5 日。飼以蜂蜜水,雌蟲 產卵量分別為 7.8、17.2、13.2、16.3、11.2 粒。 幼蟲可捕食各齡期的葉�臐A食量隨發育 生長而急速上升。雌性幼蟲可別捕食神澤氏葉�藃Z 195.3、187.5、167.6、165.0 及 142.5 粒,雄性幼蟲則捕食 173.3、153.5、132.0、140.7、122.1 粒葉�藃Z。 每日捕食量隨溫度 上升而增加, 以 28 ℃為例, 其捕食量介於黃角小黑隱翅蟲 (Oligota flavicornis (Boisduval & Lacordaire)) 與溫氏捕植�� (Amblyseius womersleyi Schicha) 之間。 連 續 4 年調查不施藥茄園, 本蟲均隨葉�藈皒s發生, 與黃角小黑隱翅蟲、 印度食�蟥狐� (Scolothrips indicus Priesner)、捕植�藀@同抑制葉�藈皒s。 發展 IPM 系統中應將癭蚊 的保育及利用列入考慮。 |
英文摘要 | Feltiella minuta (Felt) oviposits on hairs on the back of eggplant leaf . The larva feeds on spider mites, and pupates in a loosely spun cocoon, usually along the leafvein, often at the intersection of 2 veins. The lengths of egg, mature larva, papa, and cocoon averaged 0.22 mm, 1.42 mm, 1.08 mm, and 1.50 mm, respectively. Reared in an incubator at 15, 20, 25, 28 and 30 ℃, with a photoperiod of 13: 11 (L: D), and fed with eggs of Tetranychus kanzawai Kishida, the developmental period, from egg to adult, averaged 32.9, 15.1, 10.1, 9.0, 9.5d for female flies, and 32.8, 15.3, 10.3, 9.0, 9.2 d for male flies, respectively. This midge developed uniformly. Eggs deposited on the same day emerged to adult almost on the same date. The egg and pupal stages occupied a larger proportion of the whole developmental period at lower temperatures. The adult life span was short, usually less than 5 d. Fed with diluted honey, an adult female laid 7.8, 17.2, 13.2, 16.3 and 11.2 eggs at the respective temperatures. Larvae could beed on any stage of the spider mite. The feeding amount increased sharply as age increased. Each female larva consumed 195.3, 187.5, 167.6, 165.0, and 142.5 spider mite eggs, while each male larva consumed 173.7, 153.6, 132.0, 140.7, and 122.1 spider mite eggs, at the respective temperatures. Daily consumption increased as temperature increased. At 28 ℃, its feeding amount was less than that of Oligota flavicornis Boisduval & Larcodaire, but greater than that of Amblyseius womersleyi Schicha. Weedkly surveys made consecutively for 4 yr in eggplant fields which received no acaricide or insecticide application showed this midges always occurred and fluctuated after the spider mite population. It regulated the spider mite population together with O. flavicornis, Scolothrips indicus Priesner, and A. womersleyi. The conservation of this midge should be included in the IPM system. |
