以豐年蝦卵為代用食餌繁殖南方小黑花椿象

Abstract

南方小黑花椿象［簡稱小黑椿，Oriusstrigicollis（Poppius）］（Hemiptera:Anthocoridae）是防治薊馬等小型害蟲有效的天敵，以往其繁殖是以粉斑螟蛾［Cadracautella（Walker）］卵為食餌。 The predatory bug, Orius strigicollis (Poppius), is usually mass-reared on eggs of the flour moth, Cadra cautella (Walker). The objective of this study was to determine if the rehydrated dry cysts of brine shrimp, Artemia franciscana, can be used as an alternative source of food to replace eggs of flour moth for mass rearing of O. strigicollis. The O. strigicollis were reared on 4 combination food, shrimp cysts for lifetime, moth eggs for lifetime, shrimp cysts for nymph and moth eggs for adult, moth eggs for nymph and shrimp cyst for adult, comparing influence on development and fecundity for successive generations.
