應用旋風分離法分離粉斑螟蛾[Cadra cautella (Walker)]卵粒與沾附鱗粉

Abstract

粉斑螟蛾［Cadra cautella（Walker）］卵粒常被應用作為生物天敵的代用食餌，但其卵粒上所沾附的鱗粉可能干擾到應用時操作，故研發分離蛾卵與鱗粉之技術有利於生物天敵應用推廣。傳統過篩法將卵粒與沾附鱗粉分離，但過篩後卵粒上殘留的鱗粉仍多，且器械本身體積龐大。 Almond moth [Cadra cautella (Walker)] eggs are a critical type of factitious prey for beneficial insect enemy species. However, the residual adhesive scales on the eggs create commercial inconveniences. In previous attempts to solve these problems, conventional sieving device could not completely detach the scales from the moth eggs, and increased equipment size.
