Abstract

<p>Three groups of adult Anoplophora malasiaca (Coleoptera: Cerambycidae) females fed on mandarin orange (MO), Japanese black pine (JBP), and Japanese white pine (JWP) branches for 2 weeks were compared for oocyte development and survival rates. Survival rates after 2 weeks of feeding on MO, JBP, and JWP branches were 100, 37, and 40%, respectively. In the two-choice tests (MO vs. JBP and MO vs. JWP), all females preferred MO, rather than JBP or JWP. MO-fed females developed several mature and immature oocytes in their ovaries after 1 and 2 weeks of feeding. However, none of the JBP- and JWP-fed females developed any oocytes. Thus, JBP and JWP are not suitable food plants for adult A. malasiaca females.</p>
