Abstract
Abstract Although stilbene fluorecent brighteners have been demonstrated to increase the susceptibilities of many lepidopterous insects to insect viruses, little information exists on the effects of a brightener on the susceptibility of the codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae) and the false codling moth, Cryptophlebia leucotreta Meyrick (Lepidoptera: Tortricidae). In the present study, we tested the effects of the fluorescent brightener 28 (UNPA-GX) on increasing of the insects' susceptibility to a granuloviruses. The bioassay tests showed that brightener did not increase the susceptibility of codling moth neonate larvae and false codling moth larvae to the granulovirus (CpGV). The same result was obtained when the false codling moth GV was tested in presence of brightener against its homologous host. In addition, brightener failed to change the susceptibility of the codling moth to ClGV. In histological sections from the codling moth's midgut, the peritrophic membrane (PM) was fo...
期刊介绍:
The Journal of Agricultural and Urban Entomology (JAUE) (Journal of Agricultural Entomology, Jan 1984 - Oct 1998 volumes 1-15) is published under the auspices of the South Carolina Entomological Society (SCES). The Journal publishes contributions of original research concerning insects and other arthropods of agricultural and urban importance to include those affecting humans, livestock, poultry, and wildlife. JAUE is particularly dedicated to the publication of articles and notes pertaining to applied entomology, although it will accept suitable contributions of a fundamental nature related to agricultural and urban entomology.
