| Abstract: | Larvae of the potato tubermoth (PTM), Phthorimaea operculella, feed on potato plants and tubers and are a major pest in the tropics and subtropics worldwide, causing up to 100% damage. The PTM granulovirus (PhopGV) provides significant potato protection, but little is known about its effect on larval development or its histopathology. Here we show that only 10% of larvae exited from PhopGV-treated tubers (1.4 × 108 granule/ml), lagging significantly behind controls, and most of these died by 72 h after emergence. Histopathology studies showed the fat body and epidermis were the principal tissues infected. PhopGV morphogenesis was similar to other GVs, the exception being small vesicles between mature granules. |
