| Biological control programs have been mounted in some region(s) of the world against 13 of the 16 dossier pests and substantial or partial success has been achieved in one or more countries for 8. On the basis of available information there are good to excellent prospects for reducing, in at least some parts of the region, the damage caused by the following: Leucinodes orbonalis , Nezara viridula , Ophiomyia phaseoli and Planococcus citri . There are also good reasons for believing that there will prove to be valuable natural enemies for the following: Agrius convolvuli, Anomis flava , Aphis craccivora , Aphis gossypii , Diaphorina citri , Dysmicoccus brevipes , Hypothenemus hampei , Phyllocnistis citrella and Trichoplusia ni . There seems to be little... |

| Larvae of the butterfly Erionota thrax, the banana skipper, destroy the leaves of bananas by eating them and forming massive protective rolls of leaf tissue. They were first observed in north-western Papua New Guinea in 1983 and over the next 6 years spread throughout the mainland at the rate of up to 500 km/year. E. thrax has also spread across the ocean to the east, to invade New Britain, Duke of York and New Ireland islands, and possibly Bougainville. As the banana skipper spread, it destroyed an average of some 60% of banana leaves, leading to both a serious delay in fruit maturation and reduced weight of banana bunches. Previous successful biological control of E. thrax when it invaded Mauritius, Hawaii, Guam and Saipan encouraged Papua New Guinea... |
