“…At the same time, weevil attraction to corm pieces in laboratory choice experiments were not related to host-plant susceptibility (Kiggundu, 2000). Finally, Minost (1992), Pavis & Minost (1993), Musabyimana (1995), Abera (1997), Sumani (1997), and Abera et al (1999) found no relationship between host-plant attractivity and weevil damage levels under field conditions.…”

“…Budenberg et al (1993) identified banana kairomones as important in attracting banana weevils to their host plants. In field and laboratory studies, however, attraction to banana corms and pseudostems did not reflect host-plant susceptibility (Minost, 1992;Musabyimana, 1995;Abera, 1997;Sumani, 1997;Kiggundu, 2000). Moreover, Abera et al (1999) found oviposition rates on the resistant cultivar Kayinja to be similar to those on five highland banana cultivars.…”

A field screening trial undertaken in Uganda showed that a number of Musa L. (Musaceae) cultivars and hybrids displayed high levels of resistance to banana weevil, Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae), while most highland banana cultivars tended to be susceptible to weevil attack. In this study, research was undertaken to determine modalities of resistance to banana weevil. Laboratory studies suggested that all cultivars were attractive to the weevil and that females freely oviposited on all cultivars. While some differences were found between cultivars in attractivity and egg numbers, these were not related to subsequent damage. Therefore, antixenosis does not appear to play an important role in host-plant resistance to banana weevil. Larval survivorship rates in living corms were, for the most part, low on resistant cultivars, suggesting that antibiosis mechanisms offer the primary avenues of resistance. In the laboratory, development was slower on some resistant cultivars although survivorship rates on excised corm material were not as well related to levels of resistance as that on living material. Sap appeared to play a minor role in reducing egg eclosion rates on some resistant cultivars. Methanol extracts from Kayinja, a resistant cultivar, inhibited larval development on corms of susceptible cultivars in the laboratory.

“…Although some differences in attracting adult weevils to different cultivars have been identified no direct correlations between weevil resistance and plant damage were found (Buddenburg et al, 1993;Pavis and Minost, 1993;Abera et al, 1999;Kiggundu, 2000;Musabyimana et al, 2000). It was reported that differences in attraction have been due to environmental factors such as soil moisture around a cultivar with high sucker number (Ittyeipe, 1986).…”

Banana weevil is a serious pest of bananas and plantains in Africa. The development of resistant cultivars is seen as the long term and more sustainable control strategy. The difficulty in conventional breeding of bananas and plantains has prompted efforts towards the use of genetic transformation for banana and plantain improvement. In this review, the current status of banana weevil resistance, sources of resistance and resistance mechanisms is assessed. Further, current efforts and future prospects for identifying resistance genes outside the genus Musa with potential to control banana weevil in a transgenic approach are outlined and discussed.
