“…Earlier studies (Rukazambuga, 1996;Abera, 1997;Masanza, 2003) have shown that banana crop residues are favoured substrates for ovipositing females. The observations of this study suggest that success of immatures and fitness of emerging females are fairly similar on growing plants and residues of susceptible highland banana.…”

“…Oviposition is in the base of the plant. In highland banana, Abera et al (1999) reported highest levels of oviposition on flowered plants and residues, although, in plantain, Mesquita et al (1984) observed that tissue from younger plants was more suitable for larval development.…”

Abstract. Laboratory trials were conducted in Uganda at the Kawanda Agricultural Research Institute to determine attraction, eclosion success and larval survivorship of the banana weevil Cosmopolites sordidus (Germar) on crop residues of different ages. In the first experiment, studies focused on different types and ages of residues of one susceptible highland banana clone 'Nabusa' (genome group AAA-EA). Corms attracted 65% of the test weevils, pseudostems 30%, while 5% were non-respondents. Oviposition levels and the number of eggs per female were higher on young than old corms. Eclosion rates of , 1-day-old eggs inserted into corm pieces of residues (cultivar 'Kisansa', genome group AAA-EA) declined from 66% in residues collected , 2 days after harvest (DAH) to 58% in residues collected . 30 DAH. To assess immature survival, , 1-day-old 1st instar larvae were put on banana corms of suckers and crop residues of the cultivar Kisansa in single rearing chambers. The number of surviving individuals was recorded at 3-day intervals until adults emerged. Survivorship was 12% on sword suckers, 10% on maiden suckers and 7% on flowered plants; and 12% on residues collected , 2 DAH and 5% on residues collected . 30 DAH. Larval duration and mean days taken for adult emergence increased with plant and crop residue age. Females emerging from the different plant and residues treatments were similar in weight. The data suggest that all aged residues are suitable hosts for C. sordidus, suggesting that sanitation practices should be implemented soon after harvest.

“…Classical resistance mechanisms (Painter, 1951) have been investigated in Musa germplasm, and antibiosis (factors affecting larval performance), rather than antixenosis (attraction), appears to be the most important resistance mechanism in banana (Mesquita et al, 1984;Ortiz et al, 1995;Abera et al, 1999;Kiggundu, 2000;Gold et al, 2001). 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.
