“…C. partellus, the dominant borer species, on the other hand, does however show strong preference for Napier grass to maize. Mohamed et al (2004), Khan et al (2006) and Van den Berg (2006a) found that C. partellus preferentially chose Napier grass varieties for oviposition over maize in two-choice tests. Subsequent larval survival to the adult stage on the majority of Napier grass varieties was below 10% compared to 60% on maize.…”

Napier grass, Pennisetum purpureum (Schumach), in combination with intercrops has been used successfully in habitat management for maize stem borers in Africa. The use of Napier grass only as a trap or barrier plant for Chilo partellus (Lepidoptera: Crambidae) and Busseola fusca (Fuller) (Lepidoptera: Noctuidae) was evaluated in this study. Napier grass borders were planted only on two sides of small-scale farmers' maize fields, since planting of perennial trap crops on all sides of fields hampered mechanical cultivation. C. partellus was the dominant borer species, followed by B. fusca and Sesamia calamistis (Hampson) (Lepidoptera: Noctuidae). Reductions between 0% and 27.4% in the incidence of borerinfested plants were observed on the 16 farms evaluated in this study. The results show that Napier grass as trap/barrier crop suppresses stem borer numbers in maize fields.

“…or Hyparrhenia rufa (Nees) Stapf. (Mohamed et al 2004;Se´tamou et al 2005). More stem borer species with higher number of individuals per plant on millet and sorghum than on maize might also be explained at least in part by differences in the distribution or extent of cereal crops cultivation in this ecological region, as these stem borer pests will be expected to thrive well only on host plants that are more abundantly and readily available.…”

Field data collected during the rainy season of two years, 2010 and 2011, were used to determine the per cent plant infestation and stem borer abundance on cultivated cereal crops grown by farmers' in Jere or the Sudan-Sahelian savanna ecological region of Nigeria. Stem borers were recovered using destructive sampling. Mean total per cent plant infestation and stem borer abundance per farmers' field were significantly higher on millet (40% and 25 individuals, respectively) and sorghum (30% and 21 individuals, respectively) than on maize (19% and 13 individuals, respectively). Of the five stem borer species found in this study, Coniesta ignefusalis (Lepidoptera: Pyralidae) (3.5)/Chilo sp. nr. aleniellus (Lepidoptera: Crambidae) (2), Busseola fusca (Lepidoptera: Noctuidae) (3.1)/ Sesamia calamistis (Lepidoptera: Noctuidae) (2.4) and S. calamistis (2.9), with significantly higher number of individuals per plant, tended to be more important pests on millet, sorghum and maize crops, respectively. Although, mean total per cent plant infestation and abundance of stem borers in this study were generally moderate, further studies on the effects of different types of cereals intercropping (locally practiced) on stem borer infestation and abundance should ascertain the true importance of these pest species in the Sudan-Sahelian savanna ecological region of Nigeria.

Bt‐maize as a potential trap crop for management of Eldana saccharina Walker (Lep., Pyralidae) in sugarcane

Notwithstanding the introduction of several pest management tactics, the stalk borer Eldana saccharina Walker (Lep., Pyralidae) remains the most serious pest in South African sugarcane. A novel tactic for managing this pest in sugarcane would be the use of a dead-end trap crop that attracts moths for oviposition and curtails subsequent larval development, thereby reducing pest population size. Glasshouse bioassays, in which moths chose to oviposit on maize producing Bacillus thuringiensis Cry1Ab toxin (Bt-maize), non-Bt-maize or sugarcane of two cultivars (borerresistant and -susceptible), showed that E. saccharina laid significantly more eggs and egg batches per dry leaf and unit mass of dry leaf on maize (Bt or non-Bt) than on either of the cane cultivars. When moths had a choice of ovipositing on 2-, 3-, 4-or 5-month-old maize (Bt and non-Bt), dry leaf number and mass of dry leaf material was significantly correlated with number of eggs and egg batches, indicating that older plants, which carried larger amounts of dry leaf matter, were more attractive for oviposition. Finally, glasshouse assays in which hatching larvae fed on 2.5-, 3.5-and 4.5-month-old Bt and non-Bt-maize plants, showed that the Cry1Ab toxin was effective in killing E. saccharina larvae in all Bt-maize plant growth stages, confirming that Bt-maize fulfilled the third requirement (curtailing larval development) of a dead-end trap crop for this pest. We argue that Bt-maize warrants further testing in the field as a trap crop, both alone and as a component of a Ôpush-pullÕ or habitat management system for E. saccharina in sugarcane.
