“…Synthetic pheromone blends for Chilo suppressalis, C. sacchariphagus, Chilo indicus, Chilo auricilius and C. zacconius have shown satisfactory attractiveness to male moths in the field (25). Sex pheromones for B. fusca, C. partellus, S. calamistis, S. cretica, S. nonagrioides and C. ignefusalis have been identified and are available commercially (195,225).…”

▪ Abstract Cereals (maize, sorghum, millet, rice) are extremely important crops grown in Africa for human consumption. Of the various insect pests attacking cereal crops in Africa, lepidopteran stem borers are by far the most injurious. All 21 economically important stem borers of cultivated grasses in Africa are indigenous except Chilo partellus, which invaded the continent from India, and C. sacchariphagus, which has recently been found in sugarcane in Mozambique. C. partellus is competitively displacing indigenous stem borers in East and southern Africa. A parasitoid, Cotesia flavipes, was introduced from Pakistan for biological control of C. partellus and caused a 32–55% decrease in stem borer densities. This article is an attempt to summarize the status of knowledge about economically important cereal stem borers in Africa with emphasis on their distribution, pest status and yield losses, diapause, natural enemies, cultural control, host plant resistance, and biological control. Special attention is given to Busseola fusca and C. partellus, the most important pests of maize and grain sorghum.

“…Two light traps and five pheromone-baited traps similar to those described by , and Youm and Beevor (1995), were used at ICRISAT Sahelian Centre (ISC) station. Light traps consisted of a 250 W mercury-vapour bulb mounted on top of a 3 x 3 x 3 m screen cage with a door on one side to access and collect trapped moths.…”

Abstract-Studies were conducted at the ICRISAT Sahelian Centre, Niger, to assess damage and yield loss by the millet stemborer, Coniesta ignefusalis (Lepidoptera: Pyralidae) on Pennisetum glaucum (L.) R. Brown. Although 78% of stems were infested, late attack by the millet stemborer on millet plants resulted in bored stems yielding more than unbored ones. Artificial infestations with 5 and 10 larvae per plant at 2 weeks after plant emergence (WAE) resulted in 50 to 70% plants with deadhearts and 24 to 100% avoidable yield loss. At 4 weeks after plant emergence, infestations with 5 larvae and 10 larvae per plant resulted in 7% increase in yield and 16% yield loss, respectively. Therefore, both the age of plant and density of borer population at the time of infestation can influence resulting stemborer damage and yield loss on pearl millet.

“…Moreover, Teixeira et al (2008) evaluated the capture of M. domestica with traps installed at 1.00 m of height from the ground, due to the flight height of these flies. However, other studies assessing the best height for insect traps found no effect of this factor (MELO, 2011;YOUM, 1995). The authors of these studies, regardless of the effect of trap height, presented several hypotheses for these results, such as insect flight height, physical barriers by leaves and stems, and the effect of height in the attraction method.…”

The insect Cochliomyia hominivorax (Diptera: Caliphoridae) causes primary cutaneous myiasis, and the use of traps is an alternative to monitor this fly in the field. Thus, the objective of this work was to develop a low-cost trap for collecting C. hominivorax in the field. Three experiments were conducted, with six replications, in the experimental field of the Brazilian Agricultural Research Corporation (Embrapa -Agropecuária Oeste), in Ponta Porã, State of Mato Grosso do Sul, Brazil. Traps were developed using two-liter polyethylene terephthalate (PET) bottles cut in half, with 30 grams of bovine liver and water covering 90 % of the liver mass placed in the bottom half, using the upper half as a cover funnel to keep the captured flies in the bottom half. The experiments consisted of evaluations of different opening diameter of the trap entrance (3, 4, 6 and 7 mm) with traps installed at 1.16 m from the ground (Experiment 1), heights of installation of the traps (0.00, 0.40, 0.80, 1.20, 1.60 and 2.00 m from the ground) (Experiment 2) and bottle colors (yellow, blue, white, green, red and transparent) (Experiment 3). The collected data were subjected to Tukey's test (p < 0.05). The ideal traps for collecting C. hominivorax in the field were those with opening diameter of 6 mm, height installation of 1.20 m from the ground, using transparent PET bottles.
