The edible caterpillar Aegocera rectilinea Boisduval 1836, locally called Mikombidila, is collected from its wild habitat for consumption by people in the western region of the Democratic Republic of Congo (DRC). Its production by farming would represent a valuable source of animal protein for local populations. Working toward this end, the present study examined the life cycle of A. rectilinea, fed on Boerhavia diffusa L. leaves in an uncontrolled breeding room (26±2 °C, 77±6% relative humidity), starting with caterpillars previously harvested in Kinshasa, DRC. The fecundity of the females was 340.8 eggs on average, with an egg viability of 89.7%. Developmental phase durations of 19.8±1.6 and 12.5±1.9 days were observed for the larval and pupal stages, respectively. The mean total life-cycle duration, from egg to adult emergence, was 36.2±2.3 days, with a proportion of female of 0.785%. Adult longevity was 8.2±0.8 days for males and 8.0±2.0 days for females. The results of this study validate the interest for A. rectilinea rearing program to reduce food insecurity and protein deficiencies, particularly in western areas of the DRC.

AbstractBiotic factors (including insect pests) constrain field-grown tomato production in Senegal. However, little information is available on the identity and life system of key pests. The objectives of this study were to: (i) update key pest records of field-grown tomato in the central vegetable-producing area along the northern coast of Senegal, known as the Niayes area; (ii) map their spatial and temporal incidence and (iii) understand insecticide use by growers to control the pests. A total of 98 tomato fields distributed in three zones along a north–south transect in the Niayes area were monitored over four crop cycles from 2012 to 2014. As expected, the tomato fruitworm Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) was the most destructive pest with an occurrence of 92% in sampled fields (90/98) and up to 38% damaged fruits in one field at the time of sampling. The proportion of damaged fruits did not differ among zones, but was significantly higher in the early dry season compared to the late dry season. The invasive tomato leafminer Tuta absoluta Meyrick (Lepidoptera: Gelechiidae) was detected in 53% of sampled fields (52/98), mainly in the south of the Niayes area in the late dry season. Because of their ability to adapt to unstable environment and insecticides, this insect pest assemblage is a new challenge that farmers have to deal with while decreasing their use of broad-spectrum insecticides.
