    Development of an optimum diet for mass rearing of the rice moth, Corcyra cephalonica (Lepidoptera: Pyralidae), and production of the parasitoid, Habrobracon hebetor (Hymenoptera: Braconidae), for the control of pearl millet head miner
    Amadou, Laouali; Baoua, Ibrahim; Ba, Malick N.; Muniappan, Rangaswamy (Muni) (Library of the University of Arizona, 2019-02-28)
    The rice moth, Corcyra cephalonica Stainton, an alternate host for the production of the parasitoid, Habrobracon hebetor Say, was reared on different diets, including pearl millet [Pennisetum glaucum (L.) R. Br.] (Poales: Poaceae) flour only, and in combinations of flours of sorghum [Sorghum bicolor (L.) Moench] (Poales: Poaceae), peanut (Arachis hypogea L.) (Fabales: Fabaceae), and cowpea [Vigna unguiculata (L.) Walp.] (Fabales: Fabaceae) to identify the optimal and economical proportion to be used under the conditions of Niger. The addition of cowpea or peanut to the pearl millet diet slightly increased C. cephalonica larval development time. Likewise, the addition of cowpea or peanut to cereal diets yielded a higher C. cephalonica larval survival. Female moths emerging from larvae fed on cereal and legume mixed diets produced higher eggs compared to the ones fed on sole and mixed cereals. Among legumes, cowpea addition is most interesting in terms of cost/production of C. cephalonica larvae. However, female moths emerging from larvae fed on different millet cowpea mix (5, 25, and 50%) laid significantly more eggs than those fed on sole pearl millet. Further, individual C. cephalonica larvae fed on 75% pearl millet + 25% cowpea produced significantly more H. hebetor. With an initial 25 C. cephalonica larvae kept for a 3-mo rearing period, the number of H. hebetor parasitoids produced will reach 2.68–10.07 million. In terms of cost/production ratio, the 75% pearl millet: 25% cowpea yielded better results. © The Author(s) 2019.

    A Guide to Biological Control of Fall Armyworm in Africa Using Egg Parasitoids
    Tefera, Tadele; Goftishu, Muluken; Ba, Malick N.; Muniappan, Rangaswamy (Muni) (Virginia Tech, 2019)
    The Integrated Pest Management Innovation Lab (IPM IL) has been addressing the Fall Armyworm (FAW) problem in Africa since May 2017, when it invaded Ethiopia. Even though FAW prefers maize, it is polyphagous and can infest over 300 species of plants. Several workshops supported by international organizations were held in different parts of Africa over the past three years; however, they mostly concentrated broadly on IPM approaches for FAW management on maize, with little or no emphasis given for management on other crops. The IPM IL has consistently focused on biological control of FAW since its involvement, as this approach can tackle this pest not only on maize but also on other crops, and additionally, it can suppress the pest on a farm, village, province, country, or regional basis depending upon the effort and resources that are made available. Further, it is compatible with joint application with all other IPM tactics in the field, except that of chemical pesticides, which would most likely impede processes using biological control. The IPM IL, in collaboration with icipe and ICRISAT-Niger, has identified egg parasitoids – Trichogramma spp. and Telenomus remus – and some larval parasitoids which attack FAW in Africa. It is known that these parasitoids are amenable for augmentative biological control and they are being used in augmentative biological control of FAW in the Caribbean and South America. This publication provides information on rearing and release of these parasitoids under African conditions. The IPM IL, icipe, and ICRISAT-Niger have already jointly conducted two workshops for participating countries in Africa and Asia.
