  • The legume pod borer, Maruca vitrata Fabricius (Lepidoptera: Crambidae), an important insect pest of cowpea: a review emphasizing West Africa
    International Journal of Tropical Insect Science, 2019
    Co-Authors: J. E. Huesing, Barry R Pittendrigh, Manuele Tamo, C. L. Dabiré-binso, L. L. Murdock
    Abstract:

    The legume pod borer Maruca vitrata Fabricius (Lepidoptera: Crambidae) is a pantropical insect pest of legumes. In West Africa M. vitrata is the most devastating insect pest of cowpea, a food crop providing much-needed, inexpensive protein to farmers and consumers. Various approaches to controlling this pest have been tried, including cultural management, host plant resistance and use of synthetic and botanical pesticides, all with limited success. In this review we present information on the distribution, morphology, molecular characteristics, behavior and host plants of M. vitrata . We give especial attention to innovative management tactics being developed for West Africa, including genetically engineered Bt cowpea, new biopesticides and use of exotic parasitoids. We discuss research needs for enhancing integrated pest management (IPM) for M. vitrata in Africa.

  • influence of rearing substrates and nontarget hosts on the bionomics of the tachinid parasitoid nemorilla maculosa diptera tachinidae

    Abstract:

    The tachinid Nemorilla maculosa Meigen (Diptera: Tachinidae) was introduced from Taiwan to Benin for evaluating its potential as a biocontrol candidate against the cowpea pest Maruca vitrata (Fabricius) (Lepidoptera: Crambidae). To optimize its rearing, we assessed the influence of M. vitrata larval age and rearing substrate-cowpea germinating grains and peabush leaves-on its life table parameters, while its host specificity was investigated with regard to nontarget effects. Parasitism rates were higher when older larvae (10- and 14-d old) were offered to females of N. maculosa compared to the younger (2-, 4-, and 6-d old) host larvae. Regardless of the rearing substrate, development time was longer for females than males, and females lived longer than males irrespective of the age of the host. Sex ratio did not vary significantly with host ages or rearing substrate. The average number of eggs laid by a female reared from M. vitrata larvae feeding on cowpea germinating grains or peabush leaves was 94.2 ± 4.38 and 71.9 ± 1.70 eggs, respectively. The host suitability of N. maculosa was assessed by testing four nontarget Lepidoptera species: Spodoptera littoralis Boisduval (Lepidoptera: Noctuidae), Sesamia calamistis Hampson (Lepidoptera: Noctuidae), Corcyra cephalonica (Stainton) (Lepidoptera: Pyralidae), and Eldana saccharina Walker (Lepidoptera: Pyralidae). Larvae of S. littoralis and C. cephalonica were successfully parasitized while N. maculosa did not develop in the larvae of E. saccharina and S. calamistis although they were parasitized. Despite the potential of N. maculosa as a biological control agent against the pod borer M. vitrata, more detailed nontarget studies, extending to other native Crambidae species, are needed before making decisions on field releases.

Örneklemeler, her tarlanın 5 farklı noktasında aynı sıra üzerinde 5 farklı bitki kontrol edilerek yapılmıştır. Çalışmalar süresince toplam 1404 larva toplanmış ve laboratuvarda kültüre alınarak erginleri elde edilmiştir. Sonuçta, Lepidoptera takımına ait Agrotis ipsilon Hufnagel, Spodoptera exigua (Hübner), Acantholeucania loreyi (Duponchel), Helicoverpa armigera (Hübner) (Noctuidae) ve Ostrinia nubilalis (Hübner) (Crambidae) türleri elde edilmiştir. Bu türlerin populasyon içerisindeki dağılımları A. ipsilon % 0.93, H. armigera % 30.5, S. exigua % 27.9, A. loreyi % 34.1 ve O. nubilalis % 6.6 olarak belirlenmiştir. Bu türlerden S. exigua birinci ve ikinci ürün mısır bitkisinde, H. armigera ve O. nubilalis ise ikinci üründe zararının önemli olabileceği bulunmuştur. Ayrıca, bu çalışma ilk defa Iğdır ili mısır alanlarında yürütülmüştür.This study was carried out in first and second crop corn fields in order to determine the lepidopterous pest species in 29 corn fields of Iğdır province of East Anatolia Region in 2013-2014 years. In this study was applied in visual inspection method. The sampling were done in 5 adjacent plants on the same row in 5 different points of field. During studies, a total of 1404 larvae were collected and their adults were reared at the laboratory. As a result of study, Black cutworm, Agrotis ipsilon Hufnagel, Beet armyworm, Spodoptera exigua (Hübner), Loreyi leafworm, Acantholeucania loreyi (Duponchel), Cotton bollworm, Helicoverpa armigera (Hübner) (Noctuidae) and European corn borer, Ostrinia nubilalis (Hübner) (Crambidae) were determined. The rate of the species in the composition of these lepidopterous species, as A. ipsilon 0.93%, H. armigera 30.5%, S. exigua 27.9%, A. loreyi 34.1%, O. nubilalis 6.6% were found. It was found S. exigua damaged in the first and second crop and H. armigera and O. nubilalis in second crop. In addition, this study has been the first study on corn pests in Iğdır province
