Efficacy of Different Combination of Insecticides against Cowpea Pod Borer in Cowpea [Vigna ungiculata (L.) Walp.]

Development and validation of integrated pest management modules against spotted pod borer Maruca vitrata Fabricius on garden bean Lablab purpureus var. typicus (L.)

“…30 (Naik et al, 2019). The insecticidal combination of imidachloprid 17.8 SL @ 0.005 % + spinosad 45 SC @ 0.009 % recorded the lowest number (1.18 larva / plant) of larval population of spotted pod borer in cowpea (Kattula et al, 2018). Reddy and Hampaiah (2018) reported that the insecticidal mixture, lamda cyhalothrin 4.6 % + chlorantraniliprole 9.3 % ZC was superior in reducing the larval population of M. vitrata in cowpea even after 15 days of spraying.…”

Comparative effects of three levels of insect infestation on selected properties of five Nigerian cowpea (<i>Vigna unguiculasta (L.</i>) walp) varieties

“…It is also used as composite flour in the production of infant foods and baked and fried products such as bread, cake and chin-chin where they improve especially the protein quality of the products (Uzogara and Ofuya, 1992;Akubor, 2004;Oladunmoye et al, 2010;Vilakati et al, 2015).Unfortunately, cowpea is prone to heavy field and post harvest infestation damage and this constitutes one of the major constraints to its optimal utilization as food as well as limits its contribution to food security (Kungu et al, 2003). Cowpea is attacked in the field where yield reductions of 20 to over 90% by the field insect pests such as Megalurothrips sjostedti, Aphis craccivora, Helicoverpa armigera and Maruca vitrata has been reported in Cameroun and Nigeria and in some other producing countries (Carlos, 2004;Ngakou et al, 2010;Muchero et al, 2010;Margam et al, 2011;Abudulai et al, 2016;Sangoyomi and Olufunmilola, 2016;Alale et al, 2017;Kattula et al, 2017). Cowpea is further severely damaged in the store by the foremost cowpea storage pest, the cowpea weevil Callosobruchus maculatus Fab.…”
