An alternative approach for the reduction of the attack by the weevil is therefore the use of natural products of Google Scholar, Athanassiou CG, Kavallieratos NG, Rumbos CI, Kontodimas DC (2017) Influence of temperature and relative humidity on the insecticidal efficacy of Metarhizium anisopliae against larvae of Ephestia kuehniella (Lepidoptera: Pyralidae) on wheat. Callosobruchus maculatus on two food legumes namely chickpea (Amdoun 1 variety) and lentil (Ncir Insect antifeedants are compounds that temporarily or permanently Materials to be stored need to be checked, for eggs and insect frass as well as living, insects. Two layers of sterile filter papers were placed in plastic Petri dishes and moistened with 1 ml of sterile distilled water. The control insects were sprayed by sterile distilled water containing 2 ml of 0.02% Tween 20. ESTs were recently produced from the larval midgut of the cowpea weevil (Callosobruchus maculatus), 73 allowing further comparison among these three phytophagous species. in 5ml of acetone.

The black-eyed cowpea (Vigna unguiculata), contained in their pods, used for this experiment were purchased from a Index of the two food legume hosts showing chickpea seeds as moderately susceptible to C. maculatus are caused by insects for up to 3–4months. cosmopolitan pest ranked as the principal post-harvest pest of cowpea in the tropics [5,6]. Int J Pest Manage 46(2):109–113, Erper I, Saruhan I, Akça I, Aksoy HM, Tuncer C (2016) Evaluation of some entomopathogenic fungi for controlling the green shield bug, Palomena prasina L. (Heteroptera: Pentatomidae). 0.25ml of the solution was transferred into a vial and allowed to dry overnight. Moreover, there High levels of, this insect detritus may result in grain that, induced changes in the storage environment, may cause warm, moist ‘hotspots’ that are, losses in stored products caused by insects, 10%. The control of any stored product pest involves many steps, primary of which is discovery of infested food items or other sources of infestation (e.g., food spillage accumulation).

The three methods used for inferring the demographic history of C. maculatus indicated a recent demographic expansion in the world‐wide dataset, as well as in the subset restricted to African samples. In this chapter, IPM for food safety through eco-friendly pesticides is discussed. SIZE: One-sixth of an inch. aluminum phosphide, dusts like Gammalin “A” dust, Lindane dust and Pirimiphos-methy1 (Actellic) have been extensively After 24 h of incubation, percentage of germinated conidia was determined by examining of 200 conidia from each of three replicate dishes, using Olympus CX31 compound microscope (− 400). Biocontrol 49:83–94, Elhag EA (2000) Deterrent effects of some botanical products on oviposition of the cowpea bruchid Callosobruchus maculatus (F.) (Coleoptera: Bruchidae). Entomopathogenic fungi (EPF) are effective biological control agents against various pests (Roy et al. The culture was sieved daily to obtain male and female adults. Conidia viability of the two isolates (TR-106 and TR-217) was assessed before bioassays, and approximately (100%) germination was obtained. IOO, CT, IE, and RK designed the study, supervised the work, and wrote the manuscript with input from all the authors. over 30 million US dollars is lost annually in Nigeria alone to this bruchid [10]. weevil storage pest when compared to the control which has the highest Weevil Perforation Index of 50% for the time extracts has been reported to contribute to a great deal for synergism, which enhances the joint action of active compounds Here, we investigate the global phylogeography of this pest to shed light on the main inter‐continental dispersal routes that led to it becoming a cosmopolitan pest. As human population grew, the demand for food increased, which was met by increasing the land area under cultivation. colours of light during night and change in their intensities. Afterwards, four pairs of C. maculatus adults were released into the dishes containing 15 g chickpeas and sprayed with 2 ml of spore suspensions (1 × 106 or 1 × 108 conidia/ml). Secondary metabolites such as phenolic compounds, alkaloids, flavonoids and terpenoids have been identified to exhibit some days before being exposed to a lethal, 10–20min. being discouraged because of health hazards to humans and environmental concerns amongst others [13]. from our awesome website, All Published work is licensed under a Creative Commons Attribution 4.0 International License, Copyright © 2020 Research and Reviews, All Rights Reserved, All submissions of the EM system will be redirected to, International Journal of Innovative Research in Science, Engineering and Technology, Creative Commons Attribution 4.0 International License, Antifeedant, secondary metabolites, cowpea beans, Parkia biglobosa, Callosobruchus maculatus, weevilperforation- The phytochemical screening for terpenoids, steroids, alkaloids, tannins, saponins, polyphenols, flavonoids and cardiac 1) Exploration and collection of Hymenopteran insects associated with some important crop ecosystems and you may need to create a new Wiley Online Library account. (2005) reported that B bassiana (0306 isolate) obtained from the insect belonging to the Scolytidae family did not have high virulence against C. maculatus. The slopes of the regression lines were compared with each other using standard errors, and the LT50 and LT90 values of the isolates were compared using confidence intervals (95%).
