Cereals grains, in general and maize, in particular play a vital role in the eating regimen of useful resource poor folks of sub Saharan Africa (SSA), together with Ethiopia. Nonetheless, each quantitative and qualitative losses of those meals grains by insect pests in storage have been indicated to be one of many vital components that have an effect on the familys meals safety (Abebe et al., 2009; Worku et al., 2012; Manandhar et al., 2018; Hiruy and Emana, 2018).
Maize weevil, Sitophilus zeamais and Tribolium castaneum, crimson flour beetle, respectively are among the many most harmful main and secondary pests which are accountable meals insecurity ruler poor (Srivastava and Subramanian, 2016; Hiruy and Emana, 2018). Administration of those insect pests has been primarily dependent upon artificial chemical pesticides and fumigants that have been typically related adversarial results on useful and non-target organisms, environmental prolusion in addition to well being danger to human (Karakas, 2016). These conditions of artificial pesticides impressed the seek for comparatively secure, environmentally sound and promising various management choices equivalent to botanicals that might be simply and much less expensively produced at farmers and small scale industries degree (Dubey et al.
, 2008; Nikkon et al., 2009; Karunaratne and Karunaratne, 2018).
One of many fundamental causes that botanicals have been used historically utilized by farmers beneath their grains storage is their repellent impact on insect pests from their saved grain. Repellents refers to chemical substances of crops that push away the insect pests from supplies handled by them by means of motivating the olfactory or different receptors of the bugs, inflicting much less impact on the atmosphere (Jahromi et al 2012; Karunaratne and Karunaratne, 2012). Botanicals have been thought of to be secure as they pose minimal impression to the atmosphere and human well being in addition to they decrease undesirable chemical residue on meals and meals grains that might be resulted from the use artificial chemical pesticides (Talukder et al., 2004; Talukder, 2006; Rajashekar et al., 2012). In addition to, the extracts of various elements of crops have been used in as repellant and protectants saved grains insect pests in completely different elements of the world (Ishii et al., 2010; Karunaratne and Karunaratne, 2012). Subsequently this examine was instated with goal evaluating the proportion repellency of six solvent extracts Militia feruginaea leaves towards the 2 most economically vital storage insect pests; the maize weevil, Sitophilus zeamais and the crimson flour beetle, Tribolium castaneu beneath laboratory situation.
