The aim of the present work was to study bioactivity lemon, orange, and grapefruit peel essential oils (EOs) obtained from Argentinian plantations on different agronomically important insect fungal species. chemical profile EOs determined by Gas Chromatography-Mass Spectrometry (GC/MS); insecticidal activity studied through contact fumigant assays; antifungal evaluated with tests. Orange EO mos...

An economic evaluation of newly developed methods for disinfesting empty grain storage bins by heat treatment will be a useful tool for decision-making by grain storage managers. An economic empirical model of heat treatment and chemical applications was developed using minimization of costs at a target risk level associated with the grain-damaging insects Tribolium castaneum (Herbst), Sitophil...

This study was carried out to determine the post-treatment efficacy of three local Beauveria bassiana isolates by applying them against adults common stored-product pests, Sitophilus oryzae L. (Coleoptera: Curculionidae) Rhyzopertha dominica F. (Col.: Bostrichidae) and Oryzaephilus surinamensis Silvanidae). 
 For biological tests, wheat grains were mixed with fungal spores at 1000 ppm (w/w...

In this study, laboratory experiments were conducted in order to assess the insecticidal and repellency effects of a novel Turkish diatomaceous earth (DE) formulation (Detech) on adults rice weevil, Sitophilus oryzae (L., 1763) (Coleoptera: Curculionidae), confused flour beetle, Tribolium confusum du Val., 1863 Tenebrionidae), lesser grain borer, Rhyzopertha dominica (F., 1792) Bostrichidae). F...

Abstract Background Botanical pesticides may be a possible solution to the post-harvest loss of stored grains faced by farmers and food processors. In this study, seed preservatives properties Secamone afzelii leaves extracts at 50, 100, 150, 200 µl concentrations were investigated against lesser grain borer Rhyzopertha dominica (Fabricus) infestation on wheat weight germination capability arra...
