Abstract Stored-product insects in rice are threats to the quality and quantity of stored rice. One methods monitor storage facility is using an ultraviolet (UV) light trap. This study aimed investigate species diversity abundance trapped UV traps government’s Makassar City, Indonesia. was conducted a maintained by Indonesian Bureau Logistics (Bulog) Panaikang early October 2022. Six (4 watts) ...

the purpose of this research was to determine the effect of modified atmosphere packaging (map) containing high carbon dioxide gas concentrations on the quality of sayer dates, to be used as a safe alternative to methyl bromide fumigation. different percentages of gases (85% co2 + 3% o2 + 12% n2; 75% co2 + 12% o2 + 13% n2; 34% co2 + 37% o2 + 29% n2) were injected into the cellophane packages. t...

Hard red winter wheat was treated with pirimiphos-methyl at 4, 6 and 8 mg kg(-1), synergized pyrethrins at 0.38, 0.75, 1.13 and 1.5 mg kg(-1), and combinations of the two insecticides, to conduct laboratory bioassays against four beetle pests of stored grain, red flour beetle Tribolium castaneum (Herbst), rusty grain beetle Cryptolestes ferrugineus (Stephens), lesser grain borer Rhyzopertha dom...

The egg production and development of Amphibolus venator (Klug) were investigated at five temperatures (25, 27.5, 30, 32.5 and 35°C), 70% r.h. and 16L–8D photoregime. The optimum temperature for multiplication and development of A. venator was around 32.5°C. Pre-oviposition period decreased with increasing temperature. Temperature in the range 25–35°C had no effect on oviposition period. The av...

A granary trial was conducted to evaluate the efficacy of protein-enriched pea flour against three common stored-grain insects, Sitophilus oryzae (L.), Tribolium castaneum (Herbst), and Cryptolestes ferrugineus (Stephens). Six 30-t farm granaries were filled with approximately 11 t of barley. The barley was either not treated, treated with protein-enriched pea flour at 0.1% throughout the entir...

Stored-product insects often live in an environment of spatially separated food patches that vary considerably in size, quality, and persistence. The movement of individuals among patches of food influences the probability that stored products will become infested and pest populations will persist within storage facilities, thus affecting many aspects of pest management. We examined how a major...
