N Mashaya N Mashaya
Tobacco processing practices of humidifying rooms with mist and using steam to soften cured leaf, raise relative humidity (r.h.) and temperature in the rooms during February to March, creating conditions suitable for Liposcelis entomophila ...
Cross-resistance of a chlorpyrifos-methyl resistant strain of Oryzaephilus surinamensis (Coleoptera: Cucujidae) to fumigant toxicity of essential oil extracted from Eucalyptus globulus and its major monoterpene, 1,8-cineole [0.03%]
S Lee,W Choi,H Lee et al. S Lee et al.
The fumigant toxicities of eucalyptus essential oil and 1,8-cineole, the major component of eucalyptus oil, were tested against a chlorpyrifos-methyl resistant strain and a reference strain of the sawtoothed grain beetle, Oryzaephilus surin...
The influence of storage practices on aflatoxin contamination in maize in four agroecological zones of Benin, west Africa [0.03%]
K Hell,KF Cardwell,M Setamou et al. K Hell et al.
Aflatoxin level in 300 farmers' stores in four agro-ecological zones in Benin, a west African coastal country, were determined over a period of 2 years. At sampling a questionnaire was used to evaluate maize storage practices. Farmers were ...

Essential oils were extracted from four West African plant species [Tagetes minuta (Family Compositae), Hyptis suaveolens (Family Labiatae), white basil Ocimum canum (Family Labiatae), and sweet basil O. basilicum (Family Labiatae)] by stea...
Field monitoring Sitophilus zeamais and Sitophilus oryzae (Coleoptera: Curculionidae) using refuge and flight traps baited with synthetic pheromone and cracked wheat [0.03%]
PW Likhayo,RJ Hodges PW Likhayo
Flight traps with open vertical baffles and refuge traps in the form of rectangular cardboard boxes were used to catch Sitophilus zeamais and S. oryzae in Kenya. Traps baited with the aggregation pheromone (Sitophilure), and for the first t...
Volatiles as an indicator of fungal activity and differentiation between species, and the potential use of electronic nose technology for early detection of grain spoilage [0.03%]
N Magan,P Evans N Magan
There is significant interest in methods for the early detection of quality changes in cereal grains. The development of electronic nose technology in recent years has stimulated interest in the use of characteristic volatiles and odours as...

Wheat infested with grain mites (Acari) and Sitophilus granarius, and maize infested with Prostephanus truncatus, were exposed to hot air in a CIMBRIA HTST Microline toaster((R)). Inlet temperatures of the hot air were in the range of 150-7...
Resistance and some enzyme activities in Liposcelis bostrychophila Badonnel (Psocoptera: Liposcelididae) in relation to carbon dioxide enriched atmospheres [0.03%]
J Wang,Z Zhao,JH Tsai J Wang
Two populations (S-1 and S-2) of the psocid, Liposcelis bostrychophila Badonnel were exposed to carbon dioxide enriched atmospheres. Carbon dioxide resistance developed at steady rates in these two populations during this study period. Sele...

Sorting of dried figs prior to inspection is labor-intensive and somewhat complex. We examined the potential of using near-infrared spectroscopy (NIRS) to automate sorting of dried figs. Calimyrna and Adriatic types were inspected by hand u...
Development-inhibiting activity of some tropical plants against Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae) [0.03%] 几种热带植物对玉米象的发育抑制活性（鞘翅目：象甲科）
MA Haque,H Nakakita,H Ikenaga et al. MA Haque et al.
Thirteen tropical plants were evaluated for development-inhibiting activity against Sitophilus zeamais. The bioassays were carried out by incorporating seeds or leaves at various dose levels into an artificial diet for the test insect. It w...
