Modified atmospheres present a residue-free alternative to fumigants for controlling postharvest pests of grain during storage. How sub-lethal applications of this method affects the reproductive fitness of target pests, however, is still not fully understood. We examined how low levels of ambient oxygen influence the reproduction of the female cowpea bruchid (Callosobruchus maculatus), a pest ...

Susceptibility of Lasioderma serricorne (F.) (Coleoptera: Anobiidae) Life Stages to Elevated Temperatures Used During Structural Heat Treatments Authors: C. Yu, B. Subramanyam, P.W. Flinn, J.A. Gwirtz Submitted to: Journal of Economic Entomology Methyl bromide is still widely used in food processing and storage facilities for the suppression of storedproduct insect pests, but its use is schedul...

This study was conducted at the Department of Crop Science and Technology Research farm, Federal University of Technology, Owerri, during 2010 cropping season. The experiment was laid out in Randomized Complete Block Design. The plant extracts were tested at four rates (0.00, 1.00, 2.00 and 3.00 ml/ plot), and Pirimiphos-methyl (Actellic 25 E. C) at the rates of 1.25, 2.50 and 3.75 ml/ plot. Th...

Allergy – diagnostics – cockroach – tick – storage mite – arthropod Cockroach, tick, storage mite and other arthropod allergies: Where do we stand with molecular allergy diagnostics? Abstract Arthropods form a broad phylum within the animal kingdom, comprising widely varying members such as insects, arachnids, crabs and centipedes. In addition to common allergies to house dust mites or hy-menop...

T. HE AIRPLANE holds a bright new hope in the farmers' uphill struggle with insects. Since 1922, when Department engineers and entomologists developed a practical method for dusting cottonfields with calcium arscnatc to protect the crop against the boll weevil, commercial airplane dusting has become routine, particularly in cultivated fields that spread over a wide area unbroken by trees or shr...

Pest index, a new approach to categorizing the threat posed by an organism to woody plants, is proposed to assist plant managers in establishing treatment thresholds for pests of woody plants. The need for such a tool is based on the incredible diversity of pests of woody plants and the lack of experimental data establishing such thresholds. The pest index is computed using information about th...

Insect infestation during the storage of cowpea is a major challenge among smallholder farmers in sub-Saharan Africa (SSA). Farmers use various postharvest methods to deal with insect pests, including insecticides, which may result health and environmental hazards. Four hundred (400) were interviewed on their perceptions preference different Northern Ghana. About 58% applied 50% used ash, 42% h...

Arthropods form a broad phylum within the animal kingdom, comprising widely varying members such as insects, arachnids, crabs and centipedes. In addition to common allergies to house dust mites or hymenoptera venom, there are also rarer allergies that can be attributed to three major sources of allergens: cockroaches, ticks and storage mites. Other less known allergen sources include spiders, m...

In the long run, this holistic approach to dealing with pests should reduce pesticide use, provide economic savings for the farmer and protect both the environment and human health. The term ‘integrated’ implies incorporation of natural enemy/antagonist levels into decision-making, and use of compatible, non-disruptive tactics that preserve these agents. Integration can be viewed as either vert...

High carbon dioxide concentrations can effectively control most storage pests. To estimate the toxicity effect of high CO2, four different CO2 (25% 50% 75% and 95% CO2) were used to treat Tribolium castaneum, biochemical (carbohydrate content gene expression level) physiological (mortality, pupation, eclosion rate, weight) features insects submitted treatments with evaluated. The T. castaneum m...
