Depolanmış ürün zararlıları, tarım ürünlerin depolama sürecinde hasat sonrası ciddi kayıplara neden olan en önemli biyotik faktörlerden biridir. Bu zararlılar ile mücadele amacıyla yıllardır yaygınlıkla pestisitler kullanılmaktadır. Ancak pestisitlerin ve ne olduğu kalıntıların hedef dışı organizmalar üzerinde oluşturduğu toksik etkiler bilinmektedir. nedenle, alanlarında biyolojik mücadelede y...

The active spread of tuberculosis around the world has been an urgent issue for many decades, but even now, there is no data on all available methods introducing pathogen into a previously healthy territory and mechanisms mycobacteria activity, this makes it impossible to eradicate disease completely. purpose study was determine effect rice weevil (lat. Sitophilus oryzae) dissociative forms myc...

The insecticidal pyrazole ethiprole, applied at rates of 7.5 and 10.0 ppm either alone or in combination treatments with deltamethrin, piperonyl butoxide, and chlorpyrifos-methyl, was evaluated as a protectant of stored wheat and stored corn. The commodities were treated with six treatment combinations, including an untreated control, and held for 6 mo at 22, 27, or 32 degrees C and 57% RH. Bio...

Ethyl formate (EtF) is being evaluated as a fumigant for the rapid disinfestation of grain, including a cylinderised mixture of EtF in carbon dioxide (16.7% by weight), VAPORMATETM, formulated by BOC Ltd. Insect mortality achieved with a 3-hour dynamic (forced-flow) application versus a static application of the EtF formulation was investigated. In the dynamic application, gaseous VAPORMATETM w...

J. Econ. Entomol. ii: 1144-1148 (1984) ABSTRACT Seed oils of many sapindaceous plants contain substantial amounts of cyanolipids. Several of these oils stimulated aggregation of the sawtoothed grain beetle, Oryzaephilus surinamensis (L.), and the confused flour beetle, Tribolium confusum (Jacquelin duVal). In a pitfall bioassay, they attracted the sawtoothed grain beetle and the rice weevil, Si...

Certain strains of the fungi Aspergillus flc~rus and A. parasitic-us produce a group of mycotoxic metabolites commonly known as the aflatoxins (Diener and Davis, 1969). The aflatoxins have been studied extensively since they were found first in peanuts, stored grains, and other agricultural products (Golumbic and Kulick, 1969). Aflatoxin B, (AFB,) is a known hepatocarcinogen and hepatotoxic age...

We examined the insecticidal effect of three different dust formulations, which were attapulgite (W), mix with oregano essential oil 52% carvacrol (D1), and 75% (D2), in four major stored-product beetle species, Sitophilus oryzae (L.), Tribolium confusum Jacquelin du Val, Rhyzopertha dominica (F.), Trogoderma granarium Everts. was most susceptible at all followed by T. R. dominica. In contrast,...

In the present study, we investigated the fumigant potential of five edible essential oils (EOs) against Sitophilus oryzae and their phytochemical residues in treated grains. Among the tested EOs, peppermint oil proved significantly effective (P ≤ 0.05) on S.oryzae at 400 μl/L air concentration, inducing 83 and 100% mortalities in with-food and without-food conditions respectively over 72 h exp...
