Bazı Biyolojik İnsektisitlerin Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae) Üzerindeki Etkileri
نویسندگان
چکیده
Bu çalışmada bitkisel bir insektisit olan Azadirachtin, bunun yanında entomopatojen fungus Verticillium lecani, Metarhizium anisopliae, Beauveria bassiana, Paecilomyces fumosoreus etken maddeli ticari preparatların Tribolium castaneum üzerindeki etkileri araştırılmıştır. Denemelerde biyolojik insektisitlerin önerilen dozları uygulanmış, 1, 3, 5, 7, 14 ve 21 gün sonra canlı-ölü bireyler sayılmış ölüm yüzdeleri hesaplanmıştır. işlemden Abbott formülüne göre bu etki dereceleri belirlenmiştir. Sonuçlara göre; 21. günde yapılan sayımlarda sırasıyla %71.58, %42.11, %63.16, %53.68, %36.84 olarak hesaplanmıştır (Abbott). Elde edilen veriler incelendiğinde uygulanan (özellikle funguslar) bahsedilen zararlı üzerinde 14. günden itibaren etkili olmaya başladıkları saptanmış bunların kontrolünde kullanılabileceği kanısına varılmıştır.

Insecticidal efficacy of diatomaceous earth against Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae)
Laboratory bioassays were carried out to evaluate the insecticidal efficacy of SilicoSec? against 7 - 14 day old adults, old and young larvae of Tribolium castaneum (Herbst) with the mean ? SE (n = 30) weight of 3.4 ? 0.1 and 0.6 ? 0.1 mg, respectively at 27?C and 55 ? 5% RH. Wheat treated with four dose rates of SilicoSec? and untreated wheat served as a control with three replications. Adult?...
متن کاملOvicidal Activity of Essential Oils against Red Flour Beetle, Tribolium Castaneum (herbst) (coleoptera: Tenebrionidae)
Context: The essential oils are being tried as potential candidates for pest and disease management. Several essential oils of botanical origin have been reported for their repellant, toxic and developmental inhibitory activities. The ovicidal effect of essential oil is probably the major factor in the suppression of the development of adults from treated eggs. Objectives: To investigate the ov...

A strain of Tribolium castaneum (Herbst) was developed for resistance against deltamethrin, after six generation of selection from a laboratory susceptible strain, through topical application method. The selection was initiated at the dose 0.0004, which was increased during successive generations’ upto 0.026 in sixth generation. The resistance ratio of selected strain was determined, and it was...
متن کاملGenetic structure of Tribolium castaneum (Coleoptera: Tenebrionidae) populations in mills.
The red flour beetle, Tribolium castaneum (Herbst), is primarily found associated with human structures such as wheat and rice mills. Such structures are predicted to be spatially isolated resource patches with frequent population bottlenecks that should influence their genetic structure. Genetic diversity and differentiation among nine populations of T. castaneum collected from wheat and rice...
متن کاملA Family of Chemoreceptors in Tribolium castaneum (Tenebrionidae: Coleoptera)
Chemoperception in invertebrates is mediated by a family of G-protein-coupled receptors (GPCR). To date nothing is known about the molecular mechanisms of chemoperception in coleopteran species. Recently the genome of Tribolium castaneum was sequenced for use as a model species for the Coleoptera. Using blast searches analyses of the T. castaneum genome with previously predicted amino acid sequ...
