Abstract The effect of four concentrations (0, 3, 1, 5%) the nanopesticide neem leaf extract was tested on stages hairy grain beetle at five time times (1, 2, 5, 7) days. results showed that there is Significant differences between three 5) compared to fourth concentration, which represents control treatment, where it noted hatching rate egg stage lowest 5% concentration. As for larva and pupal...

background: the main object of this experimental work was to practise laboratory production both adult and the larval stage of hymenolepis diminuta with conventional modification to make further studies easier. materials & method: adults h. diminuta were collected from urban rats in tehran, iran. the beetles became infected using blended gravid segments with flour as bait. cysticercoids have be...

the meloidae, known as blister beetles, a widespread family of tenebrionoidea that includes approximately 2500 species, is still scarcely known faunistically in several areas of the world. because of specific biogeographical feature, iran harbors a rich diversity of meloids and due to the lack of basic and integrated studies, particularly in eastern parts of iran, our current knowledge of irani...

The Getty Conservation Institute and the J. Paul Getty Museum have been studying the use of low oxygen atmospheres using nitrogen for pest eradication. Earlier work by Nieves Valentin and Frank Preusser found that a 30-hour exposure to an atmosphere of 0.5% oxygen and 99.5% nitrogen killed all life stages of the fruit fly (Drosophila melanogaster) [1]. In a collaborative project at the Universi...

The western pine beetle, Dendroctonus brevicomis LeConte (Coleoptera: Curculionidae: Scolytinae), is a major cause of ponderosa pine, Pinus ponderosa Dougl. ex Laws., mortality in much of western North America. This study was designed to quantify relationships between western pine beetle trap catches [including those of its primary invertebrate predator Temnochila chlorodia (Mannerheim) (Coleop...

The red flour beetle (Tribolium castaneum) is a major pest of stored grain and grain products and a popular model species for a variety of ecological, evolutionary, and developmental biology studies. Development of a linkage map based on reproducible and highly polymorphic molecular markers would greatly facilitate research in these disciplines. We have developed a genetic linkage map using 269...

Mani, S., Muir, W.E., Jayas, D.S. and White, N.D.G. 2001. Computer modelling of insect-induced hot spots in stored wheat. Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 43:4.74.14. A computer model of insect-induced hot spots in stored wheat was developed by combining four submodels: (1) a three-dimensional, finite element model of heat transfer, (2) a population dynamics mo...

Widespread tree mortality caused by outbreaks of native bark beetles (Circulionidae: Scolytinae) in recent decades has raised concern among scientists and forest managers about whether beetle outbreaks fuel more ecologically severe forest fires and impair postfire resilience. To investigate this question, we collected extensive field data following multiple fires that burned subalpine forests i...
