the carabid beetle pterostichus (phonias) strenuus (panzer) is newly recorded from iran. it was collected by hand from ghaleroudkhan forests in the caspian province of guilan. this carabid beetle is widely distributed throughout the palaearctic region including europe, uzbekistan, kazakhstan and russian far east.

ptinidae or spider beetles, is a worldwide family of beetles especially distributed in the subtropical and temperate zones including iran. niptus holoeucus (golden spider beetle) from kangohar cave in fars province (iran) is described as new record for iran. we regarded this beetle as a troglophile and guanophile species.

fumigant toxicity of various doses of essential oils (185.2, 370.4, 555.5, 740.7, 925.4, 1111.1, and 1296.3 µl/l water) from five officinal plants, including rosemary (rosmarinus officinalis), lavender (lavandula vera), fennel (foeniculum vulgare), tarragon (artemisia dracunculus)and summer savory (satureja hortensis)on two stored products pests, cowpea weevil (callosobruchus maculatus) and red...

Extensive mortality of whitebark pine, beginning in the early to mid-2000s, occurred in the Greater Yellowstone Ecosystem (GYE) of the western USA, primarily from mountain pine beetle but also from other threats such as white pine blister rust. The climatic drivers of this recent mortality and the potential for future whitebark pine mortality from mountain pine beetle are not well understood, y...

A novel approach to Bayesian Reinforcement learning (RL) named Beetle has recently been presented; this approach nicely balances exploration vs. exploitation while learning is performed online. This has produced an interest into experimental results obtained from the Beetle algorithm. This thesis gives an overview of bandit problems and modi es the Beetle algorithm. The new Beetle Bandit algori...

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...
