Hoyle (i960) has recently shown that carbon dioxide has a direct action on the closer muscle of spiracle 2 of the desert locust, Schistocerca gregaria Forskal, reducing the electrical responses and the tension developed. Nevertheless, except in flight, the valve movements are nearly always synchronized with ventilation, and it seems unlikely that this action of carbon dioxide plays much part in...

Dragonfly Anax nigrofasciatus Oguma, 1915 (Odonata: Aeshnidae) was collected on a small pond in the vicinity of Vityaz settelment, Gamov Peninsula, Primorsky Krai 2021. It is first record this East Asian species from Russia. A. clearly differs parthenope julius Brauer, 1865, more common south Russian Far East, by body coloration and details morphology.

An unusual new genus of Scenopinidae, Iranotrichia gen. n., comprising two newly discovered species (Iranotrichia insolitasp. n. and Iranotrichia nigrasp. n.), is described from Iran. Iranotrichiagen. n. are scenopinine window flies with a habitus reminiscent of certain bee fly genera (Bombyliidae), based on colouration and elongate mouthparts and antennae. The phylogenetic placement of this di...

Polymerase chain reaction analysis was performed to determine whether mosquito predators in wetland habitats feed on Anopheles gambiae sensu lato (s.l.) larvae. Aquatic mosquito predators were collected from six wetlands near Lake Victoria in Mbita, Western Kenya. This study revealed that the whole positive rate of An. gambiae s.l. from 330 predators was 54.2%. The order of positive rate was th...

We prepared a consolidated list of edible and therapeutic insects used in Arunachal Pradesh (N.E. India) by two tribal societies (i.e., the Nyishi of East Kameng and the Galo of West Siang). The list is based on thorough, semi-structured field-interviews with 20 informants of each tribal group. At least 81 species of local insects, belonging to 26 families and five orders of insects, namely Col...

West Lombok District is the second largest district in Islands. The diversity of dragonflies (Order Odonata) as a bioindicator environmental quality has not been widely studied region. This study aimed to determine species found Batubolong River, and its relation occurring land cover changes. was carried out by using descriptive explorative method, where sampling technique done means line trans...

Abstract Increased metal concentrations in aquatic habitats come as a result of both anthropogenic and natural sources. Emerging insects that play an indispensable role these environments, transferring resources energy to higher trophic levels terrestrial habitats, may inadvertently also act biovectors for metals other contaminants. This study measured 22 different detected biofilm, life stages...

A short investigation was devised by Department of Agricultural Entomology, Tamil Nadu University, Coimbatore in 2022 to document the arthropod composition sugarcane (Saccharum officinarum L.) ecosystem. Arthropod fauna collected from ecosystem farmers’ field at Puthur district, weekly intervals. Totally, 2,310 individuals subclass Pterygota were and among them most specimens belonged Exopteryg...
