Abstract:
... AbstractMorphological characteristics, including male and female genitalia, combined with DNA barcodes were used to identify 470 Anaplecta specimens sampled from China. Ten Anaplecta species are new to science, including three cryptic species: A. paraomei Zhu & Che, sp. nov., A. condensa Zhu & Che, sp. nov., and A. longihamata Zhu & Che, sp. nov., which are distinguished mainly by their female ge ...

Abstract:
... The role of microbial decay and subterranean termites (Blattodea: Isoptera: Rhinotermitidae) in loss of litter mass was evaluated on the Joseph H. Williams Tallgrass Prairie Preserve (TGPP) of The Nature Conservancy in northeastern Oklahoma. Four field sites, each consisting of four blocks of land with each block sub-divided into two plots were established. Using in-ground baiting systems, termite ...

Abstract:
... The cave barklouse Psocathropos lachlani Ribaga, 1899 (Psocodea: Psyllipsocidae) occurs in many tropical and subtropical areas of the world, where it is a frequent dweller inside buildings. Numerous specimens of an egg parasitoid Dicopus psyche Girault, 1912 (Hymenoptera: Mymaridae) were collected by yellow pan traps and commercial cockroach sticky traps inside houses infested with P. lachlani in ...

Abstract:
... Termites can regulate the environment, including temperature and humidity, within their nests. In this study, we investigated the impact of environmental factors such as soil humidity, temperature, soil pH, and relative humidity on the ratio of workers to soldiers and the wood utilization rate of Coptotermes gestroi from their foraging activities. An environmental gauge was used three times every ...
... West Indian drywood termites (Cryptotermes brevis, Blattodea: Kalotermitidae) are an important invasive termite in many countries including Australia where they are spreading across two eastern states. Fumigation is often used to eliminate infestations, but it is costly, has negative environmental effects and does not prevent reinfestation. Heat treatment has been suggested as an alternative. Many ...

Abstract:
... Over the past few decades, species distribution modelling has been increasingly used to monitor invasive species. Studies herein propose to use Cellular Automata (CA), not only to model the distribution of a potentially invasive species but also to infer the potential of the method in risk prediction of Reticulitermes grassei infestation. The test area was mainland Portugal, for which an available ...

... Aiming at the sustainability of meat production, insects can replace traditional ingredients in the diet of poultry. Studies evaluating performance in birds have emerged to ensure this ability, but few address the health parameters of animals. This study was carried out to evaluate the effects of the inclusion of Madagascar cockroach meal in traditional diets on hematological and histopathological ...
... BACKGROUND: Photopharmacology is a fast‐growing photonics‐based technology, which realizes the high‐resolution regulation of drugs in time and space through light. The purpose of this research was to introduce photochromic groups into the isoxazoline structure to realize the regulation of γ‐Aminobutyric acid receptors (GABARs) targeting insect behavior. RESULTS: Azobenzene‐Fluralaner analogs ABF02 ...

Abstract:
... Effective active ingredients in toxicant bait formulations must be non-deterrent to insect feeding behavior at lethal concentrations. This study evaluated feeding deterrence for Coptotermes formosanus Shiraki, C. gestroi (Wasmann), and Reticulitermes flavipes (Kollar) when provided access to cellulose impregnated with various concentrations of the insect molting hormone, 20-hydroxyecdysone (20E). ...

Abstract:
... Small Tarachomantis Brancsik, 1893 (Dictyoptera: Mantidae) from Madagascar and the Comoros archipelago. With this work, the genus Tarachomantis Brancsik, 1893, endemic of the Malagasy region, is fully revised after the study of about 550 specimens preserved in eleven scientific institutions and some private collections. It deals in particular with the smallers species, close to Tarachomantis caldw ...

Abstract:
... The nutritional properties of subterranean termite exuviae (shed exoskeletons) are not well-known because obtaining the large quantities necessary for investigation is difficult. A method for collecting large numbers of exuviae is reported here for the Asian subterranean termite, Coptotermes gestroi (Wasmann) (Blattodea: Rhinotermitidae), an invasive and economically important tropical termite spe ...

Abstract:
... With heat treatments to control drywood termites (Blattodea: Kalotermitidae), the presence of heat sinks causes heat to be distributed unevenly throughout the treatment areas. Drywood termites may move to galleries in heat sink areas to avoid exposure to lethal temperatures. Our studies were conducted in Crytotermes brevis-infested condominiums in Honolulu, Hawaii to reflect real-world condominium ...

Abstract:
... Scorpion α-toxins bind at the pharmacologically-defined site-3 on the sodium channel and inhibit channel inactivation by preventing the outward movement of the voltage sensor in domain IV (IVS4), whereas scorpion β-toxins bind at site-4 on the sodium channel and enhance channel activation by trapping the voltage sensor of domain II (IIS4) in its outward position. However, limited information is av ...

Abstract:
... Symbiotic associations underlie hierarchical evolutionary transitions being crucial to understanding biological complexity. But which proximate triggers promote the first successful contact between guests and their hosts? We tackle this problem, studying the macro-symbiotic model system comprised by two termite species (Blattodea: Isoptera) cohabiting termitaria as a host and its obligatory inquil ...

Abstract:
... Linear and geometric morphometrics approaches were conducted to analyze the head capsule (HC) shape of collected soldier caste specimens of Coptotermes from various locations in Indonesia. The soldiers’ morphology was observed and measured. The results of the principal component analysis of the group of all species showed two important groups of variables, i.e., the body size and setae characteris ...

Abstract:
... In the eastern United States, there are nine species of subterranean termites in three genera: Reticulitermes (six species), Coptotermes (two species), and Prorhinotermes (one species). These species serve as important ecological players by decomposing cellulose material, and some are important structural pests. Many of these species are difficult to discriminate morphologically and require examin ...

This work assesses damage caused by Coraebus undatus (Fabricius) (Coleoptera: Buprestidae) and Reticulitermes grassei Clément (Blattodea: Rhinotermitidae) in managed cork oak forests from the southern Iberian Peninsula. Lesions were diagnosed and quantified in relation to the following features: height and orientation in the trunk, diameter at breast height, solar exposure, understory presence and ...
... Most of our knowledge on insect cuticular hydrocarbons (CHCs) stems from analytical techniques based on gas-chromatography coupled with mass spectrometry (GC-MS). However, this method has its limits under standard conditions, particularly in detecting compounds beyond a chain length of around C40. Here, we compare the CHC chain length range detectable by GC-MS with the range assessed by silver-ass ...
