Abstract:
... Identification key represents a powerful tool, which allows users to identify biological species, such as animals, insects, and plants. This key contains several steps leading to the corresponding species name. In this paper, we propose a new method for estimating insects' identification ease from their charecteristics values (CV). To realize that, we have investigated; 1- the variations of the id ...

Abstract:
... Insect odorant receptors (ORs) are believed to be a complex of an odorant binding subunit, OrX, and an ion channel forming subunit, Orco. In our previous study, we showed that the OrX subunit on its own in liposomes could detect volatile organic compounds (VOCs) ultrasensitively using Electrochemical Impedance Spectroscopy (EIS). In this study, we investigated the effect of the presence of Orco on ...

Abstract:
... Like most phytophagous insect pests, wireworms are suspected to use plant volatile organic compounds (VOCs) to locate appropriate host plants. Preliminary field observations at our study site showed strong differences in the infestation level of four varieties of maize by wireworms. We raised and tested the hypothesis that these maize varieties have differential susceptibility/attraction to wirewo ...

Abstract:
... In social insect colonies, individuals need to communicate to coordinate cooperative tasks and protect the colony and its resources against intruders. To maintain colony integrity, it can be particularly important to recognize nestmates and discriminate against non-nestmate conspecifics and heterospecific predators and parasites. As typical intruders are either con- or heterospecific adults, the m ...

The phylogenetic interrelationships among four hexapod lineages (Protura, Collembola, Diplura and Insecta) are pivotal to understanding the origin of insects and the early diversification of Hexapoda, but they have been difficult to clarify based on the available data. In this study, we identified 91 conserved microRNA (miRNA) families from 36 panarthropod taxa, including seven newly sequenced non ...

Abstract:
... BACKGROUND: RNA interference (RNAi) has potential as a pest insect control technique. One possible RNAi target is the cuticle protein, which is important in insect molting and development. As an example, here we evaluate the possibility of designing double‐stranded RNA (RNA) that is effective for silencing the cuticle protein 19 gene (CP19) in aphids but is harmless to non‐target predator insects. ...

Single‐metal tests were repeated to evaluate the reproducibility of the methods and year‐to‐year variability. Metals were strong ...

Usually, mealworms are reared in a close environment in constant contact with their feed, called substrate. Mostly of the substrates employed for mealworms rearing, used alone or as an ingredient in a feed mix, contain gluten. Therefore, the aim of this work was to evaluate if gluten could be vehiculate by ...

Acute (96‐h) toxicities of 5 systemic insecticides (chlorantraniliprole, cyantraniliprole, flupyradifurone, flubendiamide, and sulfoxaflor) were tested on larval Chironomus dilutus and compared with the neonicotinoid imidacloprid. Three insecticides were less acutely toxic than imidacloprid (2.5–25 times lower). However, chlorantraniliprole and cyantraniliprole were 1.5 to 1.8 times more toxic to ...

One way to improve the efficiency of such methods is through self‐limiting, female‐eliminating approaches that can alter an insect populations' sex ratio toward males. In this microreview, we summarize recent advances in synthetic sex ratio d ...

Abstract:
... Insect metamorphosis is regulated by two main hormones: ecdysone (20E), which promotes molting, and juvenile hormone (JH), which inhibits adult morphogenesis. The transduction mechanisms for the respective hormonal signals include the transcription factors Krüppel homolog 1 (Kr‐h1) and E93, which are JH‐ and 20E‐dependent, respectively. Kr‐h1 is the main effector of the antimetamorphic action of J ...

In insects, more than 50 neuropeptide genes can be present in a single species, and thus neuropeptidergic systems are attractive targets for the development of environmentally friendly pesticides. Such approaches require not only knowledge of the neuropeptidomes of pests, but also ...

Abstract:
... Insects are considered a promising alternative protein source for food and feed, but contain significant amounts of chitin, often undesirable due to indigestibility, disagreeable texture and negative effect on nutrients intake. Fractionation strategies are thus increasingly being applied to isolate and valorize chitin separately. The analysis of chitin generally requires an intensive pretreatment ...

Abstract:
... The present study focuses on trade‐offs between the development rates and their life‐history traits of feeding larvae. Indeed, quick growth is considered to be vital for necrophagous insects such as larvae because they are part of a rapidly changing ecosystem and at the mercy of many predators. However, excessively quick growth can have a negative effect on other life‐history traits (e.g. survivor ...
