insects,   etc   ; Arachnida; temperature;     Show all 3 Subjects
Abstract:
... Temperature shapes the processes and outcomes of behaviors that occur throughout the progression of insect and arachnid mating interactions and reproduction. Here, we highlight how temperature impacts precopulatory activity levels, competition among rivals, communication with potential mates, and the relative costs and benefits of mating. We review how both the prevailing temperature conditions du ...

Abstract:
... Arrhenotoky, in which females arise from fertilized eggs and males from unfertilized eggs, has evolved multiple times in animals, most prominently in the insect order Hymenoptera. An alternative form of haplodiploidy, in which females are haploid and males diploid—here named enantiotoky—is not known to exist. An illustrated thought experiment shows that if it does evolve, it will be very unstable ...

Abstract:
... Metacommunity organisation in temporary ponds is assembled by spatiotemporally varying processes that are also contingent on the species’ dispersal ability and scale of observation. Aquatic insects are useful models to study the relative contribution of environmental and spatial factors to community assembly in view of the differing dispersal ability existing in the species from this group. We ass ...

Abstract:
... Insect pest management in certified organic production systems presents considerable challenges for growers. The Federal National Organic Program (NOP) guidelines list acceptable tactics, but their effective use requires a considerable knowledgebase in entomology. The range of tactics allowed by the NOP are viewed as limiting by many growers and there are important elements missing from the list s ...

Abstract:
... There are 3559 species of mosquitoes in the world (Harbach 2018) but, so far, only a handful of them have been a focus of olfactory neuroscience and neurobiology research. Here we discuss mosquito olfactory anatomy and function and connect these to mosquito ecology. We highlight the least well-known and thus most interesting aspects of mosquito olfactory systems and discuss promising future direct ...

This study investigates the protective effect of four strains belonging to Bacillus subtilis (Bs168, Bs2500, Bs2504 and Bs2508) on grapevine roots of the sensitive local grapevine cultivar “Helwani” against phylloxera. Fresh roots were immersed in bacterial suspen ...

Abstract:
... Dragonflies and damselflies are a charismatic, medium-sized insect order (~6300 species) with a unique potential to approach comparative research questions. Their taxonomy and many ecological traits for a large fraction of extant species are relatively well understood. However, until now, the lack of a large-scale phylogeny based on high throughput data with the potential to connect both perspecti ...

Abstract:
... Protozoan parasites acquire essential ions, nutrients, and other solutes from their insect and vertebrate hosts by transmembrane uptake. For intracellular stages, these solutes must cross additional membranous barriers. At each step, ion channels and transporters mediate not only this uptake but also the removal of waste products. These transport proteins are best isolated and studied with patch-c ...

Abstract:
... Recent bumble bee declines have prompted the development of novel population monitoring tools, including the use of putatively non-lethal tarsal clipping to obtain genetic material. However, the potential side effects of tarsal clipping have only been tested in the worker caste of a single domesticated species, prompting the need to more broadly test whether tarsal clipping negatively affects samp ...

Abstract:
... The widespread adoption of artificial lighting at night (ALAN) presents a growing threat to biodiversity in general and nocturnally active insects in particular. ALAN may be contributing to widely reported declines in insect populations but supporting evidence is sparse. Recent advances in external lighting technology, particularly the increasing adoption of broad spectrum ‘white’ LEDs, suggest th ...

Abstract:
... Climate warming is predicted to have large effects on insects, yet several data shortfalls, including distributional information, impede effective conservation strategies. Knowledge of species distributions is a critical component for assessing conservation need but is often lacking for endemic or rare taxa, especially invertebrates. One approach to better inform this gap is by using species distr ...

Abstract:
... Insect cytokine growth blocking peptide (GBP) is synthesized as an inactive precursor, termed proGBP, that is normally present in a significant concentration in the hemolymph of non-stressed animals (Hayakawa, 1990, 1991). Under stress conditions, proGBP is instantly processed to active GBP by a serine protease and this is thought to be an important initial step for insects to cope with stress-ind ...

Insect biodiversity reveals much about ecosystem health and function; however, field studies of insect community composition and diversity are often unintentionally biased by the sampling methods deployed in the study area. Pan traps, particularly yellow pan traps, are a common method for passive community assessment across a variety of taxonomic levels. Our study finds that the diversity, richnes ...

Abstract:
... Cowpeas are an inexpensive source of quality protein but their utilisation is limited by long seed cooking time. This is exacerbated by development of the hard-to-cook (HTC) defect, which also adversely affects starch and protein functionality. Gamma-irradiation can eliminate cowpea seed insect infestation and affects seed functional properties, including reducing cooking time. Hence, the potentia ...
