TL;DR: The results demonstrate that pesticide exposure can substantially impact expression of genes involved in several core physiological pathways in honey bee workers, and there is substantial overlap in responses to pesticides and pollen-containing diets at the transcriptional level, and subsequent analyses demonstrated that pollen-based diets reduce workers' pesticide sensitivity.

TL;DR: The latest developments in regards to the role of microRNA in insect host-pathogen interactions are discussed and some insights into this rapidly developing area of research are provided.

TL;DR: The authors found that 5-HT immunoreactive processes throughout the gut, including on the surface of the oesophagus, crop, proventriculus, and the midgut, as well as in the ventral nerve cord.

TL;DR: The essentiality of linoleic and linolenic acids was consistent with these FAs' tendency to be present at higher levels in collected pollen than in the expected nutrients in bee bodies, demonstrating a well-developed adjustment between pollinator nutritional demands and the nutritional value of food offered by pollinated plants.

TL;DR: It is hypothesised that geraniol possess significant neuromodulatory propensity and may be exploited for therapeutic application in human pathophysiology associated with neuropathy, however, the precise mechanism/s by which Geraniol offers neuroprotection needs to be investigated in appropriate neuronal cell models.

TL;DR: Del (observed under light:dark conditions) time-of-day changes in metabolic detoxification and resistance to insecticide challenge in Anopheles gambiae mosquitoes are characterized and rhythmic susceptibility to insecticides by survivorship and pesticide susceptibility is demonstrated.

TL;DR: Results suggest that AlucOrco is crucial in mediating odorant perception of A. lucorum, especially in perceiving trans-2-hexenal and trans- 2-hexenic butyrate.

TL;DR: The results indicate that AccSOD2 plays an important role in cellular stress responses and anti-oxidative processes and that it may be of critical importance to honeybee survival.

TL;DR: A comparative study of two closely related invasive fruit fly species in China suggests that the difference in thermal plasticity may be responsible for the different distributions of the two species and that Hsp expression may be involved in the regulation of thermal Plasticity.

TL;DR: This extensive meta-analysis supports and extends previous conclusions that solitarious locusts undergo a rapid behavioural gregarization upon receiving appropriate stimulation for a few hours that is mediated by serotonin, at the end of which their behaviour is largely indistinguishable from locUSTs that have been in the gregarious phase their entire lives.

TL;DR: The data suggest that serosa development is at least partially uncoupled from embryo development and that, depending upon the mosquito species, EDR bestows distinct levels of egg viability in these species.

TL;DR: The diapause process modifies greatly the length of embryogenesis in the temperate strain, whereas the maternal photoperiod has a direct influence on egg size and embryogenesis regardless of the strain considered.

TL;DR: Low AA concentrations in nectar relative to pollen suggest a limited role in bee nutrition, with important methodological implications for homing studies that evaluate the effect of substances that may affect imbibition of sugar solution.

TL;DR: The results show that male B. tryoni release ingested lures as part of their pheromone blend and, at least for cuelure, this attracts more females.

TL;DR: In this paper, the authors found that suppression of allatotropin mRNA using RNA interference in females programmed for nondiapause resulted in a cessation of ovarian development akin to diapause.

TL;DR: It is emphasized how studies integrating an array of techniques and disciplines have the potential to provide new understanding of the biology of this micro eco-system.

TL;DR: Results suggest that jmtA LHP RNA expressed in heat inactivated genetically modified P. pastoris cells could be used to control mosquito populations in the marsh, which is consistent with the observed inhibition of egg maturation and larval development.

TL;DR: Dietary introduction of double-stranded RNA of LdRyR significantly reduced the mRNA levels of the target gene in the larvae and adults, respectively, and significantly decreased chlorantraniliprole-induced mortalities.

TL;DR: The physiological limits of cold tolerance measured at individual level in laboratory were safely sufficient for survival of P. chalcographus at any conceivable cold spell that may occur in Central Europe.

TL;DR: The construction and use of a device that uses airflow and pressure to manipulate adult flies and extract high-volume hemolymph samples is described, which is rapid and inexpensive, and does not require cold or CO2 anesthesia at any point in the sampling process, thus avoiding the possible confounding effects of these treatments on the biochemical properties of the Hemolymph sampled.

TL;DR: The results presented here indicate that G. mellonella larvae are capable of altering their immune response following exposure to mild thermal or physical stress to mount a response capable of counteracting microbial infection which reaches a peak 24h after the initiation of the priming event and then declines by 72h.

TL;DR: It is clear that male mosquitoes are able to alter the female's resource allocation priorities towards reproduction by transferring JH III during copulation; reducing the rate of previtellogenic resorption and increasing the amount of stored ovarian lipids.

TL;DR: It is suggested that the axonal projections of this serotonergic cluster in Drosophila larval brain may be part of a brain-gut neural pathway that is functionally analogous to the vertebrate vagus nerve.

TL;DR: It is proposed that the circatidal rhythm of A. asahinai is driven by a clock, the molecular components of which are distinct from that of the circadian clock.

TL;DR: Experimental evidence that NZMF negatively affected the growth and development of SBPH and BPH, with particularly strong effects on reproduction is provided, indicating a negative effect on fertility under NZMF.

TL;DR: This work investigates how simple nutritional interactions between individuals can mediate a range of emergent collective-level phenomena in social arthropods (insects and spiders) and develops a modelling framework integrating concepts of nutritional geometry into individual-based models.

TL;DR: In this paper, the stability of Vip3A proteins to peptidase digestion was studied to see whether the differences found could explain differences in toxicity against these two Spodoptera species.

TL;DR: It is discovered that FKH is the second conserved member of the FoxO family cross-regulating metabolism and innate immunity, which acts in parallel to induce different sets of AMPs, thereby modulating the immune status of metabolic tissues such as the fat body or the gut in response to the oscillating energy status of the organism.

TL;DR: Augmenting the host fly's diet with supplements of putative cryoprotectants enhanced cold tolerance in parasitoids that fed on the flies, thus indicating a tri-trophic effect on parasitoid cold tolerance.

TL;DR: Under the restricted feeding conditions, males ate more nutrients but were less efficient at retaining their body lipids than females, and body lipid content was higher on carbohydrate-rich foods and was positively correlated with starvation resistance.
