Abstract Effects of climate warming on tree growth and physiology may be driven by direct thermal effects and/or changes in soil moisture. Dioecious species usually show sexual spatial segregation along abiotic gradients; however, few studies have assessed the sex-specific responses to dioecious trees. We investigated growth, photosynthesis, nonstructural carbohydrate (NSC), water-use efficiency whole-plant hydraulic conductance (KP) Populus cathayana Rehd. under +4 °C elevated temperature...

Dioecious woody species often exhibit male-biased sex ratios under drought habitat, which may result in vulnerability drying soils. However, whether biased are associated with sex-specific responses growth and defence against insect herbivory stress conditions is unknown. We investigated the sexual terms of Populus yunnanensis Dode response to two water treatments (40% 100% field capacity). Drought reduced plant (e.g., height increment, gas exchange, photosynthetic nitrogen use efficiency,...

The Baluchistan melon fly (Myiopardalis pardalina), a highly invasive tephritid pest, poses critical threat to global cucurbit production, with crop losses exceeding 90% during outbreaks. This review synthesises current research on the pest’s biology, ecology, and management, focusing its severe economic repercussions for key crops—including melon, watermelon, cucumber—across Africa, Asia, Europe. Characterised by life cycle comprising eggs, larvae, pupae, adults, M. pardalina exhibits...

Phauda flammans Walker is a notorious defoliating pest of Ficus spp. in Southeast Asian. Sex pheromones have been identified as an effective method biological control. However, little known about the sex pheromone communication P. due to lack knowledge regarding diel rhythms sexual behavior and field tests using attractants.Adults eclosed from 6:00 16:00 h with peak at 11:00-12:00 mated 9:00 19:00 14:00-15:00 h. The attraction virgin males females suggested utilization pheromones. We...

The Indian meal moth, Plodia interpunctella, poses a significant threat to global agricultural products. Although pheromone-based technologies show promise for P. interpunctella management, limitations like single-sex targeting necessitate exploring complementary strategies. Vegetable-based oils represent potential alternative, but their efficacy, sex-specificity, and interaction with sex pheromones remain unclear. To answer these questions, we first examined attraction of female male adults...

Abstract The antennal sensilla of female Quadrastichus mendeli Kim &amp; La Salle (Hymenoptera: Eulophidae: Tetrastichinae) were observed with scanning and transmission electron microscopy in this study. antenna Q. was geniculate, the flagellum composed seven subsegments. Six distinct types sensory receptors observed, including basiconic capitate peg, böhm, chaetica, campaniformia, placodea trichodea. Sensilla pegs found on flagellomeres, Böhm basal part scape pedicel. Two morphological...

The blue gum chalcid, Leptocybe invasa Fisher & La Salle (Hymenoptera: Eulophidae: Tetrastichinae) is a global pest in Eucalyptus plantations. Diverse modes of reproduction (thelytokous and sexual reproduction) are one the advantages for rapid colonization outbreak this species. Understanding reproductive strategies advantageous us to explore invasive mechanisms. Importantly, how identify both sexes species field crucial issue before we their strategies.

Abstract Male animals usually raise their sperm allocation after detecting competition risk. To date, only a few studies have investigated the cues used by males to sense and respond rivals. Yet, it is still largely unknown whether single or combined they can increase lifetime spermatozoal investment perception of rival cue(s). Here we postulate that ejaculation production from rivals, but such response quickly diminishes are removed. We exposed newly emerged virgin focal moth Ephestia...

Socio-sexual environment can have critical impacts on reproduction and survival of animals. Consequently, they need to prepare themselves by allocating more resources competitive traits that give them advantages in the particular social setting been perceiving. Evidence shows a male usually raises his investment sperm after he detects current or future increase competition because relative numbers determine paternity share. This leads wide use testis size as an index level, yet does not...

In recent years, most studies on the gut microbiome have primarily focused feces samples, leaving microbial communities in intestinal mucosa relatively unexplored. To address this gap, our study employed shotgun metagenomics to analyze compositions normal rectal and matched from 20 patients with colonic polyps. Our findings revealed a pronounced distinction of between these two sample sets. Compared feces, mucosal contains fewer genera, Burkholderia being discriminating genus mucosa,...

Phauda flammans Walker (Lepidoptera, Zygaenidae) is one of the notorious defoliators on Ficus spp. trees. In order to avoid environmental pollution, potential biological control agents for P. need be investigated instead chemical control. Four species insect parasitoids were identified from flammans, including three hymenopteran (i.e., Gotra octocinctus, Apanteles sp. and Eurytoma verticillata) dipteran Exorista yunnanica). Parasitoid ratios G. sp., Eu. verticillata Ex. yunnanica 7.2%, 4.2%,...

Male animals may adjust their resource allocations for reproduction and other fitness functions in response to cues from rivals. For instance, adult males increase investment sperm a higher paternity share when they perceive competition risk surroundings. In nature, both juveniles adults coexist spatially temporally. Yet, it is not clear how juvenile of different ages respond rivals fine-tune lifetime production ejaculation any insect. Here we used the Mediterranean flour moth, Ephestia...
