Bottom-up plant availability, top-down natural enemy pressure, or limits in host discrimination may shape host plant selection. We studied host plant selection of the grassland caterpillar <i>Gynaephora alpherakii</i> on the Qinghai-Tibetan Plateau through field surveys, laboratory choice experiments, and controlled feeding trials to determine the relative importance of these mechanisms. In the field, caterpillars fed predominantly on sedges (Cyperaceae) relative to grasses (Poaceae), but host plant selection closely followed local plant availability, indicating that realized feeding patterns were mainly driven by local resource abundance rather than intrinsic preference. Neither parasitism rate nor parasitism risk was associated with host plant feeding distributions, indicating no detectable effect of population-level parasitism pressure on caterpillar feeding distributions under the field conditions investigated. The laboratory choice experiment revealed that caterpillars recognized and avoided the toxic non-host <i>Stellera chamaejasme</i>, whereas preference between the common host plants, the grass <i>Deschampsia cespitosa</i> and the sedge <i>Kobresia capillifolia</i>, was weak and differed only among the largest caterpillars, suggesting that host plant choice may change during development. Feeding trials further showed that grasses with higher nitrogen and phosphorus concentrations supported greater survival and faster growth relative to sedges, despite being consumed less frequently in the field. These findings indicate that caterpillars show little evidence of strong intrinsic preference among common host plants and that realized host plant selection was more closely associated with bottom-up plant availability than with population-level measures of top-down parasitoid pressure in the studied alpine meadow system. The potential performance benefits of feeding on higher-quality host plants might be moderated under natural conditions by having access to multiple food resources throughout development.</p>\u0000 </div>","PeriodicalId":11741,"journal":{"name":"Entomologia Experimentalis et Applicata","volume":"174 11","pages":"1334-1344"},"PeriodicalIF":1.9,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149177417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These behaviours may arise from either adaptive or non-adaptive processes. One hypothesis suggests that SSB can occur when courtship costs are low or when missing a mating opportunity is costly leading to a reduced behavioural threshold for courtship—a ‘broad mating filter’, as predicted by threshold acceptance theory. We investigated SSB in males of the parasitoid wasp <i>Venturia canescens</i> (Gravenhorst, 1829, Hymenoptera: Ichneumonidae), a species where encounters between partners are infrequent, females are monandrous and male courtship is not energetically costly at least in terms of longevity. We hypothesised that males exhibit a broad mating filter, accepting conspecifics for courtship regardless of sex. First, behavioural assays assessed whether SSB correlated with higher reproductive success. 18% of males displayed SSB, and these behaviours had no detectable effect on either courting or mating success. Thus, males expressing SSB did not experience any reproductive advantage. Since literature shows that cuticular compounds can be cues for sex recognition, we compared, in a second experiment, cuticular hydrocarbon (CHC) profiles between sexes. Our chemical analyses suppose quantitative CHC differences between males and females, indicating that males would ignore those potential cues for sex recognition when expressing SSB. Our findings support the hypothesis of a broad mating filter in <i>V. canescens</i> males. In this species, where conspecific encounters are rare, SSB appears to arise from reduced discrimination rather than adaptive benefits.</p>\u0000 </div>","PeriodicalId":11741,"journal":{"name":"Entomologia Experimentalis et Applicata","volume":"174 11","pages":"1408-1416"},"PeriodicalIF":1.9,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149177343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We outline the evolutionary origins of neuropeptidergic signalling and highlight how recent advances in genomics, transcriptomics, and peptidomics have expanded knowledge of neuropeptide diversity across both model and pest insects. Rather than providing a mere descriptive inventory, the review examines how major neuropeptide families and their G protein-coupled receptors influence behavioural decisions and internal state-dependent responses. We also discuss emerging strategies that target neuropeptide pathways to modify insect behaviour, such as RNA interference, peptidomimetic compounds, and small-molecule receptor modulators, assessing their potential as selective and environmentally friendly alternatives to conventional insecticides. At the same time, we address present limitations, including functional redundancy, variable responses in field conditions, challenges in delivery and stability, and possible non-target effects.

Disentangling Predatory Arthropod Assemblages in Indonesian Croplands","authors":"Akhmad Rizali,&nbsp;Muhammad Arif Firman Syahputra,&nbsp;Moch.

However, the relative impacts of landscape configuration, local management, and underlying abundance biases remain highly debated. To disentangle these drivers, we assessed the species richness and community composition of generalist predators (spiders, carabid beetles, and ants) in two highly contrasting Indonesian farming systems: flooded rice fields and intensive dryland cabbage fields. We sampled ground-active and low-foraging predatory arthropods across 24 sites (12 per crop type) using a standardized combination of pitfall and yellow pan traps. We also evaluated local management intensity and landscape metrics within a 500-m radius. Generalized linear models and multi-model inference revealed that total individual abundance overwhelmingly governed observed species richness across all taxa. This pattern suggests that apparent richness differences were largely driven by variations in local population size, although abundance may also represent an ecological pathway through which habitat quality influences species richness. In contrast, non-metric multidimensional scaling revealed that habitat identity strongly shaped community composition. Spider and ant assemblages diverged significantly between the two crop types: flooded rice fields were dominated by active hunters (e.g., Lycosidae) and moisture-dependent ants (<i>Lophomyrmex</i>), whereas cabbage fields favored disturbance-tolerant opportunists (e.g., <i>Monomorium</i>). Conversely, carabid beetles showed broadly overlapping community structures across both systems, suggesting weak habitat specificity in this highly mobile group. In conclusion, within the sampled predator strata, perceived richness variation was largely driven by abundance, whereas community structure was strongly linked to local habitat identity. Therefore, agronomic conservation strategies should prioritize enhancing the baseline carrying capacity of dominant predators to strengthen assemblages relevant to biological control, rather than assuming that ecosystem services can be secured solely by maximizing species richness or altering landscape structure.</p>\u0000 </div>","PeriodicalId":11741,"journal":{"name":"Entomologia Experimentalis et Applicata","volume":"174 11","pages":"1356-1368"},"PeriodicalIF":1.9,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149177232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Egg cannibalism provided immediate benefits to first instars by expediting molting; however, it slowed the development of later instars. The non-cannibal later instars fed on aphid, <i>Aphis craccivora</i> (Koch) developed faster with greater bodyweights and immature survival (%) than the cannibals. Both egg cannibalism and aphid predation, however, did not affect adult emergence (%) with female-biased sex ratio. For reproduction, three subsets were designed, viz. (i) Non-cannibal adults who never ate eggs, (ii) Cannibal-adults who ate eggs only during immature stages and after emergence fed on aphids, and (iii) Cannibal-adults who never ate aphids. Non-cannibal females of both species had shorter pre- and post-oviposition periods with longer oviposition period, fecundity, percent egg-viability and adult longevity. We report that cannibal females of <i>M. sexmaculatus</i> and <i>H. variegata,</i> who never ate aphids, laid 21.90 ± 4.8 and 13.4 ± 9.30 eggs, respectively, with viability of 32.30% ± 5.07% and 29.27% ± 10.33%, respectively, indicating that females cannibalizing eggs throughout their entire life span can ensure their progeny's subsistence during aphid scarcity. We conclude that egg cannibalism provides instant energy to foraging ladybirds, facilitating their survival and supplementing the development of neonates.

Application of MeSA to coffee plants, regardless of dose, increased host preference by <i>P. citri</i> nymphs compared with untreated plants, whereas treatment with MeJA, either alone or in combination with MeSA, particularly at higher doses, reduced herbivore preference. Treatment with any of the elicitors, irrespective of dose, delayed <i>P. citri</i> development, particularly on plants treated with MeJA alone.

Herein, the cuticular protein gene MpCP19a of M. persicae was cloned and identified. Sequence analysis revealed that it contains a typical ChtBD4 functional domain characteristic of the CPR protein family.

The expression level of MpCP19a in aphids was significantly up-regulated upon UV-B exposure. When MpCP19a was knocked down by RNAi, the survival rate of M. persicae decreased under UV-B exposure, accompanied by a significant reduction in body size and the formation of brown pigmentation on the body surface. In contrast, under normal conditions (without UV‑B stress), knockdown of MpCP19a did not significantly affect survival rate, body size, or pigmentation compared with the dsGFP control and negative control group.
