Perceptions were assessed using a five-point Likert scale (Cronbach's α = 0.76), complemented by data on pesticide practices and Bt cotton adoption potential, collected in 2022. Results revealed substantial perception-practice gaps: while 96% recognized health risks from excessive pesticide use, only 77% used personal protective equipment. Critical knowledge deficits were evident, with only 68.4% understanding stage-specific application requirements and 53.4% aware that insect-resistant varieties reduce pesticide costs. Most farmers (55%) relied on peer consultation rather than extension services for pesticide application decisions. Concerning disposal practices prevailed, with 39.7% burying containers and 30% leaving them in fields. Despite chemical reliance, farmers demonstrated high adoption of nature-based practices, particularly pheromone traps (89.5%) and removal of affected parts (84.6%). Regarding Bt cotton, 86% expressed willingness to adopt at current prices, declining to 52.5% at 50% premium, revealing severe price sensitivity. Findings highlight critical gaps between risk awareness and safety practices. Realizing Bt cotton adoption potential requires intensive extension programming addressing knowledge deficits, improved waste management infrastructure, and financial support for resource-constrained smallholder farmers.</div></div>","PeriodicalId":10785,"journal":{"name":"Crop Protection","volume":"203 ","pages":"Article 107548"},"PeriodicalIF":2.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146072094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to identify alfalfa cultivars with natural resistance to <em>A. craccivora</em> and to elucidate the underlying resistance mechanisms by testing the hypothesis that specific plant nutrients and secondary metabolites are key drivers of aphid resistance. To evaluate the suitability of alfalfa cultivars for cultivation in southern China in terms of their resistance to <em>A. craccivora</em>, life tables were constructed for aphids reared on different cultivars. In addition, the nutrient and secondary metabolite contents of the alfalfa were quantified, and their correlations with aphid life-history parameters were analyzed. The results showed that alfalfa cultivars significantly influenced the life history of <em>A. craccivora</em>, with the Algonquin cultivar exhibiting the strongest negative effects. Integrating life table parameters with chemical profiling revealed that tannins and total phenols are key biomarkers for resistance. Elevated levels of these compounds were strongly associated with a cascade of detrimental effects on <em>A. craccivora</em>, including reduced adult longevity, shortened oviposition periods, and a decreased net reproductive rate, ultimately leading to suppressed population growth. Algonquin was identified as a cultivar with strong natural resistance to <em>A. craccivora</em>, while also elucidating the physiological and biochemical characteristics underlying resistance among alfalfa cultivars.

We then randomly selected five populations of TSSM from this survey originating from different geographic locations and with variable resistance abilities to pyridaben. We tested these populations both for cytochrome P450-based metabolic breakdown of pyridaben and for target-site mutations. Our survey showed that pyridaben resistance is highly common in the field with 32 populations of 37 tested being resistant to a dose of pyridaben which is double the recommended dose for commercial use in the field. Furthermore, we show that resistance in most populations is likely to be metabolic, and we use a P450-inhibitor to successfully re-introduce susceptibility to three of four resistance populations.

In this study, we investigated the independent and interactive effects of five light spectra (blue, purple, green, red, and white) and four photoperiod regimes (LD: 14:10, 10:14, 16:08, and 08:16 h) on the growth, development, and reproductive traits of <em>O. furnacalis</em>. Using controlled laboratory experiments, we quantified key parameters, including larval survival across instars, larval and pupal durations, pupal weight, pupation rate, adult emergence rate, adult survival, and reproductive output. Both spectral quality and photoperiod significantly affected most traits, often interacting to produce spectrum-dependent photoperiodic responses. Short-wavelength light (blue, purple) generally promoted high larval survival and stable development across photoperiods. Green light extended larval and pupal development but enhanced pupal mass and fecundity. Red and white light produced variable effects across traits. These findings suggest that short wavelengths can diminish photoperiod sensitivity, whereas longer wavelengths enhance it.
