However, the efficacy of <em>Trichogramma</em> parasitoids is adversely affected by insecticides applied in the field to manage these lepidopteran pests. To overcome this problem efficiently, there is an urgent need to incorporate insecticide-resistant <em>Trichogramma</em> strains into integrated pest management (IPM) programs. This study assessed the potential of <em>Trichogramma chilonis</em> Ishii to develop chlorantraniliprole resistance and characterized resistance associated fitness costs and stability. Toxicity bioassays were performed on <em>T. chilonis</em> using a dry film residue method. After 39 selections, a 573.64-fold level of resistance to chlorantraniliprole was developed in the resistant strain of <em>T. chilonis</em> (Chlr-R) when compared with a chlorantraniliprole susceptible strain (Chlr-S). Chlorantraniliprole resistance in Chlr-R resulted in a female biased sex-ratio and significantly increased the total life span and longevity of the adult female when compared to the Chlr-S strain. Based on age-stage, two-sex life table all the demographic parameters of Chlr-R increased significantly. These results indicate that <em>T. chiloni</em>s can be mass reared and selected for chlorantraniliprole resistance under laboratory conditions, is an important step to improve the in field-based effectiveness and integration of these wasps with chemical control.</div></div>","PeriodicalId":10785,"journal":{"name":"Crop Protection","volume":"187 ","pages":"Article 106979"},"PeriodicalIF":2.5,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142432413","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}

However, chia yield and quality are reduced because of weed competition and the lack of registered herbicides. This study evaluated how chia spatial arrangement suppresses weed growth and provided management options for this crop. The performance of chia plants was assessed over three growing seasons in field experiments using a factorial design that considered spatial arrangement (narrow and wide), weed management (control without weeds, soil bank brassica (<em>Brassica rapa</em> L.), and sown brassica), and cover crop (with or without a rye (<em>Secale cereale</em> L.) cover crop during chia fallow). Chia and brassica are not complementary, leading to resource competition (relative yield total around 1) and negative effects on each other. A significant decrease in chia grain yield of 0.9% per unit increase in the percentage of weeds in total biomass was observed. As chia had a competitive advantage over brassica, the grain yield reduction was ameliorated with a narrow spatial arrangement. Narrow spatial arrangement promotes faster canopy closure during the early growth stages, decreasing light penetration and suppressing weed growth. The high extinction coefficient of chia (0.91) and the low critical LAI (3.3) contributed to this light interception behavior. Accordingly, to maximize chia productivity and profitability, a narrow spatial arrangement is an effective management strategy to suppress weeds. This study contributes valuable insights into chia-weed interactions and emphasizes the importance of sustainable crop management practices.</div></div>","PeriodicalId":10785,"journal":{"name":"Crop Protection","volume":"187 ","pages":"Article 106973"},"PeriodicalIF":2.5,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142428175","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}

It also affected reproduction as evidenced by an approximately 50% reduction in oviposition. Moreover, exogenous application of dsRNA in maize leaves resulted in significant feeding deterrence by FAW larvae, which enhanced the frequency of cannibalism.

Furthermore, complex models with a high number of parameters are often difficult to deploy on resource-constrained embedded devices. To address these challenges, this paper proposes a novel tomato leaf disease recognition method based on DGP-SNNet. Initially, to mitigate issues related to imbalanced samples and overfitting, we introduce a two-stage transfer learning technique alongside a partial convolution module (PConv) to decrease data dependency and enhance model stability. Subsequently, we propose a Global Grouped Location Attention (GGLA) mechanism that dynamically adapts to capture fine-grained disease information, thereby addressing the similarities between disease categories. Finally, we employ a joint compression method utilizing Network Slimming and Neuron Selectivity Transfer, which significantly reduces model size with minimal loss in accuracy. Experimental results demonstrate a classification accuracy of 99.55%, with FLOPs of 1011.88 MB and a parameter count of 4.93 MB. Compared to the baseline model, accuracy improved by 2.23%, FLOPs decreased by 63.39%, and the parameter count was reduced by 75.13%. Additionally, we achieved optimal performance through comparative analyses with other classical and state-of-the-art models, generalization experiments, and module effectiveness tests.

Without effective management of this weed, successful adoption of CA in smallholder farming systems is rather unlikely. Therefore, we aimed to develop an integrated strategy for managing &lt;em&gt;C. rotundus&lt;/em&gt; in CA-based crop rotations. This study encompassed a two-year (during 2020–21 and 2021–22) field experimentation at Kanpur, India with a split-plot design with three replications. The treatments included purple nutsedge management practices in main plot and crop rotations in sub-plot under CA platform (no-tilled with added crop residues).
