Recent studies have shown that height influences the abundance and richness of insects. Information on these factors is scarce for species of Chrysopidae at different heights in agricultural and forest environments. This study aimed to evaluate the influence of height on the abundance and richness of green lacewings in an anthropically modified environment. Multilure traps baited with putrescine and ammonium acetate were placed in four areas of the \"Luiz de Queiroz\" Campus (Piracicaba, São Paulo State, Brazil) at two heights (2 and 10 m) from April 2019 to March 2020. Species captured in traps hung at 2 and 10 m above the ground surface were studied with the faunistic analysis ANAFAU, using ecological parameters and diversity indices. The similarity between the species was measured using the Morisita-Horn coefficient. Thirteen species of Chrysopidae were captured, and more species and specimens of green lacewings were collected with the traps at 2 m than at 10 m, that is, height influenced the abundance and richness of the lacewing species. Leucochrysa (Nodita) cruentata (Schneider) was predominant in most areas studied. The highest diversity and abundance of green lacewings was observed on Areão farm in trap at 2 m height. However, Ceraeochrysa claveri (Navás) and Ce. everes (Banks) showed a more similar ecological pattern. Multilure traps baited with putrescine and ammonium acetate were effective in sampling green lacewings, mainly at 2 m height.","PeriodicalId":19071,"journal":{"name":"Neotropical Entomology","volume":" ","pages":"1175-1184"},"PeriodicalIF":1.4,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142350759","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}

The use of indiscriminate amounts and persistent pesticides has not only resulted in insect pest resistance challenges but has also harmed non-target organisms and contaminated the environment. We assessed the cost-effectiveness of Spodoptera litura (Fabricius) resistance to chlorantraniliprole (CTPR) as part of insect resistance control programs. S. litura larvae were collected from the fields and treated with chlorantraniliprole for 15 generations. Compared to the unselected population (Unsel-Lab), the chlorantraniliprole-selected population (CTPR-Sel) of S. litura exhibited a resistance level of 98.23 times. The findings demonstrated that the chlorantraniliprole-resistant genotype had lower egg-to-adult survivability, longer egg-to-adult developing times, and lower fecundity than the chlorantraniliprole-susceptible genotype. Compared to the Unsel-Lab population, the CTPR-Sel population of S. litura had a poorer relative fitness (0.44) at LC30 and shorter male/female longevity. Demographic parameters, including net reproductive rate (R0) and intrinsic (rm) and finite rate of increase (λ), were lower in the CTPR-Sel strain than in Unsel-Lab S. litura. These findings demonstrate that chlorantraniliprole resistance in S. litura has fitness costs at the individual and population levels, implying that removing the selecting agent from the environment might result in less resistance and opportunities for susceptibility restoration. As a result, the current work could help to determine effective management strategies to prevent chlorantraniliprole resistance in S. litura.","PeriodicalId":19071,"journal":{"name":"Neotropical Entomology","volume":" ","pages":"1354-1364"},"PeriodicalIF":1.4,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142504678","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}

This study investigated a novel approach to manage FAW by silica nanoparticles (SiNPs) synthesized from eco-friendly leaf extract of Moringa oleifera Lam. (Moringaceae). This green synthesis method offers a sustainable and potentially safer alternative to traditional chemical processes. SiNP formation was confirmed by various techniques: UV-visible spectrophotometer, X-ray spectroscopy with energy-dispersive (EDX), scanning electron microscopy (SEM), and dynamic light scattering (DLS). The effectiveness of SiNPs alone and their combination with three common insecticides (emamectin benzoate, indoxacarb, and chlorpyrifos) were evaluated against third instar larvae of fall armyworm. While SiNPs after 24 h by leaf dipping method recorded limited insecticidal activity (LC50 = 9947.59 mg/L), it significantly enhanced the potency of all three insecticides. Combining SiNPs with emamectin benzoate resulted in the most dramatic increase in effectiveness compared to the insecticide alone with LC50 = 0.295 mg/L and 0.42 mg/L, respectively. This research suggests that moringa extract can be a valuable resource for the green synthesis of nanoparticles potentially useful in pest control. This approach could potentially reduce the amount of insecticide needed for effective pest control, leading to a more sustainable and environmentally friendly agricultural practice.","PeriodicalId":19071,"journal":{"name":"Neotropical Entomology","volume":" ","pages":"1343-1353"},"PeriodicalIF":1.4,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11534884/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142470740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated the resistance levels of Bt and non-Bt soybean cultivars to C. includens and S. frugiperda, and whether the Bt cultivars can differentially affect these pests across larval stages. No-choice bioassays were conducted using Bt (NS6010 IPRO and P97R50 IPRO) and non-Bt soybeans (UFLA 6301 RR, P96R90 RR, and ANsc 80111 RR) at V4-stage in the laboratory with neonate (24 h) and third-instar larvae. Larvae were fed leaf discs in Petri dishes, recording the mortality, leaf consumption, and weight gain after 7 days. There was high mortality of C. includens neonates on the Bt cultivars, but this trend was not observed for older larvae. For S. frugiperda neonates, there was high mortality on the Bt cultivar NS 6010 IPRO and non-Bt cultivar UFLA 6301 RR, but only the former was effective for older larvae. Although the Bt cultivars did not kill the third instars, antinutritional effects were found, such that leaf tissue consumed was not converted to larval weight gain.

Gall phenology and foliar damage were assessed on 10 trees per site. We characterized gall phenology by assessing their size and color, wasps' developmental stages, as well as affected leaf area and gall density on the leaf blade. Additionally, the individuals found in five attraction traps at each site were quantified biweekly to record population fluctuations. The effect of rainfall on wasp frequency and gall density between sampling sites and dates was compared using the chi-square test, while the relationship with rainfall was evaluated using the Kruskal-Wallis test. Only females of the gall wasp and its parasitoid were observed during the study, displaying multivoltine behavior. Six developmental stages of the galls were differentiated, each characterized by distinct coloration. Drier microclimates favored gall size, wasps' development stage frequency, population trend, and foliar damage.

The present investigation uses various extraction mediums to examine the insecticidal efficacy of essential oils (EOs) isolated from Murraya koenigii (L.) leaves. Increase in yield was observed in the EO extracted using NADES-AHD [0.16% (obtained with hydro-distillation)] to 0.30% [obtained with N-1 (glycerol:lactic acid)]. EO obtained with water was found more effective against A. craccivora (LD50 = 0.89 µL/insect) and followed by N-1 (glycerol:lactic acid), and N-3 (choline chloride:citric acid) (LD50 = 1.29-1.38 µL/insect). Similarly, EO isolated by water and N-4 (choline chloride:oxalic acid) was effective against P. lilacinus (LD50 = 2.63-3.06 µL/insect). Additionally, the EO prepared by water substantially reduced glutathione S-transferase (GST) and acetylcholinesterase (AChE) in target pests, suggesting that these enzymes may be the EOs' site of action. NADES-AHD has enhanced the EO yield as compared to the conventional method. The EO obtained with water showed promising toxicity against target pests and target site of action.
