However, understanding the decomposition process by blowflies in practice presents challenges due to the direct influence of adults and larvae on the process. Environmental factors can either hinder or stimulate colonization by different species, leading to variability across different settings. In this study, we aimed to investigate the variation in the community of adult and immature stages of Calliphoridae blowflies during pig carcass decomposition in an island area of the Amazon rainforest. We identified changes in abundance, richness, and species composition separately for adults and larvae and measured the congruence between larval and adult communities. Our findings revealed that the peak abundance of adults preceded the peak abundance of larvae during carcass decomposition. Eleven species were collected within the first 4 days of decomposition, of which only seven colonized the carcass. Species composition differed between life stages and decomposition phases, with larvae associated with the skeletonization phase and adults with the colliquative phase. The species composition of adults collected from the decomposing carcass corresponded to that of larvae collected 1 day later. This is the first study conducted in an Amazonian island environment in the extreme north of Brazil to document the cadaveric fauna and analyze the congruence between adult and larval communities of blowflies. These insights contribute to forensic entomology understanding and assist forensic professionals, particularly in tropical regions with high rates of unsolved homicides like Brazil.</p>","PeriodicalId":19071,"journal":{"name":"Neotropical Entomology","volume":"54 1","pages":"13"},"PeriodicalIF":1.4,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142818407","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 CO-alone, SO-alone, JB-alone, SH-alone, SO + JB, CO + SH, MI + SH and SO + SH mixtures resulted in reproduction rates similar to those observed with the standard diet, indicating their suitability for C. externa. In contrast, the effects of MI-alone, MI + JB and CO + JB on reproduction were significantly worse than those of the standard diet. In terms of nutritional value, SH was the pollen enriched in protein, CO, MI and SO were protein-poor pollens, and the JB and dipollen mixtures presented intermediate levels.

Evidence suggests the cues that mediate pre-oviposition behaviour in Zabrotes subfasciatus (Boheman) are volatile organic compounds (VOCs) emitted by the seeds and suggests differential abilities in environment sensing between sexes. Here, we tested whether VOCs from different legume species trigger different levels of attraction, whether females and males differ in their ability to respond to VOCs, and whether the seeds promoting different behaviours feature singular VOCs. Finally, we tested females' response to selected VOCs from legume seeds with different levels of attraction. Behavioural assays testing the beetles' response to four Fabaceae species allowing varied levels of fitness (Phaseolus vulgaris, Glycine max, Lens culinaris, and Cicer arietinum) and antenna removal assays confirmed volatiles emitted by the seeds act as chemical cues for females and showed the seeds of the tested legume species trigger different levels of attraction. GC-MS analysis revealed the seeds of two of the species at the extreme of the preference hierarchy feature singular VOCs profiles and abundance. One of the differentially expressed VOCs found in higher quantities in P. vulgaris (ethenylbenzene = styrene) and one in C. arietinum (2-ethyl-1-hexanol) mediate opposing behaviours in Z. subfasciatus females. These results suggest host choice in Z. subfasciatus relies upon at least a two-component kairomone-based system: styrene attracts females to P. vulgaris seeds and 2-ethyl-1-hexanol keeps them from choosing C. arietinum as a substrate for oviposition. The system has evolutionary and agricultural relevance because it may allow for \"niche\" specialisation in seed stores and natural environments and may help develop pest management strategies.</p>","PeriodicalId":19071,"journal":{"name":"Neotropical Entomology","volume":"54 1","pages":"9"},"PeriodicalIF":1.4,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142818474","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}

A longer preadult period, lower preadult survival rate, and lower reproduction were obtained for the pest cohort feeding on treated plants, which resulted in lower population parameters, i.e., intrinsic growth rate, finite growth rate, and net reproduction rate. The population projection results showed the same trend as the population parameters. These results can be attributed to the changes caused by microorganisms in the treated plants. There was no oxidative stress in the treated plants. Instead, the chlorophyll content in these plants increased, and the protein-carbohydrate ratio decreased. Additionally, we assessed the effects of plant-insect-microorganisms interaction on total glutathione levels, glutathione S-transferase, and esterase enzyme activities in S. exigua. Overall results indicate that beneficial microorganisms tested enhance the plant's ability to defend against the pest.

Attempts to control these outbreaks, usually occurring at the end of the soybean cycle and the beginning of the maize cycle, were made by spraying insecticides at the time of soybean desiccation in addition to insecticide seed treatment on maize, but apparently it has been insufficient to provide acceptable control. Therefore, this study was carried out in two consecutive seasons (2016 to 2018) to evaluate different management strategies for the control of D. melacanthus at the end of the soybean cycle and the beginning of the maize cycle, a period of time in which major D. melacanthus outbreaks have been frequently recorded. Late stink bug control (insecticide spray at development stage R7 of soybean) significantly reduced pest populations but left insecticide residue in the soybean grains. Pre-harvest desiccation with and without addition of insecticides (also at R7) also reduced pest populations but negatively impacted soybean yield. Seed treatment on maize numerically reduced the number of stink bugs, without significant difference from maize without seed treatment, but still resulting in higher yield. Thus, we conclude that the best of the here evaluated treatments is the adoption of soybean-IPM (Economic Threshold, ET at levels of two stink bugs/m) during soybean pod development/filling (R3 to R6) to guide insecticide use in addition to maize seed treatment.</p>","PeriodicalId":19071,"journal":{"name":"Neotropical Entomology","volume":"54 1","pages":"5"},"PeriodicalIF":1.4,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142801561","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}

In this study, we analyzed genetic diversity in natural and managed colonies as well as in drone congregations of Scaptotrigona mexicana (Guérin), to assess genetic diversity, patterns of genetic structure and gene flow, and the presence of diploid males. We identified three distinct genetic groups: Northern, Central, and Southern. Although genetic differentiation and limited gene flow among genetic groups were evident, we detected significant gene flow from wild to managed populations, suggesting that natural populations can be an important reservoir of genetic diversity. The highest genetic diversity was found in the Northern group, composed of managed localities. This is likely due to the introduction of new alleles through to colony translocation. Notably, some loci exhibited more than three alleles in localities where all analyzed individuals were from the same colony, indicating possible polyandry in the species.
