It causes 60% weight loss of the pulses, making them inappropriate for planting or human consumption. <em>C. chinensis</em> is commonly controlled with insecticides; however, these insecticides have negative effects on the environment and non-target organisms. Moreover, repeated exposure to the insecticide causes the resistance in the <em>C. chinensis</em>. Initially the lethal concentration of deltamethrin (LC₅₀) was obtained by the probit analysis. Later the study aimed to examine the impact of a sublethal concentration of deltamethrin on various developmental characteristics and repellency behaviour throughout six successive generations of the <em>C. chinensis</em>. For that, two concentration were selected <em>viz</em> sublethal low concentration (1/20^th) and sublethal high concentration (1/5^th) of the LC₅₀ compared to control. Both concentrations significantly reduce the life table parameters like egg count, total hatching, total development duration, total emergence and adult longevity in the first generation but an increasing trend in all the parameters was observed in subsequent generations (progeny). Additionally, the repellency was maximum in 1^st generation but it decreases with the exposure time and successive generations which shows that it was time and generation dependent. The findings indicate that although there are predominantly adverse effects within the generation, exposure to deltamethrin at sublethal levels over the generations can lead to beneficial effects in the offspring, enhancing their ability to withstand insecticides.</p></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"108 ","pages":"Article 102379"},"PeriodicalIF":2.7,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141623009","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}

The study result revealed that <em>Aspergillus</em> spp., <em>Fusarium</em> spp., and <em>Aspergillus flavus</em> were identified at all storage altitudes (1500, 1800, and 2200 m above sea level (m.a.s.l.)), and the level of fungal growth was affected by storage duration and initial moisture content.

Similarly, there was a higher incidence of <em>Aspergillus</em> spp. at the lower altitude; after 8 months of storage, the relative density of <em>Aspergillus</em> spp. was 69% at 1500 m.a.s.l. altitude.

However, aflatoxin contamination poses significant challenges due to strict FDA action levels for dairy and beef cattle feed. This contamination occurs when <em>Aspergillus flavus</em> infects crops under specific environmental conditions or through improper handling during post-harvest processes. Our research aims to document aflatoxin levels during each stage of post-harvest processing, from cleaning to meal formation.

The implications of these findings could be profound for the dairy industry, where low allowable aflatoxin levels impact both economic and animal health outcomes.
