Forty pitfall traps were placed for each treatment to capture terrestrial arthropofauna in four evaluations. It is concluded that the families that presented the greatest abundance of individuals were Formicidae, Entomobryidae and Poduridae. For the global evaluation, significant differences were found in the predators for the specific richness index, being T3 the one that presented the lowest numbers; while for the Margalef index, the lowest value was T3. For the analysis by evaluations, significant differences were found in the detritivores during the second evaluation for the number of individuals, with T4 being the lowest number. Significant differences were also found in the predators during the first evaluation in the Margalef index, with the lowest value being observed in T4. The trophic guild that allowed the most efficient evaluation of the toxicity were the predators, T1 is the most compatible pesticide with the terrestrial arthropods associated with cocoa cultivation, and the alpha diversity indices showed significant differences between the applied pesticides.","PeriodicalId":54250,"journal":{"name":"Revista De La Sociedad Entomologica Argentina","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43460395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The susceptibility of 2nd and 4th larval instars of C. partellus was assessed against Bacillus thuringiensis var. kurstaki (Bt-k) (Berliner) and Metarhizium anisopliae (Mechnikov) under controlled conditions. The larvae were treated with individual or combined treatments of a single dose rate of B. thuringiensis (Bt: 0.75 µg/g) and three conidial concentrations (1x104, 1x106 and 1x108 conidia/ml) of M. anisopliae. The individual and combined application of both entomopathogens significantly affected the mortality, pupation, adult emergence, mycosis and sporulation of both larval instars of C. partellus. Maximum larval mortality (2nd instar: 94.63% and 4th instar: 91.43%) was recorded in combined applications of M. anisopliae (1x108 conidia/ml) and B. thuringiensis (0.75 µg/g). The same integrated treatment also caused significant declines in pupation (2nd: 0.00% and 4th: 6.66%) and adult emergence (2nd: 0.00% and 4th: 0.00%) of C. partellus as compared to rest of the experimental treatments. Moreover, a significantly higher rate of mycosis and sporulation were recorded in both larval instars (2nd: 88.52% and 143.96 conidia/ml) and (4th: 82.04% and 131.85 conidia/ml), when exposed to lower individual concentration of M. anisopliae (1×104 conidia/ml).
