“…The concentrations of 50, 100, and 200 mL extract L -1 solvent exceeded 80% of germinated seeds, and the treatment using 300 mL extract L -1 solvent was the one with the best results, reaching 97.5% germination. Our germination values are higher than those of Pino et al (2019), who used extracts in ethyl acetate, hexane, and methanol, achieving germination values lower than 50%. Treatments higher than 100 mL extract L -1 solvent of the hydroalcoholic extract of P. ostreatus do not affect maize germination due to the concentration of ethanol absorbed 2 Slope value ± standard error.…”

“…The results of repellency tests recorded RI values greater than 1, which according to Mazzoneto and Vendramim ( 2003) means no repellent effect on adults of S. zeamais (Table 1). Results do not agree with Pino et al (2019), who assessed extracts of P. ostreatus in ethyl acetate, distilled water, methanol, and hexane at concentrations of 0.5%, 1.0%, 2.0%, and 4.0% against adults of S. zeamais. Specifically, the treatments with ethyl acetate at the concentration of 1.0% presented, according to the criteria of Bustos et al (2017), a very high repellency, while the extract with distilled water showed weak repellency.…”

“…Weight loss began to decrease significantly with the concentrations of 100 and 200 mL extract L -1 solvent, with losses of 9.01 and 6.96 g, being the concentration of 300 mL extract L -1 solvent that reached the most significant difference with the control, registering a weight loss of 3.05 g (Table 2). The results again coincide with the ethyl acetate extract evaluated by Pino et al (2019), but it should be noted that, although both treatments report a weight loss close to 8.0 g, the hydroalcoholic extract is much less toxic to mammals than ethyl acetate (Abubakar et al, 2017), making it a better alternative. Concerning the germination of treated maize grains with the hydroalcoholic extract of P. ostreatus, nonsignificant differences were observed among the treatments.…”

“…Regarding its mode of action, Jotic et al (2021) determined that the lectin Ostreolysin A6(OlyA6) produces pores in the midgut membranes of treated western corn rootworm (Diabrotica virgifera LeConte, 1868; Coleoptera: Chrysomelidae). Pino et al (2019) assessed different solvents and obtained a fumigant effect against Sitophilus zeamais only with ethyl acetate. However, considering the high toxicity of this solvent, research is necessary to find alternative solvents of lesser toxicity capable of extracting many chemical compounds.…”

The maize weevil (Sitophilus zeamais Motschulsky, 1855; Coleoptera, Curculionidae) is one of the most important pests associated with stored grains. It is controlled almost exclusively with synthetic insecticides. Thus, leading to problems such as pollution and resistance development. Hence an alternative is the use of natural compounds such as edible mushrooms derivates. The aim of this research was to assess, under laboratory conditions, the insecticidal and insectistatic effect of a hydroalcoholic extract of Pleurotus ostreatus (Jacq.) P. Kumm. 1871 against adults of S. zeamais. The parameters assessed were contact and fumigant toxicity, repellency, and antifeedant effect. The highest contact toxicity (57.5% mortality) was achieved with 30 mL extract L -1 solvent. No treatment showed repellent effect; the repellency index (RI) values were higher than 1, and the antifeeding activity < 30%. The fumigant effect showed a maximum of 30% mortality with the highest concentration (300 μL L -1 air). The hydroalcoholic extract of P. ostreatus exerts contact toxicity and interferes with insect reproduction or oviposition of Sitophilus zeamais.

Excessive use of insecticides has led to resistance of some pathogenic organisms (nematodes, bacteria and fungi), environmental contamination, and the presence of hazardous residues. Therefore, the aim of the present study was to evaluate synthetic metabolites derived from previous studies with edible mushrooms against the soybean weevil Rhyssomatus nigerrimus Fahraeus (Curculonidae) because of the relevance of pest control in an economically important crop. Furthermore, this is one of the first studies where edible fungal molecules are evaluated for the control of these insects. Initially, two in vitro tests (toxic effect and immersion) were evaluated against R. nigerrimus. In these tests, sensitivity and viability were determined in the 2% Tween control in water. For these two tests, the synthetic metabolites pentadecanoic acid (PNA), palmitic acid (PMA), stearic acid (STA), linoleic acid (LNA), β-sitosterol (βT) were evaluated individually as well as in combinations, “the fraction of standards (E1)”. Based on the results obtained, the dip test was selected to evaluate the mixtures of two standards (1. PMA + βT, 2. PMA + PNA, 3. PMA + LNA, 4. PMA + STA, 5. STA + βT, 6. STA + PNA, 7. STA + LNA, 8. PNA + βT, 9. PNA + LNA, 10. LNA + βT), three (1. PNA + βT + LNA, 2. PNA + βT + STA, 3. STA + LNA + PNA and 4. STA + LNA + βT) and four (PNA, βT, LNA and STA). The results showed that the mixture of three standards caused a higher percentage of mortality relative to the control group: l. PNA + βT + LNA and 2. PNA + βT + STA with 54.44 and 48% mortality of R. nigerrimus insects exposed for 15 days. These results show the importance of evaluating mixtures of molecules against R. nigerrimus.

The study aimed to evaluate the insecticidal activity of extracts of edible mushrooms Pleurotus ostreatus and Lentinula edodes against Rhyssomatus nigerrimus. Methanol:water extracts (70:30) of P. ostreatus and L. edodes were made and evaluated in two in vitro tests (exposure and immersion toxic effect) against R. nigerrimus. Subsequently, the toxicity test of the extracts against Artemia salina was evaluated. These extracts were subjected to colorimetric tests and gas chromatography-mass spectrometry. The results showed a mortality effect against R. nigerrimus of 50% for the P. ostreatus 2 extracts at a concentration of 20% in the immersion test. Likewise, in the toxic effect test, 90% mortality was observed after five days of exposure to a concentration of 10%. On the other hand, for the toxicity test, the extract that showed the values with the highest mortality against A. salina was P. ostreatus, starting with 80% mortality at 100μg/mL. The functional groups present in the extracts were saponins, coumarins, and alkaloids. Furthermore, the presence of more than 7 compounds in the mushroom extracts evaluated is reported. This study demonstrates the insecticidal activity of P. ostreatus and L. edodes fungal extracts and indicates the importance of using different in vitro tests to elucidate the mechanism of action for future studies.
