“…Tal como lo indican Fenton, Margaritopoulos et al (2010), genotipos de M. persicae con presencia de algún mecanismo de resistencia bajan su potencial reproductivo. Además, existen evidencias de que varias especies de insectos con resistencia a insecticidas reducen su supervivencia y su habilidad reproductiva, además de ser más vulnerables a enemigos naturales (Abbas, Khan & Shad 2015;Castellanos et al, 2019;Guedes, Smagghe, Stark, & Desneux 2016;van Toor et al, 2013). De acuerdo con la prueba de χ 2 , la frecuencia de los tres mecanismos de resistencia fue dependiente de la región de estudio, estando más asociados a la región de O'Higgins para kdr (copias únicas χ 2 = 15,9 y df = 2, p < 0,001 y copias múltiples χ 2 = 29,4 y df = 2, p < 0,001), súper kdr (copias únicas χ 2 = 7,5 y df = 1, p < 0,01 y copias múltiples χ 2 = 12,9 y df = 1, p < 0,001) y MACE (copias únicas χ 2 = 9,9 y df = 2, p < 0,01 y copias múltiples χ 2 = 27,4 y df = 2, p < 0,001).…”

Myzus persicae es considerado la tercera plaga de importancia económica de varios cultivos en Chile. Su variabilidad genética es influenciada por la disponibilidad del hospedante primario. Este insecto ha adquirido resistencia a la mayoría de los insecticidas utilizados para su control. El presente trabajotuvo como objetivo evaluar la diversidad genética y la presencia de mecanismos de resistencia de M. persicae en cultivos como duraznero y pimentón. El estudio se realizó en doce localidades: seis en la región de O'Higgins y seis en la región del Maule en Chile central. Para evaluar la diversidad genética neutral, se utilizaron siete marcadores microsatélites, y la identificación de mecanismos se realizó mediante ensayos de discriminación alélica. La mayor diversidadgenética se presentó en poblaciones del duraznero > 0,80 en promedio. En pimentón y arvenses, esta diversidad fue 0,36 en promedio. La frecuencia de individuos con mecanismos de resistencia fue baja y en forma predominantemente heterocigota en los hospedantes evaluados, lo que sugiere que la forma de reproducción sexual del áfido influye en los niveles de resistencia a insecticida. La presencia de mecanismos de resistencia en M. persicae dependedel hospedante, región geográfica y momento de muestreo en el que son evaluados. Existe suficiente evidencia de que las poblaciones de M. persicae están compuestas por muy pocos grupos genéticos, presentando diferentes dinámicas de resistencia a insecticidas en la misma temporada agrícola.

“…[18][19][20] The application of neonicotinoids, alone or mixed with other insecticides, is the most common practice used against the Neotropical brown stink bug Euschistus heros. [21][22][23][24] This species is the prevailing stink bug pest species of South American soybean-growing fields. 23,25,26 The frequent overuse of neonicotinoid insecticides against this species leads to unintended sublethal effects 27,28 and control failures due to insecticide resistance.…”

BACKGROUND: The use of insecticidal solutions containing sodium chloride (NaCl) has been proposed as a more environmentally friendly alternative to managing stink bug infestations of Neotropical soybean fields. The potential sublethal and undesirable effects of this practice have, however, been overlooked, especially with novel insecticides. Here, we have evaluated experimentally whether the addition of NaCl (0.5% w/v) to imidacloprid-containing solutions could alter insecticide toxicity and modify the reproductive responses of the Neotropical brown stink bug Euschistus heros. RESULTS: Adding NaCl to imidacloprid solutions significantly increased imidacloprid toxicity against E. heros. The exposure to E. heros to sublethal concentrations of imidacloprid affected the insect's mating abilities in a concentration-dependent manner. The addition of NaCl to solutions containing imidacloprid at concentrations as low as 0.126 ∼g a.i. cm −2 (i.e. the equivalent to 3% of field rate recommendation) also impacted the sexual behavior of E. heros, reducing mating duration. NaCl-exposed stink bugs, however, exhibited higher fecundity and fertility rates than those insects that were unexposed to NaCl or those that were exposed to sublethal levels of imidacloprid only. CONCLUSIONS: The addition of low amounts of NaCl resulted in a higher toxicity of imidacloprid. This practice, however, can also lead to undesirable effects as increasing reproductive output of E. heros that can potentially compromise the management of these insect pests.

“…The improper use of chemical pesticides also causes "3R" problems (Resistance, resurgence, and residue). Although at present, resistance to a specific insecticide by weevils has not been reported, many other pests, including Euschistus heros, Laodelphax striatellus, and Frankliniella occidentalis, have reportedly developed resistance to insecticides used to control weevils (Castellanos et al, 2019;Zhang et al, 2019;Wang et al, 2012). The difficulties in controlling C. formicarius by chemical insecticides may be partly because insecticides tend to induce insect resistance.…”

The sweet potato weevil, Cylas formicarius (Fabricius) (Coleoptera: Brentidae), is a destructive insect pest that damages sweet potatoes both in the field and during storage. To identify new environmentally friendly insecticides to control this insect pest, three assays (olfactory test, anti-feeding assay, and toxicity assay) were conducted to evaluate the efficacy and mode of action of 10 botanical insecticides against C. formicarius adults in 2015 and 2016. Of these 10 botanical insecticides, tea saponin, pyrethrins, and veratrine showed significant repellency in olfactory tests. Eight botanical insecticides showed anti-feeding effects in the feeding choice test. Five botanical insecticides had high toxicity. Among them, the lethal concentrations of rotenone were lowest followed by pyrethrins. The lethal time values of rotenone were shortest followed by nicotine. In conclusion, rotenone, pyrethrins, nicotine, and toosendanin have the potential to control C. formicarius adults. Of these, pyrethrins and toosendanin are more environmentally friendly than rotenone and nicotine and were identified as better insecticides to control C. formicarius.
