Abstract: A knowledge of the mechanisms of resistance present in genetic materials should help breeding programs in developing cultivars resistant to insects. The biology of Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae) was studied on leaves of four soybean genotypes with different degrees of resistance to insects. The genotypes evaluated were cultivars IAC 17 and IAC 24, resistant to defoliators and stink bugs, line PI 229358, a source of multiple resistance to insects and used as parent in various lines select… Show more

“…Favetti et al (2015) evaluated the biology of S. eridania in four soybean cultivars and also found differences in the duration of the larval stage, as well as of the pupal stage; however, no differences in pre-oviposition duration, number of eggs, and male and female longevity. Fugi et al (2005) also observed a reduction in the larval stage of A. gemmatalis among soybean cultivars; however, contrary to Favetti et al (2015), the authors reported differences related to female longevity, number of eggs, and egg stage duration. Specht et al (2016) assessed the reproduction potential of S. eridania in soybean and noticed that the number of copulated females was not affected by the size of pupae; however, differences were observed while analyzing egg fertility and adult longevity.…”

“…The incorrect use of insecticides and fungicides on soybean has also been identified as a factor that has contributed to the increase of this insect population, particularly by contributing to a high mortality of biological control agents (Sosa-Gómez et al, 2010). An alternative control measure is the use of plants that are naturally resistant to insects and that can be used for the management of C. includens in soybean (Rose et al, 1989;Piubelli et al, 2005) and dry bean (Morando et al, 2015), as well as of other lepidopteran pests species affecting the soybean crop, such as A. gemmatalis (Fugi et al, 2005), Spodoptera cosmioides Walker, 1858 (Boiça Júnior et al, 2015), and S. eridania Cramer, 1782 (Favetti et al, 2015). This control method allows reducing insect populations to levels that do not cause economic damages to plants, avoiding ecological imbalances and accumulative waste in the environment and foods (HoffmannCampo et al, 2012).…”

“…Cultivar 'IAC-24' also has this resistant 'PI 227687' lineage, constituting an additional source of genetic variability and a broader genetic base for resistance to insects and biotic factors. 'IAC-24' and 'IAC-17' had similar levels of antibiosis-type resistance to A. gemmatalis (Fugi et al, 2005). Phytophagy on the insect-resistant soybean genotype 'PI 229358' also increased the duration of nymph stage of females of the predator Nabis roseipennis Reuter, 1872 (Hemiptera: Nabidae) (Pfannenstiel and Yeargan, 1998).…”

“…The pupal period of C. includens was shorter on the IAC 17 treated with the calcium and magnesium silicate resistance inducer (7.0 days) than with the treatment with sodium silicate (4.50 days) (Table 3). This may be related to the length of the larval stage because each one depends on the earlier one to obtain, synthesize and accumulate the nutritional substances (Fugi et al, 2005). The resistance inducer, sodium silicate, increased the pupal period of C. includens on the BRS Conquista (7.0 days) compared with those on the IAC 100 and IAC 17 (4.5 and 1.5 days), respectively.…”
