Abstract BACKGROUND Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) is one of the major pests maize and in same feeding guild as noctuid Helicoverpa zea (Boddie) armigera (Hübner), recently reported South North America. The intraguild interactions these species were assessed laboratory field conditions by determining survival larvae interaction scenarios with non‐ Bt silks ears. Moreover, a video tracking system was utilized to evaluate behavioral parameters during larval or...

Abstract This study aimed to evaluate the effect of keeping three couples in same cage, and size adults emerged from small, medium-sized large pupae (278.67 mg; 333.20 mg 381.58 mg, respectively), on reproductive potential S. eridania (Stoll, 1782) adults, under controlled conditions (25 ± 1 °C, 70% RH 14 hour photophase). We evaluated survival, number copulations, fecundity fertility adult females. The survival females these different pupal sizes did not differ statistically, but males was...

The fall armyworm, Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae), a native to the Americas and recently reported in Africa, Germany, Netherlands India, is significant pest of many crop species. Although widespread important pest, information on its biology development are incomplete require detailed study. In this study, biotic potential reproductive parameters S. were evaluated under controlled conditions (25±1 °C, 70±10% RH 14 hour...

The western bean cutworm (WBC), Striacosta albicosta (Lepidoptera: Noctuidae), can be a severe pest of transgenic corn in the Plains and Great Lakes regions North America, including on hybrids expressing Bacillus thuringiensis (Bt) Cry1F toxin. level geographic distribution resistance are not completely known. Neonate S. from 10 locations between Nebraska New York state were subjected to dose-response trypsin-activated native toxin overlay bioassays. In 2017, mean estimated lethal...

Aerial application of pyrethroids, such as bifenthrin, been major practice adopted to manage this pest. Reports field failure pyrethroids have increased since 2013. populations were collected in 2016 2017 from fields Nebraska, Kansas, Canada screened with bifenthrin active ingredient larval contact dose-response bioassays. Resistance ratios...

Abstract BACKGROUND Crop pest management requires an understanding of the complex interactions among species that potentially impact crop yield. In soybean, velvetbean caterpillar, Anticarsia gemmatalis (Hübner), and soybean looper, Chrysodeixis includens (Walker), are described as key pests, sharing same feeding guild. We assessed intraguild these under laboratory conditions. Fitness cost study was conducted to examine influence competition on insect development. A video tracking system...

Abstract: Mocis latipes (Guenée, 1852) (Lepidoptera: Erebidae) has been recognized as a major owlet caterpillar associated to the herbivory of gramineaceous plants across American continent. During outbreaks, caterpillars are capable completely consuming preferred hosts (grasses) and, when these destroyed, they can move adjacent non-grass and cause similar damage. Meteorological variable such temperature humidity described factors that affect development abundance M. latipes. This paper...

Striacosta albicosta is a crop pest that causes economic damage in the United States and Canada. Only maize dry beans are shown to be suitable hosts, since larval development incomplete on other hosts. The objective of this study was describe developmental parameters immature stages S. feeding beans, non-Bt, Cry1F, Vip3A maize. For Vip3A, mortality 100% after 24 h. Larvae non-Bt had highest survival (70.6%) compared Maize expressing Cry1F higher (31.3%) than (26.0%). significantly faster...

Abstract Feltia subterranea (Fabricius), commonly known as the granulate cutworm, is a common species of owlet moths (Noctuidae) major agricultural importance, widely distributed in Nearctic and Neotropical regions.

The effects of di-n-butylphthalate (DnBP) were investigated with respect to bioaccumulation and whether these occurred over a second generation in the fall armyworm Spodoptera frugiperda (J.E. Smith, 1797). concentrations DnBP males females higher than those first one. However, frequency mortality exposed individuals was approximately 57% less but reduction size weight more pronounced generation.

Exposure of lepidopteran pests to Bacillus thuringiensis (Bt) proteins has been shown affect the behavior larvae, including increased movement and avoidance Bt-expressing plants or diet. Therefore, we hypothesized that western bean cutworm, Striacosta albicosta (Smith) (Lepidoptera: Noctuidae), an important pest maize, could be affected when exposed Bt plants. To test this hypothesis, conducted a series artificial arena on-plant experiments determine S. neonate non-Bt plant tissue. Video...
