Loopers such as Chrysodeixis includens (Walker), Rachiplusia nu (Guenée), and Trichoplusia ni (Hübner) are important defoliators in soybean, sunflower, crucifer crops, respectively, countries of the Americas. The biotic potential these polyphagous species Plusiinae was comparatively examined considering crop rotation succession scenarios which crops cultivated during or after Brazilian winter. All developed reproduced on soybean (BRS 133 Embrapa) forage turnip (Cati AL 1000, Wolf Seeds do...

Helicoverpa armigera is a pest of several crops causing significant economic impact. We evaluated the insect development on different vegetative and reproductive structures cotton, maize, soybean compared to artificial diet. One hundred individuals were per structure (cotton leaves bolls; maize leaves, grains, silk; pods) Centesimal analyses performed quantifiable nutrient contents in diets. The viability immatures (eggs, larvae, pupae) ranged from 30% leaf 74% cotton bolls, while diet, it...

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...
