Interseasonal variation of Chrysodeixis includens (Walker, [1858]) (Lepidoptera: Noctuidae) populations in the Brazilian Savanna

Molecular Variability and Genetic Structure of Chrysodeixis includens (Lepidoptera: Noctuidae), an Important Soybean Defoliator in Brazil

This study provides the first genetic characterization of the soybean looper, Chrysodeixis includens (Walker, 1857), an important defoliating pest species of soybean crops in Brazil. Population genetic variability and the genetic structure of C. includens populations were evaluated by using ISSR markers with samples from the major soybean producing regions in Brazil in the growing seasons 2011/...

Evaluation of seven viral isolates as potential biocontrol agents against Pseudoplusia includens (Lepidoptera: Noctuidae) caterpillars.

The caterpillar Pseudoplusia includens (Walker, 1857) (Lepidoptera, Noctuidae), known as soybean looper, is a pest that has recently assumed greater importance in soybean in Brazil. Isolates of nucleopolyhedroviruses (NPVs) of this pest have been identified from cotton in Guatemala and soybean farms in Brazil, providing an interesting perspective of potential use of viral insecticide against th...

Growth of Wild Pseudoplusia Includens (lepidoptera: Noctuidae) Larvae Collected from Bt and Non-bt Cotton

Genetic variation among Mediterranean populations of Sesamia nonagrioides (Lepidoptera: Noctuidae) as revealed by RFLP mtDNA analysis.

Restriction fragment length polymorphism analysis of two segments of mitochondrial DNA (COI and 16S rRNA) was used to examine genetic variation in Sesamia nonagrioides (Lefèbvre) populations from the Mediterranean basin. Four populations were collected from central and southern Greece, and five from northern latitudes: Greece, Italy, France and Spain. No variation was observed in COI, while 16S...

A geometric morphometric study on geographical Iranian populations of the pod borer, Helicoverpa armigera (Lepidoptera: Noctuidae)

تصاویر بال جلو و عقب (به ترتیب دارای 15 و 12 لندمارک) 5 جمعیت جغرافیایی پروانه‌ی کرم غوزه‌ی پنبه، Helicoverpa armigera (Hübner)، از مناطق مختلف شمال و شمال غرب کشور مورد تجزیه و تحلیل چند متغیره قرار گرفت. تعداد 287 تصویر متعلق به بال جلو و 277 تصویر متعلق به بال عقب با استفاده از 26 متغیر ریخت‌سنجی هندسی در بال جلو و 20 کاراکتر در بال عقب با یکدیگر مقایسه شدند. آنالیز فاکتورهای مربوطه نشان داد...
