Economic threshold levels for the velvetbean caterpillar on soybeans in Brazil: the social and the private perspectives

open access: yesMemorias do Instituto Oswaldo Cruz, 1987
Pest Control is treated as a economic problem. The social and the private perspectives differ due to the consideration of the environmental and social impacts as well as technical aspects such as resistance, resurgence and secondary pests. A mathematical

Can disease resistance evolve independently at different ages? Genetic variation in age‐dependent resistance to disease in three wild plant species

open access: yesJournal of Ecology, Volume 110, Issue 9, Page 2046-2061, September 2022., 2022
Older plants are typically more resistant to infectious disease than younger plants, but little is known about the structure of age‐dependent resistance in natural populations. We show that there is little genetic correlation between resistance at different ages in three species of wild plants infected by anther‐smut fungi.

Effects of intraguild interactions on Anticarsia gemmatalis and Chrysodeixis includens larval fitness and behavior in soybean

open access: yesPest Management Science, Volume 77, Issue 6, Page 2939-2947, June 2021., 2021
Anticarsia gemmatalis has a competitive advantage over Chrysodeixis includens. Our findings provide significant information regarding lepidopteran development and behavior, contributing to the development of integrated pest management and resistance management strategies Abstract BACKGROUND Crop pest management requires an understanding of the complex ...

A Ground Beetle, Calleida decora (Fabricius) (Insecta: Coleoptera: Carabidae)

open access: yesEDIS, 2005
Calleida decora (Fabricius) is a small arboreal ground beetle, predaceous both as larva and adult. Common on various cultivated crops, it is apparently the only carabid to complete its larval development on Florida soybean foliage (Neal 1974).

Characterization of a Chrysodeixis includens nucleopolyhedrovirus Isolate from Brazilian Cerrado and Assessment of its Co-Infection with Anticarsia gemmatalis multiple nucleopolyhedrovirus [PDF]

open access: yesBrazilian Archives of Biology and Technology, 2019
Chrysodeixis includens has become the major Lepidopteran pest of soybean crops, especially in the Brazilian Cerrado (savanna) region. A native isolate of Chrysodeixis includens nucleopolyhedrovirus (ChinNPV) from this region, Buritis, MG, was assessed ...

Identification and recombinant expression of an antimicrobial peptide (cecropin B-like) from soybean pest Anticarsia gemmatalis [PDF]

open access: yesJournal of Venomous Animals and Toxins including Tropical Diseases, 2021
Background Insects can be found in numerous diverse environments, being exposed to pathogenic organisms like fungi and bacteria. Once these pathogens cross insect physical barriers, the innate immune system operates through cellular and humoral responses.

Survival and development of Spodoptera eridania, Spodoptera cosmioides and Spodoptera albula (Lepidoptera: Noctuidae) on genetically‐modified soybean expressing Cry1Ac and Cry1F proteins

open access: yesPest Management Science, Volume 76, Issue 12, Page 4029-4035, December 2020., 2020
We present data from the first studies that evaluate the survival and development of Spodoptera species on Bt soybeans expressing both Cry1Ac and Cry1F proteins (event DAS‐444Ø6‐6 × DAS‐81419‐2). Abstract BACKGROUND Spodoptera eridania (Stoll), S. cosmioides (Walker) and S.

Hydrocarbon pheromone biosynthesis of female velvetbean caterpillar moth, Anticarsia gemmatalis [PDF]

open access: yes, 2003
Two hydrocarbon pheromone components, (Z,Z,Z)-3,6,9-20:3 HC and (Z,Z,Z)-3,6,9-21:3 HC, of adult female velvetbean caterpillar moths, Anticarsia gemmatalis, were detected both during scotophase and photophase, but pheromone titers during scotophase were ...

Trypsin-like activity of membrane-bound midgut proteases from Anticarsia gemmatalis (Lepidoptera: Noctuidae)

open access: yesEuropean Journal of Entomology, 2005
Membrane-bound proteases from preparations of the midgut of 5th instar velvetbean caterpillars, Anticarsia gemmatalis (Hübner) were obtained by resuspension of the pellet obtained after 100,000 g centrifugation.
