Environmental and genetic control of insect abundance and herbivory along a forest elevational gradient
(Springer, 2011-04)
Environmental conditions and plant genotype may influence insect herbivory along elevational gradients. Plant damage would decrease with elevation as temperature declines to suboptimal levels for insects. However, host ...
Divergência genética de genótipos de feijoeiro a infestação de Zabrotes subfasciatus (Bohemann) (Coleoptera: Bruchidae)
(Universidade Estadual de Londrina (UEL), 2013-01-01)
The aim of this work was to evaluate the genetics divergence of bean genotypes in relation to the oviposition, feeding and development of Zabrotes subfasciatus, determining the degrees of resistance to the weevil. The ...
Antixenosis to Chrysodeixis includens (Lepidoptera: Noctuidae) among soybean genotypes
(Inst Agronomico, 2018-01-01)
The soybean looper Chrysodeixis includens is one of the main defoliating pests of soybean cultures in Brazil. This work aimed to evaluate the effect of offering different soybean genotypes to this insect to verify the ...
Climate change: Resetting plant-insect interactions
(American Society of Plant Biologist, 2012-12)
Elevated CO 2 and temperature are altering the interactions between plants and insects with important implications for food security and natural ecosystems. Ecologically, the acceleration of plant phenology by warming is ...
