In order to evaluate insecticidal potential of some botanical extracts, a factorial experiment of complete randomized design with three replications on Callosobruchus maculatus was adopted for a pilot experiment in the laboratory. Plant extracts were prepared from 22 plants with three solvents (Methanol, Acetone and N-Hexane) with 30% concentration. Experiments were carried out at 25˚C and 70...
Understanding the responses of seeds to detriment interaction external factors is one challenges research, especially with little explored species such as Sonchus oleraceus L. Thus, objective was investigate effect cultivation system, storage time and temperature on physiological potential Seeds were used two systems (organic conventional) in three times (0, 90 180 days) submitted at temperatur...
Concerns about a global decline in pollinators have called for more knowledge the factors influencing wild pollinator abundance and diversity agroecosystems. Agricultural intensification has been identified as main cause of this “global crisis”, particularly due to reductions natural areas holding critical floral nesting resources.
