Predicting the Potential Distribution of the Endangered Pyrethrum tatsienense in China Using an Optimized Maxent Model Under Climate Change Scenarios. [PDF]

Ecol Evol
This study used the ENMeval function‐optimized MaxEnt to predict the potential suitable area for Pyrethrum tatsienense under climate change scenarios. The lowest month of Mean UV‐B of the highest month (uvb3), elevation (Elev), and the warmest season of precipitation (Bio18) are three identified major factors limiting the distribution of the P ...

Indoor Residual Spraying With Fludora Fusion for Malaria Control in Pyrethroid-Resistant Areas of Gujarat, India: A Community-Randomized Trial. [PDF]

J Trop Med
Background: The development of insecticide resistance in malaria vectors has necessitated a need to evaluate new insecticide molecules with different modes of action. In the present study, Fludora Fusion 562.5 WP‐SB (clothianidin 50% + deltamethrin 6.25% AI/kg) was evaluated for its efficacy and residual action for the control of pyrethroid‐resistant ...
