Negative ecological impacts of honeybees begin at densities below recommended levels for crop pollination

open access: yesJournal of Applied Ecology, EarlyView.
The ecological consequences of high‐density honeybee management are significant, calling for a re‐evaluation of pollination strategies in agricultural landscapes. Setting evidence‐based hive density guidelines is critical to balancing agricultural productivity with the conservation of native pollinator communities and the maintenance of healthy ...

Stress in dipteran insects mass‐reared for sterile insect technique applications

open access: yesInsect Science, EarlyView.
The connections between biotic and abiotic stress affecting mass‐reared dipteran insects and the associated stress and immunological responses. Numbers indicate the order in which the topics are discussed in this review. Abstract Stress may be viewed as the disturbance of homeostasis of an organism.

Analysis of Mortality in Africanized Honey Bee Colonies with High Levels of Infestation by Varroa destructor

open access: yesSociobiology, 2014
The mite Varroa destructor (Anderson & Treuman 2000) is one of the world’s most important plagues of apiculture. In Brazil this mite does not encounter good conditions for parasitism because weather conditions are not ideal for its maintenance, and some ...

Ecophysiology of an Avian Invader: Body Condition and Metabolic Rate Adjustments to Ambient Temperature

open access: yesIntegrative Zoology, EarlyView.
This study examines the ecophysiological responses of common waxbills to temperature variation in Portugal. We measured body condition and basal metabolic rate (BMR) during summer and winter across two regions in Portugal. Body condition was negatively correlated with temperature, while the relationship between BMR and temperature varied seasonally. In

Microbial flora in organic honey samples of africanized honeybees from Parana river islands

open access: yes, 2011
The purpose of this study was to verify and compare the main contamination sources and the hygienic/sanitary conditions of organic honey samples of Apis mellifera from Parana River islands. Thirty-three (33) samples were analyzed between January 2005 and

Electrophysiologic and behavioral responses mediated by volatiles involved in the repellency of Apis mellifera (Lepeletier) (Hymenoptera: Apidae)

open access: yesEntomoBrasilis, 2020
Repellent volatiles to insects might be an important tool for management of bees in areas which the presence of these organisms is not required. This study aimed to evaluate the electroantennal and behavioral responses of Africanized honeybees (workers),
