Polymorphisms in mitochondrial DNA of european and Africanized honeybees (Apis mellifera) [PDF]
Experientia, 1988 This study demonstrates polymorphisms in both the length and in the restriction enzyme cleavage sites of honeybee mitochondrial DNA (mtDNA). The levels of variation are typical of those found in other metazoan species. These polymorphisms are potentially useful for the identification of Africanized bees in the western hemisphere and for study of ...

Honey bee attractants and pollination in sweet orange, Citrus sinensis (L.) Osbeck, var. Pera-Rio
Journal of Venomous Animals and Toxins including Tropical Diseases, 2004 This experiment studied the frequency and behavior of insects on sweet orange flowers, Citrus sinensis (L.) Osbeck, their effect on fruit production (quantity and quality), nectar and pollen collection, and the effectiveness of different attractants ...

Orchard netting impacts on biodiversity leading to cascading effects at the ecosystem level
Biological Reviews, Volume 101, Issue 5, Page 2448-2466, October 2026.ABSTRACT Agriculture must ensure food production without further compromising the ecosystem functions upon which it depends. Agricultural practices should therefore avoid harming farmland biodiversity, especially of taxa that supply the key ecosystem services (e.g.

Physicochemical characteristics of organic honey samples of africanized honeybees from Paraná River islands. [PDF]
, 2011 This research was carried out to evaluate the physicochemical composition of organic honey in Paraná River islands, in Porto Brasílio, State of Paraná. Honey was harvested directly from super of the colonies in three apiaries spread in the Floresta and ...

The Future of Native Bees in Australia Under Environmental and Anthropogenic Change
Ecology and Evolution, Volume 16, Issue 10, October 2026.Bees are considered one of the most important and abundant pollinators across the globe, yet they are under threat from anthropogenic activities such as land‐clearing, urbanisation, agricultural activities, pesticide use, non‐native flora and fauna introductions, disruption of natural fire regimes, pollution and climate change, among others.

Control agents on the quality of Africanized honeybee queens
Semina: Ciências Agrárias, 2020 The objective of this study was to evaluate the effect of the entomopathogenic fungus Beauveria bassiana, used in large field crops, and of the pomegranate Punica granatum aqueous extract, with insecticidal potential for insect control, on the quality of Africanized Apis mellifera queens.

Lesions caused by Africanized honeybee stings in three cattle in Brazil [PDF]
Journal of Venomous Animals and Toxins including Tropical Diseases, 2013 We report three cases of stings by Africanized bees in cattle in the state of Rio de Janeiro, Brazil. Erythema, subcutaneous edema, necrosis accompanied by skin detachment, and subsequent skin regeneration were observed, especially on the head and dewlap.

Sociobiology, 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 ...

Polyphenism Through RNA Chemical Modifications
Molecular Ecology, Volume 35, Issue 19, October 2026.ABSTRACT Polyphenism, the capacity of a single genotype to produce discrete phenotypes in response to environmental cues, has long served as a model for understanding developmental plasticity. While classical studies have highlighted hormonal signalling and transcription‐factor‐driven gene regulatory networks that mediate these environmentally induced ...

African bush elephants respond to a honeybee alarm pheromone blend [PDF]
Current Biology, 2018 We here report the responses of African bush elephants (Loxodonta africana) to a crude approximation of the honeybee alarm pheromone blend. We show that the elephants had an avoidance response to the semiochemical blend. The use of honeybee alarm pheromones to manage elephant movements in a non-invasive manner, using natural cues to which elephants may
