Circadian rhythms in insect disease vectors [PDF]
Memórias do Instituto Oswaldo Cruz, 2013 Organisms from bacteria to humans have evolved under predictable daily environmental cycles owing to the Earth's rotation. This strong selection pressure has generated endogenous circadian clocks that regulate many aspects of behaviour, physiology and metabolism, anticipating and synchronising internal time-keeping to changes in the cyclical ...

Gene copy number and function of the APL1 immune factor changed during Anopheles evolution
Parasites & Vectors, 2020 Background The recent reference genome assembly and annotation of the Asian malaria vector Anopheles stephensi detected only one gene encoding the leucine-rich repeat immune factor APL1, while in the Anopheles gambiae and sibling Anopheles coluzzii, APL1

Learning and Memory in Disease Vector Insects [PDF]
Trends in Parasitology, 2016 Learning and memory plays an important role in host preference and parasite transmission by disease vector insects. Historically there has been a dearth of standardized protocols that permit testing their learning abilities, thus limiting discussion on the potential epidemiological consequences of learning and memory to a largely speculative extent ...

Insulated piggyBac vectors for insect transgenesis [PDF]
BMC Biotechnology, 2006 Abstract Background Germ-line transformation of insects is now a widely used method for analyzing gene function and for the development of genetically modified strains suitable for pest control programs. The most widely used transposable element for the germ-line transformation of insects is piggyBac.

Pollen limitation of native plant reproduction in an urban landscape
American Journal of Botany, Volume 109, Issue 12, Page 1969-1980, December 2022., 2022 Abstract Premise Evidence suggests that bees may benefit from moderate levels of human development. However, the effects of human development on pollination and reproduction of bee‐pollinated plants are less‐well understood. Studies have measured natural variation in pollination and plant reproduction as a function of urbanization, but few have ...

Microbial Pre-exposure and Vectorial Competence of Anopheles Mosquitoes
Frontiers in Cellular and Infection Microbiology, 2017 Anopheles female mosquitoes can transmit Plasmodium, the malaria parasite. During their aquatic life, wild Anopheles mosquito larvae are exposed to a huge diversity of microbes present in their breeding sites.

Automating insect monitoring using unsupervised near-infrared sensors [PDF]
arXiv, 2021 Insect monitoring is critical to improve our understanding and ability to preserve and restore biodiversity, sustainably produce crops, and reduce vectors of human and livestock disease. However, conventional monitoring methods of trapping and identification are time consuming and thus expensive.

Immune responsiveness in vector insects [PDF]
Proceedings of the National Academy of Sciences, 1997 Insects have been particularly successful in evolution, and current estimates are that they represent three-quarters of all extant animal species. With the marked exception of the seas, insects occupy nearly all ecological niches on earth and hence are confronted to innumerable potential pathogenic bacteria, viruses, fungi, and protozoan and helminth ...

The Role of Temperature in Shaping Mosquito-Borne Viruses Transmission
Frontiers in Microbiology, 2020 Mosquito-borne diseases having the greatest impact on human health are typically prevalent in the tropical belt of the world. However, these diseases are conquering temperate regions, raising the question of the role of temperature on their dynamics and ...

Impact of temperature on dengue and chikungunya transmission by the mosquito Aedes albopictus
Scientific Reports, 2022 The mosquito Aedes albopictus is an invasive species first detected in Europe in Albania in 1979, and now established in 28 European countries. Temperature is a limiting factor in mosquito activities and in the transmission of associated arboviruses ...
