1. Do dietary stresses affect the immune system of Periplaneta americana (Blattaria: Blattidae)?
Resumo Os estresses podem ser causados por múltiplos fatores bióticos e abióticos e seus efeitos podem afetar tanto a biologia como o sistema imune dos insetos. A barata-americana – Periplaneta americana (Linnaeus, 1758) (Blattaria: Blattidae) – além de ser uma excelente espécie modelo, tem grande importância médica, pois pode atuar como vetor me

2. Bee assemblage in habitats associated with Brassica napus L.
ABSTRACTAssessments in agricultural crops indicate that alterations in the landscape adjacent to the crops can result in reduced productivity due to loss or low abundance of pollinating agents. In the canola crop, production is partially dependent on insect pollination. Therefore, knowledge of the faunal diversity within and near crop fields is key for the m

3. Oviposition behaviour of Phlebotomus argentipes - A laboratory-based study
The breeding habitat of sandflies is a little studied and poorly understood phenomenon. More importantly, oviposition behaviour is a largely neglected aspect of sandfly biology and this knowledge gap further undermines our understanding of the biology of sandflies. Pheromones released by the eggs play an important role in identifying good sites for ovipositi

4. When population and evolutionary genetics met behaviour
In this review, we analyse the impact of a population and evolutionary genetics approach on the study of insect behaviour. Our attention is focused on the model organism Drosophila melanogaster and several other insect species. In particular, we explore the relationship between rhythmic behaviours and the molecular evolution of clock and ion channel genes.

5. Genetic basis of triatomine behavior: lessons from available insect genomes
Triatomines have been important model organisms for behavioural research. Diverse reports about triatomine host search, pheromone communication in the sexual, shelter and alarm contexts, daily cycles of activity, refuge choice and behavioural plasticity have been published in the last two decades. In recent times, a variety of molecular genetics techniques h

6. Circadian rhythms in insect disease vectors
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 environment. I

7. Acoustic communication in insect disease vectors
Acoustic signalling has been extensively studied in insect species, which has led to a better understanding of sexual communication, sexual selection and modes of speciation. The significance of acoustic signals for a blood-sucking insect was first reported in the XIX century by Christopher Johnston, studying the hearing organs of mosquitoes, but has receive

8. History of domestication and spread of Aedes aegypti - A Review
The adaptation of insect vectors of human diseases to breed in human habitats (domestication) is one of the most important phenomena in medical entomology. Considerable data are available on the vector mosquito Aedes aegypti in this regard and here we integrate the available information including genetics, behaviour, morphology, ecology and biogeography of t

9. Acute experimental Trypanosoma cruzi infection: establishing a murine model that utilises non-invasive measurements of disease parameters
Trypanosoma cruzi infection has a large public health impact in Latin American countries. Although the transmission rates via blood transfusions and insect vectors have declined sharply in the past 20 years due to policies of the Southern Cone countries, a large number of people are still at risk for infection. Currently, no accepted experimental model or de

10. Biologia e comportamento de Sitobion avenae (Hemiptera: Aphididae) em quatro cultivares comerciais de trigo (Triticum aestivum L.) / Biology and behavior of Sitobion avenae (Hemiptera: Aphididae) in four commercial varieties of wheat
The use of resistant wheat cultivars to S. avenae is important for the management of culture due to the potential damage of aphid. In Brazil, however, little is known about the resistance of wheat cultivars to S. avenae. The goal of this work was to assess the behaviour and biology of S. avenae in leaves and ears of four commercial wheat cultivars to verify

11. Aplicação de modelos de Markov ocultos na obtenção de taxas de mortalidade das larvas do mosquito da Dengue
In order to prevent the proliferation of Dengue transmitter - scientifically named as Aedes ae- gypti - and therefore decrease human contamination by such insect, many larvaecides have been developed recently. Researchers from Dom Bosco Catholic University evaluate the efectiveness of vegetal-derived substances capable to combat such animal larvae. Death rat

12. Phlebotominae distribution in Janaúba, an area of transmission for visceral leishmaniasis in Brazil
In Brazil, visceral leishmaniasis (VL) is caused by Leishmania chagasi parasites that are transmitted to man through the bites of infected females of Lutzomyia longipalpis sand flies. In order to evaluate transmission risk and to clarify the epidemiology of this tropical disease, studies focused on the vector and favorable environmental conditions are of fun
