| the molecular and immunochemical expression of innexins in the yellow fever mosquito, aedes aegypti: insights into putative life stage- and tissue-specific functions of gap junctions. | gap junctions (gj) mediate direct intercellular communication by forming channels through which certain small molecules and/or ions can pass. connexins, the proteins that form vertebrate gj, are well studied and known to contribute to neuronal, muscular and epithelial physiology. innexins, the gj proteins of insects, have only recently received much investigative attention and many of their physiological roles remain to be determined. here we characterize the molecular expression of six innexin ... | 2015 | 25585357 |
| annotation and expression analysis of cuticular proteins from the tobacco hornworm, manduca sexta. | the insect cuticle is a unique material that covers the exterior of the animal as well as lining the foregut, hindgut, and tracheae. it offers protection from predators and desiccation, defines body shape, and serves as an attachment site for internal organs and muscle. it has demonstrated remarkable variations in hardness, flexibility and elasticity, all the while being light weight, which allows for ease of movement and flight. it is composed primarily of chitin, proteins, catecholamines, and ... | 2015 | 25576653 |
| tsetse gmmsrpn10 has anti-complement activity and is important for successful establishment of trypanosome infections in the fly midgut. | the complement cascade in mammalian blood can damage the alimentary tract of haematophagous arthropods. as such, these animals have evolved their own repertoire of complement-inactivating factors, which are inadvertently exploited by blood-borne pathogens to escape complement lysis. unlike the bloodstream stages, the procyclic (insect) stage of trypanosoma brucei is highly susceptible to complement killing, which is puzzling considering that a tsetse takes a bloodmeal every 2-4 days. in this stu ... | 2015 | 25569180 |
| pyrethroid-resistance and presence of two knockdown resistance (kdr) mutations, f1534c and a novel mutation t1520i, in indian aedes aegypti. | control of aedes aegypti, the mosquito vector of dengue, chikungunya and yellow fever, is a challenging task. pyrethroid insecticides have emerged as a preferred choice for vector control but are threatened by the emergence of resistance. the present study reports a focus of pyrethroid resistance and presence of two kdr mutations--f1534c and a novel mutation t1520i, in ae. aegypti from delhi, india. | 2015 | 25569164 |
| origins of context-dependent gene repression by capicua. | receptor tyrosine kinase (rtk) signaling pathways induce multiple biological responses, often by regulating the expression of downstream genes. the hmg-box protein capicua (cic) is a transcriptional repressor that is downregulated in response to rtk signaling, thereby enabling rtk-dependent induction of cic targets. in both drosophila and mammals, cic is expressed as two isoforms, long (cic-l) and short (cic-s), whose functional significance and mechanism of action are not well understood. here ... | 2015 | 25569482 |

| unique biochemical and molecular biological mechanism of synergistic actions of formamidine compounds on selected pyrethroid and neonicotinoid insecticides on the fourth instar larvae of aedes aegypti (diptera: culicidae). | we recently reported that formamidine pesticides such as amitraz and chlordimeform effectively synergize toxic actions of certain pyrethroid and neonicotinoid insecticides in some insect species on the 4th instar larvae of aedes aegypti. here we studied the biochemical basis of the synergistic actions of the formamidines in amplifying the toxicity of neonicotinoids and pyrethroids such as dinotefuran and thiamethoxam, as well as deltamethrin-fenvalerate type of pyrethroids. we tested the hypothe ... | 2015 | 25987221 |
| synergistic action of octopamine receptor agonists on the activity of selected novel insecticides for control of dengue vector aedes aegypti (diptera: culicidae) mosquito. | studying insecticide resistance in mosquitoes has attracted the attention of many scientists to elucidate the pathways of resistance development and to design novel strategies in order to prevent or minimize the spread and evolution of resistance. here, we tested the synergistic action of piperonyl butoxide (pbo) and two octopamine receptor (or) agonists, amitraz (amz) and chlordimeform (cdm) on selected novel insecticides to increase their lethal action on the fourth instar larvae of aedes aegy ... | 2015 | 25987220 |
| experience- and age-mediated oviposition behaviour in the yellow fever mosquito stegomyia aegypti (=aedes aegypti). | in repeated behaviours such as those of feeding and reproduction, past experiences can inform future behaviour. by altering their behaviour in response to environmental stimuli, insects in highly variable landscapes can tailor their behaviour to their particular environment. in particular, female mosquitoes may benefit from plasticity in their choice of egg-laying site as these sites are often temporally variable and clustered. the opportunity to adapt egg-laying behaviour to past experience als ... | 2015 | 25982411 |
| larvicidal activity against aedes aegypti of foeniculum vulgare essential oils from portugal and cape verde. | dengue is a potentially fatal mosquito-borne infection with 50 million cases per year and 2.5 billion people vulnerable to the disease. this major public health problem has recurrent epidemics in latin america and occurred recently in cape verde and madeira island. the lack of anti-viral treatment or vaccine makes the control of mosquito vectors a high option to prevent virus transmission. essential oil (eo) constituents can affect insect's behaviour, being potentially effective in pest control. ... | 2015 | 25973508 |
| imidacloprid impairs the post-embryonic development of the midgut in the yellow fever mosquito stegomyia aegypti (=aedes aegypti). | the mosquito stegomyia aegypti (=aedes aegypti) (diptera: culicidae) is a vector for the dengue and yellow fever viruses. as blood digestion occurs in the midgut, this organ constitutes the route of entry of many pathogens. the effects of the insecticide imidacloprid on the survival of st. aegypti were investigated and the sub-lethal effects of the insecticide on midgut development were determined. third instar larvae were exposed to different concentrations of imidacloprid (0.15, 1.5, 3.0, 6.0 ... | 2015 | 25968596 |
