Tsetse flies are the sole vectors of human African trypanosomiasis throughout sub-Saharan Africa. Both sexes adult tsetse feed exclusively on blood and contribute to disease transmission. Notable differences between other include obligate microbial symbioses, viviparous reproduction, lactation. Here, we describe sequence annotation 366-megabase Glossina morsitans genome. Analysis genome 12,308 predicted protein-encoding genes led multiple discoveries, including chromosomal integrations...
The Mediterranean fruit fly (medfly), Ceratitis capitata, is a major destructive insect pest due to its broad host range, which includes hundreds of fruits and vegetables. It exhibits unique ability invade adapt ecological niches throughout tropical subtropical regions the world, though medfly infestations have been prevented controlled by sterile technique (SIT) as part integrated management programs (IPMs). genetic analysis manipulation has subject intensive study in an effort improve SIT...
Invasive species represent a global concern for their rapid spread and the possibility of infectious disease transmission. This is case invader Aedes albopictus, Asian tiger mosquito. vector medically important arboviruses, notably chikungunya (CHIKV), dengue (DENV) Zika (ZIKV). The reconstruction complex colonization pattern this mosquito has great potential mitigating its and, consequently, risks.Classical population genetics analyses Approximate Bayesian Computation (ABC) approaches were...
Tsetse flies (Glossina sp.) are the vectors of human and animal trypanosomiasis throughout sub-Saharan Africa. distinguished from other Diptera by unique adaptations, including lactation birthing live young (obligate viviparity), a vertebrate blood-specific diet both sexes, obligate bacterial symbiosis. This work describes comparative analysis six Glossina genomes representing three sub-genera: Morsitans (G. morsitans morsitans, G. pallidipes, austeni), Palpalis palpalis, fuscipes), Fusca...
Abstract The mosquito Aedes albopictus is an invasive species first detected in Europe Albania 1979, and now established 28 European countries. Temperature a limiting factor activities the transmission of associated arboviruses namely chikungunya (CHIKV) dengue (DENV). Since 2007, local transmissions CHIKV DENV have been reported mainland Europe, mainly South Europe. Thus, critical question how far north could occur. In this context, Albanian infestation by Ae. interest because present up to...
Abstract Background Aedes albopictus , the Asian tiger mosquito, which is listed among world's 100 most dangerous invasive species, main vector of chikungunya, dengue and Zika viruses. This mosquito species has rapidly dispersed invaded much globe assisted by its life history traits high propagule pressure driven human activities. currently widespread across mainland Europe Mediterranean region, including islands. Cyprus remained free Ae. until October 2022, when specimens were recorded for...
Tsetse flies (Glossina spp.) are the cyclical vectors of Trypanosoma spp., which unicellular parasites responsible for multiple diseases, including nagana in livestock and sleeping sickness humans Africa. Glossina species, morsitans (Gmm), Whole Genome Sequence (WGS) is now available, have established symbiotic associations with three endosymbionts: Wigglesworthia glossinidia, Sodalis glossinidius Wolbachia pipientis (Wolbachia). The presence both natural laboratory populations horizontal...
The dramatic worldwide expansion of Aedes albopictus (the Asian tiger mosquito) and its vector competence for numerous arboviruses represent a growing threat to public health security. Molecular markers are crucially needed tracking the rapid spread this mosquito obtain deeper knowledge population structure. This is fundamental requirement development strict monitoring protocols improvement sustainable control measures.Wild samples from putative source areas newly colonised regions were...
Abstract The mosquito Aedes albopictus is one of the most dangerous invasive species. Its worldwide spread has created health concerns as it a major vector arboviruses public significance such chikungunya (CHIKV). Dynamics different genetic backgrounds and admixture events may have impacted competence for CHIKV in adventive populations. Using microsatellites, we infer structure populations across expansion areas that then associate with their genotypes. Here show demographic history Ae....
In the last 40 years, Asian tiger mosquito Aedes albopictus, indigenous to East Asia, has colonized every continent except Antarctica. Its spread is a major public health concern, given that this species competent vector for numerous arboviruses, including those causing dengue, chikungunya, West Nile and recently emerged Zika fever. To acquire more information on ancestral source(s) of adventive populations overall diffusion process from its native range, we analyzed mitogenome variation 27...
Insects with restricted diets rely on obligate microbes to fulfil nutritional requirements essential for biological function. Tsetse flies, vectors of African trypanosome parasites, feed exclusively vertebrate blood and harbour the endosymbiont Wigglesworthia glossinidia. Without , tsetse are unable reproduce. These symbionts sheltered within specialized cells (bacteriocytes) that form midgut-associated bacteriome organ. To decipher core functions this symbiosis tsetse's survival, we...
Abstract The phytophagous insects of the Tephritidae family offer different case histories successful invasions. An example is Bactrocera dorsalis sensu stricto , oriental fruit fly which has been recognized as a key pest Asia and Pacific. It known to have potential establish adventive populations in various tropical subtropical areas. Despite economic risk associated with putative stable presence this fly, genetic aspects its invasion process remained relatively unexplored. Using...
Abstract Background The medfly, Ceratitis capitata , is a highly invasive agricultural pest that has become model insect for the development of biological control programs. Despite research into behavior and classical population genetics this organism, quantity sequence data available limited. We have utilized an expressed tag (EST) approach to obtain detailed information on transcriptome signatures relate variety physiological systems in medfly; emphasizes reproduction, sex determination,...
Sexual maturation and mating in insects are generally accompanied by major physiological behavioural changes. Many of these changes related to the need locate a mate subsequently, case females, switch from searching oviposition behaviour. The prodigious reproductive capacity Mediterranean fruit fly, Ceratitis capitata, is one factors that has led its success as an invasive pest species. To identify molecular status male female medfly, microarray-based gene expression approach was used...
Phytophagous insects of the genus Bactrocera are among most economically important invasive fruit fly pests. In 2003, an unknown species was found in Kenya. First identified as 'aberrant form' Asian B. dorsalis complex, it later recognized a new species, invadens. Within 2 years its discovery, recorded several African countries, becoming quarantine pest. As this discovered only recently, no data available on invasion pattern Africa. This pilot study attempts to infer from genetic dynamic...
The Mediterranean fruit fly (or medfly), Ceratitis capitata (Wiedemann; Diptera: Tephritidae), is a serious pest of agriculture worldwide, displaying very wide larval host range with more than 250 different species and vegetables. Olfaction plays key role in the invasive potential this species. Unfortunately, pheromone communication system medfly complex still not well established. In study, we report isolation chemicals emitted by sexually mature individuals during "calling" period...
Insect seminal fluid is a complex mixture of proteins, carbohydrates and lipids, produced in the male reproductive tract. This transferred together with spermatozoa during mating induces post-mating changes female. Molecular characterization proteins Mediterranean fruit fly, Ceratitis capitata, limited, although studies suggest that some these are biologically active.
Abstract The Mediterranean fruit fly, Ceratitis capitata , is a destructive agricultural pest with long history of invasion success. This has been affecting different regions the United States for past 30 years, but number studies medfly bioinfestations focused on situation in California. Although some progress made terms establishing origin infestations, overall status this area remains controversial. Specifically, do flies captured over years represent independent infestations or...
Multilocus enzyme electrophoresis data from 26 polymorphic loci (124 alleles) were used to analyze the genetic aspects of worldwide colonization Ceratitis capitata (medfly). Eighty-two samples 17 populations collected six regions throughout species range: Africa, extra-Mediterranean islands (Madeira and Gran Canaria), Mediterranean region, Latin America (Guatemala), Pacific (Hawaii), Australia. The variability parameters (H, P, A) reveal that geographical dispersal medfly its ancestral...
Abstract As a result of their rapid expansion and large larval host range, true fruit flies are among the world's most important agricultural pest species. Among them, Ceratitis capitata has become model organism for studies on colonization invasion processes. The genetic aspects medfly process have already been analysed throughout its with exception Australia. Bioinvasion into Australia is an old event: were first captured in 1895, near Perth.
