The Phlebotominae are a subfamily of the family Psychodidae. In several countries, their common name is sand fly ; but that name is also applied to other flies known as sandflies.

Phlebotominae

Control of phlebotomine Diptera: Psychodidae leishmaniasis vectors. Phlebotomines are of medical and veterinary concern as they vector leishmaniasis, bartonellosis and some arboviruses. The adaptations of some species to places modified by humans bring these vectors into contact with dwellings, which can facilitate disease transmission, and the vector control strategies adopted have rendered controversial results. Regarding leishmaniasis, for instance, which vector and reservoirs control can be effective, there is an assumption that the incidence of human infection is directly related to the number of infectious dogs, as well as to entomological factors. Therefore, vector control can provide a cheaper and more practical solution to prevent cases of leishmaniasis. Nevertheless, due to the complexity of the factors involved, chemical control is still essential, and biological insecticides and insecticide plants, for example, represent areas for study that should be encouraged and developed since they show promising results. This paper summarizes the control strategies adopted so far, especially the methods and efficiency of the entomological components of leishmaniasis control programs.

In some foci of leishmaniasis, the vectors are unknown and it is certain that more species will be added to the list. This is a constraint in devising means of controlling the vectors and thus reducing the risk of infection. Most importantly, so little is known about the terrestrial breeding sites of sand flies that any attempt to control them by attacking the peri-marginal stages is impractical.

Sri Lanka. Phlebotomine sand flies Psychodidae: Diptera of Sri Lanka: a review on diversity, biology and bionomics. Phlebotomine sand flies are medically important insects widespread throughout the world and responsible for the transmission of several diseases to humans and other animals including leishmaniasis and sand fly fever. In Sri Lanka, a total of 22 species of sand flies belonging to two genera, namely: Phlebotomus and Sergentomyia, have been recorded with 6 and 16 species, respectively. The current study reports a complete list of the species of sand flies reported from Sri Lanka with a review on global and local distribution, biology and bionomics of each species as per published literature up to June Abonnenc E.

Sand flies are the insects responsible for transmitting Leishmania parasites, the causative agents of leishmaniasis in humans. However, the effects of sand fly breeding sites on their biology and ecology remain poorly understood. Herein, we studied how larval nutrition associated with putative breeding sites of the sand fly Lutzomyia longipalpis affects their oviposition, development, microbiome, and susceptibility to Leishmania by rearing L. The results showed that female L. Typical gut microbial profiles were found in larvae reared upon cashew leaf litter. Adult females from larvae reared on substrate collected in chicken coops were infected with Leishmania infantum , indicating that they were highly susceptible to the parasite. In conclusion, the larval breeding sites can exert an important role in the epidemiology of leishmaniasis.

The Biology and Control of Leishmaniasis Vectors

Беккер здесь… Я чувствую, что. Он двигался методично, обходя один ряд за другим. Наверху лениво раскачивалась курильница, описывая широкую дугу. Прекрасное место для смерти, - подумал Халохот.

Стратмор сразу заметил изумление, мелькнувшее в ее глазах, и взволнованно изложил свой план: - Если бы я получил ключ, то смог бы взломать наш экземпляр Цифровой крепости и внести нужные изменения… - Черный ход, - сказала Сьюзан, мгновенно забыв о том, что Стратмор ей лгал. Она все поняла.  - Вроде Попрыгунчика.

 Вышла небольшая заминка, - сказал американец. - Это невозможно! - рявкнул Нуматака.  - Вы обещали, что они будут у меня сегодня до конца дня. - Произошло нечто непредвиденное.

 Есть, но отец ее заблокировал. Он думает, что я балуюсь наркотиками. - А это не так? - спросил Беккер холодно, глядя на ее припухший локоть.

 Вы этого не сделаете! - крикнул Хейл.  - Я все расскажу. Я разрушу все ваши планы. Вы близки к осуществлению своей заветной мечты - до этого остается всего несколько часов. Управлять всей информацией в мире.

Лампы, замигав, зажглись.

Vector control remains a key component of many anti-leishmaniasis programs and probably will remain so until an effective vaccine becomes available.
