BackgroundThe aim of this study was to address the role of chickens as bloodmeal sources for female Lutzomyia longipalpis and to test whether chicken blood is harmful to Leishmania parasite development within the sand flies. Bloodmeal ingestion, excretion of urate, reproduction, fecundity, as well as Leishmania infection and development were compared in sand flies fed on blood from chickens and different mammalian sources.ResultsLarge differences in haemoglobin and protein concentrations in whole blood (dog>human>rabbit> chicken) did not correlate with differences in bloodmeal protein concentrations (dog = chicken>human>rabbit). This indicated that Lu. longipalpis were able to concentrate bloodmeals taken from different hosts using prediuresis and this was confirmed by direct observation. Sand flies fed on chickens or dogs produced significantly more eggs than those fed on human blood. Female Lu. longipalpis retained significantly more urate inside their bodies when fed on chicken blood compared to those fed on rabbit blood. However, when the amounts of urate excreted after feeding were measured, sand flies fed on rabbit blood excreted significantly more than those fed on chicken blood. There was no difference in female longevity after feeding on avian or mammalian blood.Sand flies infected via chicken blood produced Leishmania mexicana infections with a similar developmental pattern but higher overall parasite populations than sand flies infected via rabbit blood.ConclusionsThe results of this study help to define the role that chickens play in the epidemiology of leishmaniasis. The present study using a Lu. longipalpis/L. mexicana model indicates that chickens are suitable hosts to support a Lu. longipalpis population and that chicken blood is likely to support the development of transmissible Leishmania infections in Lu. longipalpis.

SummaryColorado potato beetles (CPB) overwinters as adults in the soil, thus, their survival is related with their energy reserves. The present study examined the biochemical changes in adults treated with sub-lethal concentrations (≤LC30) of pyriproxyfen. First, both the plants and overwintered adults were sprayed with different levels of pyriproxyfen (0, 250, 500 and 750 µl/l) under field conditions and were tested at 3, 6 and 12 days after treatment. Next, the adults from the first experiments were re-sprayed 1 week later with pyriproxyfen at the same concentrations and were re-sampled at 3, 6 and 12 days after the second treatment. The lipid, sugar, glycogen and protein levels of 4 males and 4 females were determined (mg/g; w/w). Results revealed a significant decline in lipid (87.7%), glycogen (50%) and caloric contents (75%) levels with respect to controls. Sugar and protein levels increased 7.89 and 5.79 times with respect to the controls. The best results were obtained at 250 µl/l of pyriproxyfen. The second round of testing demonstrated the additive effects of pyriproxyfen on bioenergetic reserves. Only the protein level showed a significant difference by sex. Keywords: Colorado potato beetle, lipids, carbohydrates, proteins, admiral, pyriproxyfen ÖzetPatates böceği, toprakta ergin olarak kışlamaktadır. Bu nedenle, onların hayatta kalmaları enerji rezervleri ile ilişkilidir. Bu çalışmada pyriproxyfenin alt öldürücü konsantrasyonları (≤LC30) uygulanmış erginlerdeki biyokimyasal değişiklikler incelenmiştir. İlk olarak, bitki ve kışlaktaki erginlere tarla şartlarında pyriproxyfen (0, 250, 500 ve 750 µl/l) farklı düzeylerde püskürtülmüş ve uygulamadan 3, 6 ve 12 gün sonra test edilmiştir. Birinci deneyden alınan erginlere 1 hafta sonra tekrar aynı konsantrasyonlarda pyriproxyfen uygulanmış ve 3, 6 ve 12 gün sonunda yeniden örneklenmiştir. 4 erkek ve 4 dişi bireyde lipit, şeker, glikojen ve protein düzeyleri (mg/g; a/a) tespit edilmiştir. Sonuçlar, kontrole göre lipid (% 87.7), glikojen (% 50) ve kalori içeriği (% 75) düzeylerinde önemli bir düşüş göstermiştir. Şeker ve protein düzeyleri kontrole göre 7.89 ve 5.79 kat artmıştır. En iyi sonuçlar, pyriproxyfenin 250 µl/l dozunda elde edilmiştir. Testin ikinci turu pyriproxyfenin biyoenerjik rezervler üzerindeki ilave etkilerini göstermiştir. Sadece protein düzeyi cinsiyete göre anlamlı bir farklılık göstermiştir.

“…Although natural membranes can also be applied, there are artificial options to replace the use of animal skin [2]. The large number of different feeders available for mosquito species is notable and the availability of artificial systems for arachnids, phlebotomines and triatomines is also considerable [8,12,13,19,21].…”

“…It is a crucial point to be addressed since the argument here is to promote an ethical conscience based on 3Rs principle to increase the artificial feeder application in substitution for live animal use to blood-feed invertebrate vectors. In fact, although some articles reported negative effects on fecundity caused by artificial blood-feeding for Rhodnius prolixus and Simulium damnosum [22,23], there are many works showing positive examples in which colonies maintained by artificial feeders are comparable to live animal-fed counterparts for different species [9,11,16,18,21,[24][25][26].…”
