Background Visceral leishmaniasis (VL) is a deadly vector-borne disease. Approximately 90% of Indian VL cases occur in Bihar, where the sand fly, Phlebotomus argentipes, principal vector. Sand fly control Bihar consists indoor residual spraying (IRS), practice inner walls village dwellings with insecticides. Prior researchers have evaluated success IRS-control by estimating vector abundance houses, but number sampling periods (n = 2–3) were minimal, and outdoor-resting P. argentipes...
Blood-sucking phlebotomine sand flies (Diptera: Psychodidae) transmit leishmaniasis as well arboviral diseases and bartonellosis. Sand fly females become infected with Leishmania parasites them while imbibing vertebrates' blood, required a source of protein for maturation eggs. In addition, both males consume plant-derived sugar meals energy. Plant may comprise sugary solutions such nectar or honeydew (secreted by plant-sucking homopteran insects), phloem sap that obtain piercing leaves...
Plague (Yersinia pestis) and zoonotic cutaneous leishmaniasis (Leishmania major) are two rodent-associated diseases which vectored by fleas phlebotomine sand flies, respectively. In Central Asia, the great gerbil (Rhombomys opimus) serves as primary reservoir for both in most natural foci. The systemic insecticide fipronil has been previously shown to be highly effective controlling flies. However, impact of a fipronil-based rodent bait, on flea fly abundance, never reported Asia. A field...
Plague is a virulent zoonosis, vectored by fleas, posing danger to black-tailed prairie dogs (BTPDs) (Cynomys ludovicianus), black-footed ferrets (Mustela nigripes), and humans in North America. During prior research, fipronil grain bait (0.005%) applied at rates of 1-½ cup/burrow, reduced flea abundance > 95–100% when three times February–March northern Colorado. The objective the current study was determine efficacy against fleas Colorado application (½ cup/burrow) frequencies (1–2...
Lake Chapala is the largest tropical lake in Mexico. The objectives of this study were to determine bioaccumulation Hg fish and evaluate potential impacts diet aquatic birds, particularly American white pelican (AWPE), Chapala. concentrations three species ranged from 0.021 0.568 μg/g wet weight. Mercury was positively significantly correlated with total length (R2 = 0.44, P < 0.05). δ15N values San Antonio Reservoir 0.69, 0.001 R2 0.40, 0.001, respectively). However, bird feathers not...
Visceral leishmaniasis (VL), transmitted by the sand fly, Phlebotomus argentipes, is frequently reported on Indian subcontinent where its basic ecology largely unknown. Our objective was to evaluate effectiveness of sugar solution (10%), containing colored food dye (0.5%) applied peridomestic vegetation, mark P. argentipes and subsequently estimate horizontal movement capturing dye-marked specimens in CDC light traps a village Bihar, India. From September 30 November 27, 2016, total 667...
Abstract The Attwater's prairie‐chicken (APC; Tympanuchus cupido attwateri ) was listed as an endangered species in 1967, and since then multiple studies have addressed ecological human factors that may limited their population recovery. In this study, we used stable isotopes of carbon nitrogen (δ 13 C δ 15 N) conjunction with Bayesian mixing models to determine current diets APCs at the Attwater Prairie Chicken National Wildlife Refuge (APCNWR), compare them past derived from isotopic...
The state of Texas has the highest population feral hogs, Sus scrofa, than any in U.S.A. expanding abundance and distribution hogs throughout North America is testimony to their ability adapt differing environmental habitat conditions. We evaluated movements activity 18 fitted with Global Positioning System (GPS) collars between March 2015 through July 2017 Panhandle, U.S.A., following three toxicant field studies. investigated response individual, weather, variables using generalized linear...
The distribution of feral hogs throughout North American has increased dramatically since their introduction. use toxicants proven to be a n effective tool in controlling hog numbers several countries. Using data from 13 GPS hogs, we compared movements and space control treated between pre-baiting baiting phases 3 toxicant field tests. Generalized linear mixed models were used explain prospective changes movements. In addition, evaluated the distance toxicant-killed carcasses bait stations,...
