Ectocrine Technologies LLC is a biotech company dedicated to studying the positive human physiological effects of salivary secretions of hematophagous arthropods, such as mosquitos, as an essential source of molecules for human well-being and development.
All the species of the subfamily Vandelliinae are exclusively hematophagous, sucking blood from the gills of other fishes (Kelley & Atz, 1964; Machado & Sazima, 1983; Zuanon & Sazima, 2005).
Trophic guild: C: carnivorous, F: frugivorous, I: insectivorous, N: nectarivorous, H: hematophagous. The main guild is shown before the parentheses.
According to the World Health Organization leishmaniasis is one of the most serious diseases caused by protozoan parasites, with approximately 12 million cases reported in the world.1 It is caused by more than 20 Leishmania species which are transmitted by hematophagous sandflies of the Phlebotomus genus in the Old World and the Lutzomyia genus in the New World, and more than 90 sandfly species are identified as probable vectors.2 The disease occurs in varying presentations, from the self-limited and even self-healing cutaneous forms to fatal systemic disease.

Haemogregarines are geographically ubiquitous parasites that infect all groups of terrestrial vertebrates and an array of hematophagous arthropods (4).
As obligate hematophagous ectoparasites, ticks are recognized as notorious arthropod vectors which transmit the most diversity of pathogens and rank second only to mosquitoes causing life-threatening zoonotic diseases (Sonenshine and Roe, 2014).
For this reason, studies have been focusing on the pharmacological potential of molecules in the saliva from different hematophagous arthropods to treat inflammatory/autoimmune conditions.
The pharmacologically active components secreted in their saliva help ticks circumvent host defenses such as haemostatic and immune responses of the host, thereby enabling blood feeding in hematophagous arthropods [11].
The common compounds identified as well as others previously identified as attractive to other hematophagous arthropods were evaluated for their ability to stimulate and attract the major onchocerciasis vectors in Africa (Simulium damnosum sensu lato) and Mesoamerica (Simulium ochraceum s.l.).
They are very important obligate hematophagous ectoparasites and have worldwide distribution [1, 2].
