However, the combined effects of local management and landscape factors on communities of natural enemies as well as the cascading effects on pest infestations are rarely addressed, especially . Introduction. Species identification of sand flies by MALDI-TOF MS is feasible and represents a novel promising tool to improve biological and epidemiological studies on these medically important insects. Keep in mind that all insect species are also suppressed by naturally occurring organisms and environmental factors, with no human input. Control of sand flies can be difficult because immature habitats are poorly understood, which makes them difficult to target with available control measures. The major emphasis of W2185 scientists is the control of insect pests and weedy plants.

Abstract Background: Phlebotomine sand flies are prominent vectors of Leishmania parasites that cause leishmaniasis, which comes second to malaria in terms of parasitic causative fatalities globally. Biological control is a component of an integrated pest management strategy. Phlebotomine sand flies are incriminated in the transmission of several human and veterinary pathogens. There are three primary methods of using biological control in the field: 1) conservation of existing natural enemies, 2) introducing new natural enemies and establishing a permanent population (called "classical biological control"), and 3) mass rearing and periodic release, either on a seasonal basis or inundatively.
