Phlebotominae (Diptera: Psychodidae) from northeastern Pará, Brazil, with expansion of the known distribution of Evandromyia andersoni

Abstract

OBJECTIVE:

To identify the composition of sand fly species in the municipality of Cachoeira do Piriá, Pará State, Brazil.

MATERIALS AND METHODS:

Entomological captures were carried out with CDC light traps installed at 1.5 above the ground for 12 h in 80 sampling points at the urban and rural areas of Cachoeira do Piriá, from August to October 2021. After slide-mounting in Canada balsam the specimens were identified, quantified, and the data were organized in electronic spreadsheets to perform descriptive statistics.

RESULTS:

A total of 544 specimens (28 species of 12 genera) were captured. Nyssomyia antunesi, Nyssomyia fraihai, Evandromyia infraspinosa and Bichromomyia flaviscutellata were the most frequent ones. Species with vectorial importance were identified (Bi. flaviscutellata, Lutzomyia gomezi, Ny. antunesi, Psychodopygus davisi, Psychodopygus ayrozai and Psychodopygus complexus), besides a specimen of Evandromyia andersoni the first record of its occurrence in Pará.

CONCLUSION:

There are important species in the transmission of leishmania in Cachoeira do Piriá that need investigation. The occurrence records of Ev. andersoni for the state of Pará increases the known distribution area of ​​the species in Brazil and indicates that the number of sand flies in Pará may be even greater.
