It is a diurnal mosquito, and the oviposition sites for the species include tree holes. The eggs of Hg. tropicalis used in this study were from females captured on Combú Island, situated across from the city of Belém, Guajará Bay, state of Pará, at 1°25'S latitude and 48°25'W longitude. The eggs are elliptical and average 575 µm long with a width of average 144 µm. The ventral surface of the chorionic reticulum has regular chorionic cells with hexagonal and sometimes pentagonal ornamentation. Each chorionic cell has a thick external chorionic reticulum with regular borders. The interior of the chorionic cells have small, evenly distributed tubercles, and the dorsal external chorionic reticulum appears porous. The micropylar apparatus, located on the anterior area of the egg, was formed by a collar with a well-developed frame. Centrally, the micropylar disc had a diameter of ?20 µm and the micropylar orifice is 2.1 µm in diameter. These data may enable construction of taxonomic keys for identifying eggs of Haemagogus species. specialized FIEVRE JAUNE TRANSMISSION VECTEUR MOUSTIQUE DENSITE DE POPULATION SAISON HUMIDE COEFFICIENT DE CORRELATION VARIATION SAISONNIERE ANALYSE STATISTIQUE BRESIL 052CULARB03 41 2 117-122 2006 0165-0521 https://www.documentation.ird.fr/hor/fdi:010036414 10.1080/01650520500398662 0165-0521 [F B010036414] https://www.documentation.ird.fr/hor/fdi:010036414 https://www.documentation.ird.fr/intranet/publi/2025-08/010036414.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2025-10-23 fdi:010036414 fre
