DOI: 10.1002/jcp.30806
Abstract: In insects, the last stage of oogenesis is the process where the chorion layers (eggshell) are synthesized and deposited on the surface of the oocytes by the follicle cells. Protein homeostasis is determined by the… read more here.

DOI: 10.1016/j.actatropica.2019.05.022
Abstract: Triatomine bugs are considered nocturnal insects that feed on the blood of vertebrates and remain hidden inside narrow shelters during daylight hours. Nevertheless, it is not clear whether these insects become active and leave their… read more here.

DOI: 10.1016/j.ibmb.2018.10.004
Abstract: Rhodnius prolixus is one of the most important vectors of Chagas disease in Central and South America for which repellents and attractants are sorely needed. Repellents like DEET, picaridin, and IR3535 are widely used as… read more here.
