“…The lowest density of Wolbachia in females of D. citri during the reproductive period as compared to males of D. citri is contrary to previous reports on many other species [13,76,77]. Little is known on the adaptive cost of infection and the presumable differences in the proliferation rate of Wolbachia in the reproductive tissues of males and females [13,76,77], but the lower density of Wolbachia in older females could be a consequence of the reduced growth rate after t* (third instar) and/or due to the process of transovarian transmission. Additionally, factors related with the adaptive cost of infection and the presumable differences in the proliferation rate of Wolbachia in the reproductive tissues of males and females need further examination [13,76,77].…”

“…No entanto, os simbiontes facultativos, normalmente resultantes de aquisições mais recentes no contexto filogenético, estabelecem interações diversas, podendo contribuir de forma positiva para a nutrição e tolerância a fatores de estresse (BURKE; FIEHN; FELDHAAR, 2011;LUKASIK et al, 2013), mas podem também afetar a aptidão biológica do hospedeiro de várias maneiras. Como exemplo, o simbionte intracelular facultativo Wolbachia, amplamente distribuído entre os insetos, induz uma série de manipulações reprodutivas, tais como feminização, parternogênese, morte de machos e incompatibilidade citoplasmática, resultantes na distorção da razão sexual do hospedeiro (WERREN; CORREA;BALLARD, 2012). No entanto, apesar de inúmeros relatos da participação auxiliar desse simbionte em processos de defesa imunológica do hospedeiro (RANCES et al, 2012), na tolerância a fontes de estresse (BIAN et al, 2010), na contribuição nutricional (HOSSOKAWA et al, 2010), na fecundidade do hospedeiro (DEDEINE et al, 2001;, há também inúmeros relatos do custo adaptativo da associação a esse simbionte, que leva à menor longevidade e aptidão reprodutiva (FLEURY et al, 2000;WEEKS;REYNOLDS;HOFFMANN, 2001).…”
