“…In this report, we evaluated the persistence and efficiency of 0.025 M RbCl and 0.0015 M CrCl 3 to mark T. brasiliensis nymphs. Trace elements have been successfully used to mark at least eight orders and 30 families of insects, with RbCl being the most frequently used marker (Hagler & Jackson 2001, Maciel-de-Freitas et al 2004. However, our results showed that RbCl had a very variable positivity and a decreasing persistence with the stage of T. brasiliensis.…”

“…The dispersal ability of Ae. albopictus has been studied using a mark–release–recapture approach by several authors, but these studies were focused mainly on females and data are lacking for males, which are most important when applying strategies in which only males are released (Niebylski & Craig, 1994; Takagi et al , 1995; Maciel‐de‐Freitas et al , 2004, 2006). The removal of Wolbachia , as shown in this study, has no adverse impact on male fitness.…”

Cytoplasmic incompatibility (CI) induced by maternally inherited Wolbachia bacteria is a potential tool for the suppression of insect pest species with appropriate patterns of infection. The Asian tiger mosquito Aedes albopictus (Skuse) (Diptera: Culicidae) is known to be infected by two strains of Wolbachia pipientis Hertig (Rickettsiales: Rickettsiaceae), wAlb A and wAlb B, throughout its geographical distribution. This infection pattern theoretically restricts the application of CI-based control strategies. However, Wolbachia can be horizontally transferred using embryonic microinjection to generate incompatible transfected lines harbouring a single new strain of Wolbachia. In order to assess the feasibility of this approach, the effects of Wolbachia removal on mosquito fitness need to be clearly evaluated as the removal of natural superinfection is an inescapable step of this approach. Previous research has shown that uninfected females, produced by antibiotic treatment, showed a decrease in fitness compared with those infected with Wolbachia. In this study, the effect of Wolbachia removal on male fitness was investigated. Longevity and reproductive potential (mating competitiveness and sperm capacity) were assessed in both laboratory cages and greenhouses. No differences were observed between uninfected and infected males with respect to longevity, mating rate, sperm capacity and mating competitiveness in either laboratory conditions or greenhouses. The preservation of fitness in males of Ae. albopictus deprived of natural Wolbachia infection is discussed in relation to the development of incompatible insect technique suppression strategies. Finally, the potential application of aposymbiotic males in mark-release-recapture studies is suggested.

The daily survival rate of Aedes aegypti (L) (Diptera: Culicidae) is one of the most important parameters in mathematical models of dengue transmission. In this report, we evaluate the effect of adult body size on the survival and dispersal rates of male and female Ae. aegypti, the primary dengue vector in Brazil. Independent of larval diet (i.e. size), the daily survival rate of females recaptured in the field was greater than that of males (smaller: t = 5.617; d.f. = 15; P < 0.05; larger: t = 4.241; d.f. = 16; P < 0.05). Larger males lived longer than smaller males (t = 2.2893; d.f. = 7; P < 0.05), but no size effect was observed for females (t =- 0.086; d.f. = 19; P= 0.932). The daily survival rate of smaller females was similar to that of larger females (0.712 and 0.730, respectively, as calculated by an exponential model, and 0.743 and 0.779, respectively, calculated by a non-linear model), and they dispersed further than larger females (mean distances travelled were 78.8 m and 40.9 m, respectively; t =- 10.22; d.f. = 323; P < 0.05). Adult body size did not influence male dispersal distances (t = 0.904; d.f. = 206; P= 0.367). Given our evidence that smaller females appear to have similar lifespans and evidence from other studies that they bite more frequently during a single gonotrophic cycle than larger females, our results suggest that smaller females have a higher vectorial capacity.
