![]() ![]() In this study, nymphal instars, morphological variation, vertical distribution, and population density in soil, and emergence phenology of nymphs of M. Information about ecological characteristics and some sustainable control measures of this species is urgently required for its control. The cicada Meimuna mongolica (Distant) (Hemiptera: Cicadidae) is one of the most important pests of economic forest in Guanzhong Plain of Shaanxi Province, China. Li, Qinglong Yang, Mingsheng Liu, Yunxiang Wei, Cong In this study, we characterized the bacterial microbiota of the highly polyphagous Mediterranean fruit fly, Ceratitis capitata (Diptera: Tephritidae), at different instars and when feeding on different host-plant speci.Įcology of Meimuna mongolica (Hemiptera: Cicadidae) Nymphs: Instars, Morphological Variation, Vertical Distribution and Population Density, Host-Plant Selection, and Emergence Phenology Previous studies have shown that microbial communities harbored within insects vary through ontogenetic development and among insects feeding on different host-plant species. Microorganisms are acknowledged for their role in shaping insects' evolution, life history and ecology. Malacrinò, Antonino Campolo, Orlando Medina, Raul F Palmeri, Vincenzo Instar- and host-associated differentiation of bacterial communities in the Mediterranean fruit fly Ceratitis capitata infestans would make this difference fade out if longer exposure times had been provided. Although the presence of chickens would decrease the overall percentage of infected bugs in short term experiments, the high rate of host change of T. Mixed blood meals on chickens and guinea pigs were detected in 12-21% of bugs. The bugs collected from inside or close to the guinea pigs' cages showed a higher infection rate (71-88% than those collected from the chickens' cages (22-32%. ![]() The additional presence of chickens relative to infected guinea pigs: (a significantly modified the spatial distribution of bugs (b increased significantly the likelihoods of having a detectable blood meal on any host and molting to the next instar (c did not affect the bugs' probability of death by predation and (d decreased significantly the overall percentage of T. infestans third instar nymphs were liberated in each replica, collected on day 14, and examined for infection and blood meal sources on day 32-36. The hosts were held unrestrained in individual metal cages inside a closed tulle chamber. The experiment consisted in two treatments: with chickens, including two chickens (non- susceptible hosts and two infected guinea pigs ( susceptible hosts, and without chickens, including only two infected guinea pigs. ![]() Effects of Non- Susceptible Hosts on the Infection with Trypanosoma cruzi of the Vector Triatoma infestans: an Experimental Modelĭirectory of Open Access Journals (Sweden)įull Text Available We tested experimentally the effects of the presence of non- susceptible hosts on the infection with Trypanosoma cruzi of the vector Triatoma infestans. ![]()
