This study assessing the infestation rate of fruit fly species on Solanum aethiopicum,Solanum lycopersicum,and Capsicum spp,using incubation method,was conducted in Agricultural entomology laboratory of Research Centre in Natural Sciences(CRSN)Lwiro,at Kabare in The South Kivu Province in eastern part of the Democratic Republic of Congo.Five species of Tephritidae flies observed,i.e.Bactrocera dorsalis,B.latifrons,Dacus bivitatus,Ceratitis capitata,and Zeugodacus Cucurbitae.The highest infestation rate was observed on B.dorsalis and following C.capitata in those solanaceous chilli pepper(C.frutescens),eggplant(S.aethiopicum)and tomato(S.lycopersicum)than Z.cucurbitae,B.latifrons and D.bivittatus.However,the localities Kamakombe,Buhandahanda,Lwiro,Bishibiru have predominant in the majority of hosts in chilli pepper,eggplant and tomato. 展开更多

Larval surveys were done at indoors and outdoors water containers of five types. Prevalence rate of larval density larvae was investigated monthly by standard indices. The highest infestation rate of the container index (CI) was in June 2018 (56.52%), the second highest was in July 2017 (48.36%) and the lowest rate was in April 2017 (5.07%);those of the Jar index (JI) was highest (36.49%) in June and second highest rate (23.8%) was in October 2017. Reasoning the Metal drum (MI) was highest (13.95%) in June 2018 and second highest (6.25%) was in July 2017. The larval infestation rate of Earthen pot (EI) was highest (42.1%) in July 2017. The larval incident rate in almost all indices showed that the highest rate was at the beginning of monsoon season, in June and July, while in the remaining months, the larval incident rate was found to decrease due to the application of insecticides in the study area by the Township Public Health Department. However, the application of insecticides did not cover all the breeding sites of the mosquitoes, the water puddles under their houses were left to apply the insecticides. The positive larval incident rate was assessed by Household (HI), Container index (CI), Breteau index (BI). The highest and second highest positive larval incident rates were all in June 2018 and July 2017 in all indices, HI (27.3% and 23.4%), CI (56.52% and 48.36%), BI (17.56% and 16.79%) and SI (28.49% and 24.38%) respectively. The lowest rate in all indices was 2.56% (HI), 5.07% (IC), 2.67% (BI) and 1.91% (SI) in April. In this study, the fluctuation of indices of infestation rates and positive larval index value was positively correlated in similar trends in the study months. The reason for difficult control measure depends on the water sources under their houses and remains stagnant throughout the year, even in the dry season. High incident and death rates of the children due to Dengue/Dengue Haemorrhagic fever patients in June and July could not be directly correlated with the prevalence of <i>Aedes aegypti</i>. The control measure is needed to wash out the water source under the houses and to apply the insecticides to the all breeding sites. 展开更多

In this paper,we present an attempt at analyzing the seasonal pattern of the Babesiosis transmission dynamics in bovine and tick populations.The infestation rate plays an important role in the variation of infection.In this logic,we set out a mathematical model with variable infestation rate for the evolution of babesiosis disease.Using the(0,2)-Jacobi multi-wavelets method combined with the decoupling and quasi-linearization technique,we demonstrate the validity and applicability of our model.Then,a set of experimental data is used to validate the proposed model under the same operating conditions.The results of numerical simulations are provided to show the impact of seasonality on the transmission dynamics of Babesiosis.Eventually,a numerical study of the model varying the control parameters of babesiosis shows different scenarios about the spread of the disease. 展开更多
