For instance, if the climate is warming, can we expect that vector-borne parasitic diseases of the tropics will invade more developed countries.
I certainly think there will be and are associations between climate change and vector-borne parasitic diseases of the tropics. Parasite, like other organisms, are relevant to the study of climate change. For some that that are abundant and conspicuous they may be ideal models. For others, that are long-lived, tracking populations across time with respect to a suite of factor and climate change can be informative.
For your specific example, it is likely that the range and distribution of vector-born parasitic diseases will be influenced by the host and the parasites' response to climate change, and these may be particularly species and perhaps population specific. To better answer your question, I think you need to refine the focus of your question to a specific vector-borne parasitic disease, as parasites are diverse, and have incredibly variable life cycles and impacts on hosts. Accordingly, answering your question with a generalized statement is difficult and can be inaccurate.
of course , parasites will affected with climate change because almost of it need intermediate host which their present depend on environmental Circumstances.
As Rachel has commented, a single answer will not cover the diversity of parasites and the effects of climate change upon them or on diseases they may cause. Examples of the influence of climate change:

Temperature,humidity and alot of other environmental factors are very crucial in the life cycle and transmission dynamics of may parasitic infections and they are all affected by climate change. Don't forget also that hosts and vectors can be affected by climate change.
this is basic thing in distribution and prevulance of the parasites

parasites will affected with climate change because almost of it need intermediate host which their present depend on environmental Circumstances
, parasites will affected with climate change because intermediate host and final host also affected by environmental factors
Every organism has an optimum weather condition under which it can survive, mate and reproduce, hence parasitic organisms and their vectors are affected by any slight change in weather condition which either favours their existence or hinders it. A good example is the soil transmitted helminths. e.g Hookworm. This parasite has an optimum temperature range at which the ova embryonates and develops into an infective stage in the soil, if the temperature of the soil upon which the ova drops is altered due to climate change the development of the parasite will be hindered thereby reducing the chances of being transmitted to another host . Another example is that, higher cases of malaria disease are recorded during raining season due to high abundance of the vector (mosquitoes) during this period.
In furtherance to Akinola's comment, climate change is very relevant to parasitology because it greatly affect the distribution of parasites vectors. Mosquito species specific to a particular geographical region are now found where they hitherto do not occur a typical example is the Asian tiger mosquito Aedes albopictus which origin is Asian involved in the recent outbreak of Zika virus in the Americas
To further expand this discussion, it has been shown that insect vectors are sensitive to changes in temperature, a slight increase usually promoting an increase in distribution and recruitment as mentioned in a publication by Atehmengo et al. (2014). As such, a general increase in temperatures may make it possible for an increase in reports of vector-borne parasitic diseases to be found in areas it hasn't before. For instance, in increasingly higher altitudes of mountains where previously the vector had not been able to proliferate due to temperatures and other abiotic factors that were not conducive to its survival. On another note, it has been suggested by Cizauskas et al. (2017) that parasites may also be negatively affected by a change in climate as any other group of trophic organisms due to their sensitivity to temperature changes as well as risks affiliated with coexistence. Taking both works into account, climate change could prove to benefit the transmission of vector-borne parasitic disease. However, this would only be up until a certain extent where, at this point, extinction may instead result due to changes going beyond the optimal conditions necessary for the vector.
