Climate change is the present "buzz word" in all major discussions on environment. Complexity involved has often made the subject controversial and allowed divided opinion by people. Is climate change part of sound SCIENCE? or not is under review by many governmental and nongovernmental agencies? Is the called climate change an earthly phenomenon, it is human induced, is debatable? If proven the consequences can be far reaching both environmentally and economically. However, in the last decade enough evidence has been gathered showing human activity could be a prime reason for changes in global weather pattern, particularly increases in temperature. Therefore, temperature is probably the single most important environmental factor influencing insect behavior, distribution, development, survival and reproduction. This is also modify pest distribution, influence populations eventually alter global disease pattern. Now, therefore, what are the effects of climate change in distribution of pest and diseases in the environment? How could this be certainly brought harmful effects to human being?

Pests & diseases follow the food. For a lot of them, the food is in your blood. That food also comes to them through your sweat and your excrement. When it is hot, you sweat more---so much that almost-everything you touch has a trace of 'you-food' on it. Thus the more things you touch and -leave in the open air, the more 'you-food' there is available to random pests & diseases. The more 'you-food' you leave out there, the more they will be attracted to you. That's why some people wash their hands "too often." Me, that's why I keep all my clothes (including scarves & hats) in plastic bags when I'm not wearing them---to suffocate any pests or diseases that may have found their way onto them while I was wearing-or-carrying them.

So what do you do about them? Me: I try to stay clean (besides all the 'keeping clothes in bags') and have a couple cans of TAT bug-spray ... one for flying insects & one for crawlies

Thanks for sharing your opinion mythociate. True indeed that pests and diseases are the factors affecting food safety and supply. Human body heat is very attractant pest most especially mosquitoes. Roaches inside the house (german cockroach) will also dependent to human, they cannot live and exist without the human activity. Rodents were also proliferating inside the establishment if there was a sufficient supply of food. All these pests and other pest unmentioned were greatly affecting public health wherein they will carry different form of diseases it maybe through food poison or injecting infectious disease to human through sucking.

In my end , i just correctly follow all the cultural measures and and precautionary measures so that proliferation of such pests will not increasing its rates wherein they can possibly produce breeding reproduction. Further, being cognizant on their biological behavior helps us a lot on how to totally deter and control them without using the alternative recourse of chemical application.

Hi GilMegans, another good topic that you got here that makes me or perhaps our fellow myloters to think and re think before responding. It even prompted me to do some readings for I find it very interesting specially concerning our environment and the future environment for our grand-grand children. After reading an article, it made me seat back and dropped my shoulder - worry mode - what have we done to our environment today? An excerpt from the World Journal of Agricultural Sciences, series of 2012 in collaboration with the Intergovernment Panel on Climate Change, they have derive a conclusion that say, "Effect of climate change is more in temperate insects, it permits range expansion. Temperature cause the direct effects survival, growth and development, voltinism and dispersal of an insect or pest". Correct me if Im wrong, as i understood my readings, global warming affects pest evolution and/or as if they will mutate and/or tend to adapt the environment temperature. While other insects cant survive, but others will evolve. Lately, just around our backyard, I just saw an ant that is for me an usually big ant - as in - red ant with long legs but no wings and their eyes are distinguishable already. Are they now the effect of global warming. If so, then it is a very scary reality that is happening already, and truly health hazard. Hope you will enlighten us more on this article. This is just a painful awakening for a wonderful world we used to have.

Oh...! What more can I say. What a sad facts to learn. Truly, just now I realized and understood all these facts. While we are enjoying now all the resources that we have, on the other hand we are likewise depriving the next generation of having a good environment. You have explained well the topic above-mentioned, as such thank you so big GilMegans for sharing.

Thank you ma'am grace for a valuable response, appreciated a lot. Anyway, referring back to the topic, I tried to expound further some important matters concerning the effect brought by climate change related to pest and other form of disease my brougt therein. Based on the study and research, human induced climate change is primarily due to accumulation of green house gases in the atmosphere. This accumulation however, is the result of combustion of fossil and fuels, large scale deforestation and other form of habitat destruction including mainly of expansion of agriculture. The primary effect of increase green gases is an increase in global mean surface temperature. Associated with the increased temperatures are a number of other environmental parameters which will be affected and it is beyond the scope of climate change. This will actually restrict influence changes on urban pest and vector borne diseases they are associated with insects and temperature. Insects, however, are cold-blooded organism and they cannot regulate their body temperature. The temperature of their body is approximately the same as that of their immediate environment. Therefore, temperature is probably the single most important environmental factor influencing insect behavior, distribution, development, survival, and reproduction. Yes, you are right that climate change influence the evolution of insects and might experience one to five additional life cycle per season. This also caused in impact by their physiology and development directly of indirectly through its own physiology or by changes in hosts. I just had hoped tha this simple information could help people more cognizant on how climate change affect the human environment including however the spreading of pest and diseases...

Climate change will affect plant pests and diseases in the same way it affects infectious disease agents. In other words, the range of many insects will expand or change, and new combinations of pests and diseases may emerge as natural ecosystems respond to altered temperature and precipitation profiles. Any increase in the frequency or severity of extreme weather events, including droughts, heat waves, windstorms, or floods, could also disrupt the predator-prey relationships that normally keep pest populations in check.of course, it has a direct effect on us, our homes and our health.

Hi flagella08, yes you're right. The subject climate change and pest distribution is compex as it is inter dependent on a number of factors. Climate change is expected to alter not only the natural environment as a result of flooding or drought but also the urban environment as a result of changes in land use. It will greatly affecting the reproduction and distribution of pest and diseases that will caused harmful effect to human being.

Hi anquye123, Yes that's right climate change greatly affects infestation of pest in the ecosystem which will likewise influenced vector borne diseases to human being.

they will surely take a toll on it and the buzz word happens to be always to be taking an great impact of the temperature and reproduction for sure.The pests environment will surely be affected and most importantly,the adverse impacts happens to be affecting the human and cattle feed with great majority

Hi natliegleb, thanks for sharing your opinion. Well, pest will be increasing its population through temperature and other factors influencing the growth and breeding process of pests. It will affect not only to animals, food industry, environment but also to public health as well.

I believe the change in climate will allow pests that were not previously able to survive in a certain environment to then be able to. Not only will they survive but quite possibly survive better than in their native environment. This means more exposure to human and animals that could create or amplify diseases. We already see the effects of invasive species on our own eco-system in the U.S. and also our food supply so it will only get worse. The use of pesticides will also contribute because they are killing the beneficial insects that feed off pests.

Thank you very much Dragonflykingdom for your valuable response. Yes you are correct, above mentioned factors affecting the reproduction, distribution and survival of pest is the prime reason that augment population and proliferation of pests. In terms of destruction made by them not only to human health but likewise to food industry will be the worst dilemma. Thus, ridding them out will be the best and effective move to deter spread out nuisance, destruction and diseases to people and environment. However, using pesticide and insecticide to control pest is ideal and recommended especially nowadays. It will not affect beneficial or harmless insects if the applicator is properly educated on the correct procedure of treatment application and the proper handling of chemicals.
