Future perspective of Ground beetles.
Ground beetles are not harmful to the human (it might be possible they if they are mishandled they might pinch you at your skin) neither they are injurious to clothing,food or buildings they are nuisance only if they are found indoors ,they do not reproduce when they are indoors.
The response of beetles to Global Warming.
It is indicated by the Meterological records that there is a increase in the global warming since last century .Oceans have also got warm due to increase in the temperature during the last 40 years being detected in pacific ,Indian ,and Atlantic oceans to the depth of 3000 m, with the largest amount of warming,0.3 celsius, in the upper 300m (levitus et al.,200).
Effects of the global warming have been recorded on both of the polar regions .Beetles have survived in the past because of their small size ,population dynamics ,and their ability to disperse .In future , beetles will respond to climate chance by dispersal .Certainly the beetles would adapt genetically to difference in dinual and seasonal temperatures and to the day light.
One of the quaternary fossil beetle record is that species extinction is not associated with the climate change .The rate of extinction would be greater in future than in past .the reason is that natural habitats have become increasingly fragmented by human activites.
Global warming potentially makes a bad situation even more pathetic .For many species, dispersal will mean abandoning the security of patches of natural habitat for disturbed areas where they will probably to more vulnerable to predators ,to disease, and to being poisoned by pesticide remaining in the soil and by chemicals ingested from genetically altered crops. Some individuals take this next to their next generation or natural habitat (lovejoy,1997).
In many of cases of any of us gets encountered by a minor number of ground beetles indoors.The one of the necessary control is physical removal ,e.g capture them in a container or remove them with a vaccum.
We can also try setting out sticky traps ,such as those used for cockroaches.Place these traps in areas where ground beetles are most commonly found,especially along walls.
If we encounter a large number of ground beetles ,we can reduce their amounts by some of non-chemical steps:
Seal and repair entry points such as cracks in the foundations ,gaps and spaces around doors,ground level windows and similar areas.
Thin out or remove wood mulch or other organic mulch that is directly adjacent to the foundation.
Stack firewood away from the home as far as is practical.
Remove stones,leaves,boards,and other nearby debris.
Cut or remove tall grass and weeds around the home.
Minimize the use of lights from bright white to yellow to minimize attracting ground beetles.
Few ground beetles such as carabid species play a vital role in agricultural systems by predating crops or feeding on the seeds of weeds .Such forms of natural biocontrol are important when considering future strategies for food production. There is considerable interest for example ,reducing dependence on pesticides by boosting predatory insects abundance using non-crop field margins.
Use of Insectides
Insecticides are not necessary applied if the number is minor but if the number of ground beetles gets higher inside the buildings or in harvested areas then a n insecticide treatment around exterior of the particular area is an option .An appliance of the insecticides around the foundation is helpful in reducing the number of ground beetles that may enter buildings or cropy areas.
Common examples include products that have active ingredients like ,bifenthrin ,cyfluthrin, deltamethrin and premethrin purchased as liquid reay-to-use or occasionally as granular ready-to-use.
