epa killerhidro, como va eso? how is everything? hope all is good 
here is a little info, more info here http://www.ext.colostate.edu/PUBS/INSECT/05536.html

*Grasshoppers are the most difficult insect to control because they are highly mobile.
*All grasshoppers lay their eggs in soil.
*There are over 100 species of grasshoppers in Colorado.
*During periods when local outbreaks are developing, control usually involves using sprays or baits.
Grasshopper Control
Natural Controls
The most important factors are weather related, particularly around the time of egg hatch. For example, cold, wet weather is very destructive to newly hatched grasshoppers. However, very dry winter and spring conditions also can be harmful to survival since required tender new plant growth is not available.
Some insects commonly feed on grasshoppers. Many species of blister beetles (see fact sheet 5.524, Blister Beetles in Forage Crops) develop on grasshopper egg pods and blister beetle abundance cycles along with their grasshopper hosts. Adult robber flies are common predators of grasshoppers during summer and other flies develop as internal parasites of grasshoppers. Many birds, notably horned larks and kestrals, feed heavily on grasshoppers. Grasshoppers are also frequently eaten by coyotes.
Grasshoppers are also subject to some unusual diseases. A fungus (Entomophthora grylli) infects grasshoppers causing them to move upwards and cling to plants shortly before they kill the insect host. Stiff, dead grasshoppers found stuck to a grass stem or twig indicate infection with this disease. A very large nematode (Mermis nigriscens) also sometimes develops in grasshoppers. Both the fungus disease and nematode parasite are favored by wet weather.
Managing Grasshoppers with Baits and Sprays
During periods when a local outbreak develops, control usually involves using sprays or baits. To be successful these need to be applied to developing stages of grasshoppers and concentrated at sites where egg laying occurs. Ability to control grasshoppers declines as grasshoppers develop and migrate.
Surveys of grasshoppers can be very useful in anticipating problems and treating appropriately. Numbers of grasshoppers present in late summer and early fall can be a good indicator of problems the subsequent year. Follow-up surveys the following spring to detect young nymphs can determine when eggs have hatched. Area-wide surveys may locate egg beds and other sites where early season activity originates.
Treatments should be directed at the young grasshoppers and nearby vegetation present in these breeding sites. At lower altitudes, this often occurs in May; early June may be the optimal time for grasshoppers at higher elevations. Sprays of insecticides are most effective at this time and several insecticides are effective
Insecticide options are greater for larger acreages and unit costs are less expensive. The addition of canola oil to insecticide sprays can improve control by making treated foliage more attractive to feeding grasshoppers.
Alternately, baits containing carbaryl (Sevin) can be broadcast. Bait formulations are made by mixing the insecticide with bran or some other carrier and kill grasshoppers that feed on the bait. These treatments limit application effects on other insects present in the treated area. However, availability of Sevin baits is frequently limited, or prohibitively priced for use on large areas. Baits must be reapplied after rain.
Insecticide treatments do not need to completely cover the area since grasshoppers are mobile. Insecticides applied as bands covering 50 percent of the area, or even less, have proved very effective for control of grasshoppers in rangelands. Backpack sprayers and application equipment modified for use on ATVs can be used in larger acreages. A review of this method, known as Reduced Area Acreage Treatments (RAATS) has been prepared by the University of Wyoming at: www.sdvc.uwyo.edu/grasshopper/atvraats.htm.
Where grasshoppers develop over large areas and impact several properties, coordinated area-wide control is very useful. As this requires some additional preparations in planning, early surveys are even more important. Grasshopper control often is much more successful as a community effort.
Once grasshoppers have reached the adult stage and migrations occur, some insecticides may be applied directly to plants. Such applications have only short effectiveness and damage can occur before individual grasshoppers are killed. Furthermore, the choice of insecticides is more limited since few allow direct application to garden fruit and vegetables.
Nosema locustae Baits
Baits containing the protozoan Nosema locustae is a biological control option that may be considered for treating grasshopper breeding sites. This is sold under the trade names NOLO Bait or Semaspore and can produce infection of many species of grasshoppers. Because it is selective in effects, only affecting grasshoppers, its use is sometimes considered desirable.
There are some limitations to Nosema locustae baits. Only young grasshoppers are susceptible, and it can not be used effectively after adult migrations have occurred. It is also fairly slow acting and does not equally infect all grasshopper species. Often it is most effectively used in a long-term grasshopper management program, in combination with other controls.
Nosema locustae baits are also perishable. They are best kept refrigerated before use. Expiration dates are usually printed on packages and should be checked.
Other Controls
If insecticides are not used, some protection of a garden may be possible by watering grasshopper breeding areas to promote plant growth. This may retard migrations of grasshoppers to areas of more desirable plants. Mowing or other activities that deny food plants in breeding sites should be avoided.
Susceptible plants may be protected by screening or cheesecloth barriers. However, grasshoppers can chew through most fabrics.
Repellents do not appear to be effective. Some materials used as repellents, such as vegetable oils and garlic-based preparations, may instead increase grasshopper feeding on plants.
Poultry may feed heavily on grasshoppers. Turkeys, guinea hens, and chickens have all been used to help control grasshoppers. However, garden areas may need to be fenced since scratching by chickens can be harmful to young plants."
