Apple, Blueberry and Cherry Maggots
Most of us love fruits because we consider fruit to be very healthy. Insects also consider the same thing since they feed on some fruits for survival. Fruit flies are usually seen coming out from the soil. The Cherry maggot usually comes out during the first week of the month of June and the Apple Maggot and blueberry maggot are seen coming out on the months of July. The female maggots undergo certain stage before they proceed into mating stage and laying eggs follow. When the maggots lay eggs they usually feed on the honeydew of the plans and some leaves extracts to help them and also for their eggs to develop well. There are some traps placed by some fruit growers, they call it yellow sticky traps so that the flies that goes near the fruits won’t harm the fruit they are infesting. These traps sometimes possess the scent of the aphid honeydew so more insects are being drawn to it. It is advised that the traps should be cleaned weekly. They also said that the Apple maggots provide great damage during summer time until the harvest period, in preventing apple maggots to attack use field-microscopes to detect the eggs after the mating period. The use of trap is the best option as mentioned in this article and it has proven to have 95 percent effectiveness in controlling apple maggots. (more…)

Management of Insects in Forage Crops

Alfalfa is one of the most important crops in the United States and a lot of producers grow Alfalfa for its agriculture benefits. However, there are insects affecting the growth of Alfalfa; these insects are alfalfa weevil, alfalfa snout beetle and the potato leafhopper; these insects are viewed by the producers under field-microscopes. The presence of alfalfa weevil and alfalfa snout beetle is visible before the first crop cutting and the potato leafhopper appears after the crop’s first cutting. These insects usually go back to the fields during springtime so that they can lay eggs in alfalfa plants, this can be prevented though, eggs are very small and they are not usually visible by our naked eyes so we need field-microscopes to check the presence of eggs on every stem of the alfalfa plants.
The alfalfa plant and the weevil both enjoy springtime, it is usually during the spring when they lay eggs more. After a certain stage they call larval development the alfalfa weevil creates a spider web like cocoon on the plant itself, sometimes on the dead leaves and mostly on the plant stem. This can be visibly seen but if you want to view how the cocoon was weaved, field-microscopes can help you see more. After a week or so, the adult weevil will come out of the cocoon and feed on the plant for another period of time. The alfalfa weevil undergo some resting period, feed, and lay more eggs but since they can only live through one generation each year most the eggs they produce can’t survive until winter. (more…)

Shoot Boring Insects

Many different kinds of insects feed in the shoots of pine trees. Some insects, such as the white pine weevil, can severely damage the growth, form or appearance of trees. Other insects, such as the pitch nodule maker, rarely cause serious damage. Still other insects, like the pine shoot beetle, may cause infested trees to be regulated by state or federal restrictions on shipping. (more…)

Lawn Insects

In this study, the two kinds of insects were discussed, the beneficial and the harmful insects. It was emphasized that not all the damage on residential lawns are caused by insects. The use of insecticides on lawn is sometimes unnecessary and has proven to be causing damage than benefits on the lawn. The ill effects of insecticides are not visibly seen at the present but will prove to be very inconvenient to the homeowners later on.
Both beneficial and harmful insects can be viewed under field microscopes and can also be identified accordingly. (more…)

Field microscopes are portable microscopes. These devices are the more lightweight and compact, compared to the traditional microscopes. These are used whenever researchers go out on the field and to their studies. (more…)

Special Features of a Quality Field Microscope

For microscope enthusiasts, a field microscope is the one to use whenever they are out in expeditions and nature research. Field microscopes are often those used in country locations, simply because they can withstand any type of weather. It may be too hot or too cold but field microscopes wouldn’t get its name ‘field’ for nothing. (more…)

A Practical Buying Guide for Mini Field Microscopes

admin — Wed, 22 Aug 2007 09:16:01 +0000

Mini field microscopes are often used by many researchers and scientists in a wide range of industries and applications. These instruments are commonly found used during field work involving natural and geological scientists, biologists, medical and health science researchers and even crime scene investigators. More recently, mini field microscopes have also begun to grow in popularity with many students and hobbyists, primarily because they are more flexible and sturdier than standard laboratory microscopes. If you’re planning on purchasing a mini field microscope any time soon, here is a short guide on what to look for and why: (more…)

Common Sense Tips on Using a Field Microscope

Field microscopes are compact, portable optical microscopy. These are built as lighter versions of most standard microscopes but are designed to be durable and sturdy, to make the instrument easy to carry, transport and use during field studies. Although they are smaller, field microscopes have the same functionality as traditional microscopes. Here are a few simple steps on how to use a basic field microscope: (more…)

Care and Handling Tips for Field Microscopes

A field microscope is the type of microscopy used for field work. Standard laboratory type microscopes are not always ideal for use outdoors because they are often not sturdy enough. Field microscopes, which are lighter and more compact, are built to withstand the tough handling that characterizes field work. However, they should also be handled and cared for like every other sensitive instrument. Here are some important handling tips necessary to keep your field microscope in top shape: (more…)
