The Corn Rootworm - Virtually Everywhere!


North, South, and West: we usually thought them as only the cardinal directions, but they are these directions also lend their name to 3 different kinds of a distinctive beetle referred to as the corn rootworm! Well-known for feeding exclusively on corn crops, they are mostly found in America, predominantly in the condition of Iowa, the region's largest corn maker.

One of the primary misconceptions about these creatures may be the fact that they feed only on corn throughout their lifetime, thereby destroying mature crops and leading to huge amounts of damage. What's interesting to find out maybe the fact that both the Northern and Western species tend to feed much less on corn and even more on the pollen and plants of other vegetation as the corn will mature. Though of program, the corn crop continues to be affected, but possibly the effect isn't as pronounced as we are informed. In case the rootworm matures before the corn crop, the adults will keep the corn only and tend to feed only on the leaves rather. This information pays to since farmers can take notice of the life-cycle of the corn rootworm and plant their crops in a fashion that ensures they'll grow before the adults can emerge! Certainly, most farmers take part in crop rotation because of this very reason.

The corn rootworms are extremely small creatures - very much like the majority of beetles - with the adults being only 25 % of an inch very long. The differences between your Western and Northern species are quite pronounced though; the former tend to become yellowish with an individual dark stripe on each wing cover, as the latter differ between solid color tones of light tan to pale green. In any case, the beetles are fairly simple to identify, provided you can observe them!

Like beetles like the Emerald Ash Borer, the corn rootworm life-routine also depends greatly on the positioning the egg is laid in, along with the temperature of the spot. The eggs lay by the female are extremely minute - just 0.1 millimeters long - and so are shaped like an American football. Preferring colder temps to develop in, the eggs are usually deposited in the winters, roughly 8 millimeters beneath the soil. In some instances, this depth can boost depending on how dried out the soil is usually, and also how if it's colder than the normal temperature to be able to create a much better insulating coating around the small eggs. The men are quicker to emerge compared to the females, but both genders are completely thriving in the weeks of July and August when the temps are warmer and conducive to feeding. The emergence of the adults proceeds for nearly a month from enough time it begins, which is an extremely long period for such a little creature!

People often tend to overlook how fascinating these creatures could be because they're too busy researching to prevent them. However, there is much more to them than meets the attention. Only 1 question remains though: will there be an Eastern corn rootworm species to total all of the compass directions?
