Information about the life cycle of your garden foe can go a long way in helping to address the problem. It is necessary that the edge with grass worms because these small creatures can have all their roots of plants are eaten before you know it. They dig into the ground and, unless you know where to look for them – and when – they will destroy all your garden plants.
A meal of grass is larvae of a beetle. Turf worms eventually turn into beetles (European chafer or Japanese beetles are two examples). Grass worms have their home on the ground and feed on the roots of their plant. Therefore, you do not always realize that they are there or have damaged your plants until the worst is done.
The life cycle frame or growth time of the larvae of an adult beetle extends to one year: from June to June. The last part of the month of June or the beginning of July of the first year is the term that Japanese adult beetles emerge from houses on the ground in search of a couple and something to eat. Beetles can fly up to a mile away to feed if they want, preferring lime, roses or grapes. Other beetles choose plants that are not ornamental, therefore they are less noticed.
During the month of July, female beetles return to the land to lay their eggs. This is a process of two to three weeks and networks of approximately 60 eggs. The eggs hatch approximately two weeks later. Once hatched, the future beetle is considered a first-stage meal and eats grass roots for most of the month of August. Its second and third stages, which occur between the end of August and October, continue to grow and now eat plant roots, including turf. The coldest climate that drives them down into the ground, where they spend the winter until early spring, when they return to the top floor to eat plant roots again. At the end of spring they stop eating and turn into beetles in late June or early July.
Prevention / Solution
The best time for gardeners to get rid of grass worms and limit damage to the roots is during their most vulnerable period: after hatching. The successful control of large populations of grass worms should be addressed during this first stage of development, the use of biological and chemical insecticides.
Knowing the prisoner life cycles is key to knowing when to wait to hatch on your floor, if you have them. It is also important to calibrate when to try to control them with insecticides for the greatest success. And that knowledge helps gardeners protect their roses and other ornamental plants as well.
