There are two types of mealybugs: armored and soft. Both form colored bumps on the stems, leaves and fruits of plants.

They also feed by sucking the sap of plants and produce molasses. An infected tree can produce large amounts of molasses that falls and covers the objects underneath with a sticky film that attracts ants, flies, wasps and bees.

Summer pests: caterpillars

There are many different species of caterpillars, but they all do the same damage … chewed leaves and flowers, appear as one of the summer pests, especially if there has been a lot of rain.

The beginning of the plague of the caterpillar, usually comes given by some eggs (placed by the female in adult status) on the underside of the leaves, especially those of the lowest part of the plant, the closest to the ground. As soon as the egg hatches, the first samples of the pest appear.

One of the best control methods is to spray the plants with Bt. (Bt is a biological control, basically a bacterium that mixes with water) With this remedy what is achieved is that the caterpillar feeds on this bacterium, which dies in a few days.
