The most common pests of indoor plants

Spider mites

Red spider mite Tetranychus cinnabarinus - refers to a group of serious pests of nearly all houseplants.epoxy coatings |

Adult ticks are very small - female 0,5 mm, males - 0,3 mm. Females purple-red, bright red males. Reproduction of mites increases with increasing temperature. In red flat mite is distributed as ordinary spider mite Tetranychus urticae and the Atlantic spider mite Tetranychus atlanticus.premium jerky |

Ticks live on the top and underside of leaves, on shoots on the branches, and when the mass reproduction and the fetus. Damaged plants have pale-yellow color. Between the leaves and stems of plants there is a thin transparent web. The surface of the damaged leaves at first covered with pale spots on the exhaustion of the cell sap, but further increases the spot and form a solid whitish spots, leaves fall prematurely. The plant is weakened, laid bare, fruits decreases. Contribute defeat spider mites dry air in the room. Ticks are dangerous by the fact that under adverse conditions, the females burrow into the soil or hiding places (cracks in pots, under leaves, etc.) and fall into a state called diapause. At this point, all the vital processes of ticks inhibited (as if he becomes dormant). When the enabling environment mites emerging from diapause and begin to grow and multiply. Therefore, the main preventive measure is to maintain optimum conditions for plant growth and especially the high humidity. Also for reasons of preventing the appearance of Spider mites, it is necessary to strip the old dead leaves, remove withered flowers from time to wash the plant with a damp sponge or to arrange a warm shower (if the plant does not tolerate such procedures, carefully cleaned with a soft brush).

Control measures. If infected plants are not strong, then you can first try to fight the pest, carefully wiping the leaves on both sides of the stems and soapy water. In more severe defeat by spraying insecticide - neoron, fitoverm, Fufaev, agravertin, aktellik, sulfur).

Flat pliers

Or simply ploskotelki - very small mites, body length from 0,25 to 0,4 mm. The body of the mite egg-shaped, yellow or brick red. The most common red flat mite (or orange flat mite) Brevipalpus obovatus, as well as Cactus Flat mite Brevipalpus russulus. They are known as pests of cacti, citrus, euonymus, figs, Aucuba and other houseplants. These very small pests are very difficult to detect, in addition, they do not form a web. Symptoms of these pests are slowly wilting leaves, and eventually death of the plant. Danger mites are flat and that at normal room temperature of 18 to 24 ° C, they are able to reproduce throughout the year.

Control measures. Rubbing soap solution may not yield positive results, so it is better to use insecticide spraying - fitoverm, Fufaev, aktellik, neoron, karate, sulfur.

Briobii

These include Briobiya festucae Bryobia graminum, and Clover mite Bryobia praetiosa. Briobiyu cereal difficult to see on the plant, although it is not such a small size is about 0,8 - 1 mm in length. Her body was reddish, broad, in shape, with long legs. Briobiya festucae very mobile and quickly moved around the plant. Lay big orange eggs along the veins on the upper side of the sheet. Clover mite smaller sizes - up to 0,6 mm, has an oval body is brown or green. Lays on the leaves of spherical dark-red eggs. Symptoms of these pests are white or yellowish spots-strokes that appear on the surface of the leaf epidermis of leaves mertveet and cracks, the leaves are deformed and twisted. Injury had briobiyami very similar to the defeat of TRIPS, but unlike the last briobii leave eggs on the upper side. Despite the fact that briobii not so frequent pests, they can harm houseplants, penetrating into the house from the street or hitting the plants of the summer in the garden.

Control measures. If infected plants are not strong, then the first can be carefully wiped with a soap solution on both sides of the leaves and stems. In more severe defeat by spraying insecticide - neoron, fitoverm, Fufaev, agravertin, aktellik).

Root mites

These include several different types of mites, which combines the fact that they damage underground parts of plants. Among the root mites are more common bulbous root mite Rhizoglyphus echinopus and bulb mite Steneotarsonemus. These mites hurt the first bulbs (gladiolus, hyacinths, tulips, orchids and other) mites are very small dimensions - bulbous root mite about 0,5 - 1 mm wide oval body is light yellow in color, narrowed to an end, and four pairs of legs. Bulb mite slightly larger - up to 1,5 mm in length, has an oval body and two pairs of legs. They gnaw tissue bulbs, laying there eggs in large numbers - about 300 eggs per female mite bulbous root. Thus the initial stage lesions seen eaten places and passages mites, but gradually mites gnaw whole onion. Defective bulb is easy to fall apart in the hands or breaks, it shall leave all the internal tissue, there is only white trash, and mites can not see the aided eye. Root mites reproduce and develop in a wide range of temperatures - from 10 to 25 ° C and even higher when conditions change, they do not die and fall into a state of diapause. Root mites especially strong breed with high humidity. Therefore, one of the measures to prevent emergence of mites is to store the root tubers, bulbs and tubers in a cool, dry room, with a moisture content no higher than 60%.

Control measures. Before landing, carefully inspect the bulb. Promotes the emergence of the root mites conditions of increased soil moisture. You do not need watering less than it needs, it is necessary to prevent stagnation of water in the roots, ie do good drainage and drain water from the pan. Affected bulbs and plant roots watered stand or systemic insecticide solution (eg, neoron, aktellik, Apollo).

Tsiklamenovy mites

Tsiklamenovy mite Phytonemus pallidus - is a microscopic mite, a body length of about 100-300 microns, has an oval yellowish translucent body with four pairs of legs. Tsiklamenovy mite resettled mainly on the lower side. In a large cluster look like a layer of dust. Most striking cyclamen, balsam, pelargonium and Saintpaulia. In infected plants the leaf margins are rolled, twisted stems, buds wither. Contribute defeat tsiklamenovogo mites humidity. Characteristic feature is also a increase in pubescence on petioles and leaves of Saintpaulia.

Control measures. Remove all affected leaves, flowers and buds. Spraying of conventional insecticides give a bad effect, you can use spray.

Trips

Harm the adult insects and larvae. The body of an adult thrips 1-1,5 mm, narrow, elongated, flat. Trips black or brown, with yellow, reddish belly. Two pairs of wings. In larvae of the yellow body. Females lay a sheet of pulp is light, transparent eggs. Development from egg to adult insect is 20-30 days. The photo shows the flower Saintpaulia, damaged by thrips, Thrips themselves are very small, like little black dots on the leaves. The main factor contributing to the reproduction of thrips, is a high temperature and low humidity. At room conditions thrips can injure the year round, but especially in spring and summer.

Process damage mainly to the leaves. At the bottom of the sheet thrips lays numerous colonies, and on the upper side of the sheet appear bright points. As a result, the upper side of the leaf is gray-brown with a silvery sheen. When the entire surface of mass destruction leaves become whitish and discolored, then the leaves turn brown and fall off. Thrips cause major damage to flowers, which are covered in spots and deformed.

In addition, TRIPS contaminate plant their black sticky secretions, which settles sooty mold. There are many kinds of pests such as thrips Dratsenovy Parthenothrips dracaenae, Rosanna TRIPS Trips fuscipennis, flower thrips Hercinothris femoralis, onion thrips Liothrips vaneeckei, and other types, but does not make sense to establish species belonging TRIPS, as they all have common characteristics and measures to combat them are the same.

Control measures. As prevention of the emergence of TRIPS is to maintain a sufficiently high humidity around the plants, the regular inspection of all plants. It is also very effective against thrips tape traps for flying insects. Plant should be sprayed, if necessary, repeated insecticide (fitoverm, decis, aktellik, Inta-sup, karbofos, agravertin, see drugs)
