Existing wild rose pests can freely migrate around the site, affecting other horticultural crops. The wild rose pests and control described in the article will help the beginning grower to arm themselves with useful knowledge and resist the onslaught of insects. Very often there are various sawflies, who literally destroy the shrub, sucking all the sap from its branches. The bush can not fully develop and gain green mass.
Caterpillars on the dog rose are another huge problem, since it is rather difficult to notice the years of butterflies before laying eggs. Usually they do their black work at sunrise or after sunset. Florist sees only the consequences of this spectacle in the form of various caterpillars, gnawing leaves and flower buds. Treatment of invasions with chemicals allows you to quickly reduce the population and save the shrub.
Look at the wild rose pests in the photo, where various individuals are shown during the periods of the larval stage and subsequent phases of development:
Rosan sawflies: control measures and pest photo
Rosan sawflies are common pests of this crop. See their varieties. Presents images of insects and measures to combat them.
Green Sawthrow Allantus basalis Kl. - an insect having two pairs of membranous wings with a clearly visible venation. The larva is green, without a pattern, has 8 pairs of abdominal legs, the head is red-brown with a black or brown spot on the back of the head. The larvae feed on roses and wild roses, eating leaves from the edges and eating holes.
Control measures with pink sawfly include the destruction of individual pests. With a large number of spraying one of the drugs: fufanon, Kemifos, Aktellik, Kinmiks, Spark, Inta-Vir, given the waiting time.
See how rosy sawflies look like - the photo shows heterosexual individuals and larvae.
Sawfly rosacea mucous.
Rosy slimy sawfly Caliroa aethiops F. (syn. Endelomyia aethiops F.) - insect length 4-5 mm, with two pairs of membranous wings, body black, middle legs whitish. Wings are blackish, pterostigma black-brown. The larva is yellowish, the back is green, covered with mucus, has 8 pairs of abdominal legs, the head is reddish with black eyes and two brown spots. The last segment of the body with transverse rows of spinous warts. The feeding and development of the larvae occurs on rosehip leaves from late June until autumn, after which they go to the soil and pupate in an earthen cocoon. One generation is developing annually.
Control measures with a pink sawfly of this type are the same as against the green type of pest.
These pests of roses and the fight against them are shown in the photo in the form of different individuals and agrotechnical procedures:

Aphid green rose Macrosiphum rosae l. - the small sucking insect is green, sometimes brown in color, 2-3 long, mm, with a long xeroid tail. Ducts and antennae long, black. Insects feed on the sap of young leaf tissues, shoots, and buds, causing their deformation. With a large number of aphids, the damaged parts of plants are covered with secretions of the pest, having the form of a sticky liquid. Eggs overwinter on the shoots near the buds, the larvae emerge in the spring and damage first the buds and then the growing leaves. During the summer, up to seven generations develop, and numerous pest colonies form on the shoots.
Often damaged buds are not disclosed and dry up. Winged female settlers constantly fly over to neighboring plants and form new colonies.
Control measures. Preventive spraying of bushes before flowering and, if necessary, in the summer with one of the preparations: fufanon, kemifos, actellik, kinmiks, spark, aktar, fitoverm, Inta-Vir.
Aphid rose cereal Metapolophium dirho dum Walk. - small sucking insect length 2-3 mm, light green color with a dark longitudinal stripe on the back. It feeds from the lower side of the leaf blade and with a large number causes yellowing and curling of the edges of young leaves.

At first they feed on dandelion, tulips, irises, then on flowering fruit and berry crops, and then again on flower ones. Females lay eggs in the soil, from which white curved larvae with a brown head and six legs hatch.
Larvae feed on plant debris and small roots of plants. In autumn, the larvae pupate, beetles emerge from the pupae, which remain to winter in the soil. The beetle lives on humus-rich soils, where it constantly increases the number and damages many flower and fruit crops.
Control measures. Collection and destruction of beetles, selection of larvae when loosening and digging the soil.

How to treat wild rose from pests of walnut poppy
Before treating wild rose from these pests, it is worth finding out that the nut-pots are small, up to 4 mm long, with insects with webbed wings. In June, females lay eggs under the bark of shoots and leaf epidermis, as well as in flowers. Soon the larvae hatch and begin to feed on tissue sap. As a result of feeding the larvae, characteristic growths are formed - galls of various colors and shapes. According to the shape of the galls, it is possible to determine the type of nut-popper that damages the plant. After feeding, the larvae hibernate in the galls, pupate in the spring, and at the end of May-June adult insects fly out.

Seeds become fusiform, 5-8 long mm. Over time, the gall turns brown and dries out. Monochrome walnut Rh. centifoliae Hart, causes the formation of small spherical single-chamber, the size of a pea galls on the underside of the leaves. The galls are greenish-red, turning brown with time.
Rosaceae nutcracker, or begegoir Rh. rosae l., causes the formation of large (from 5 to 50 mm) spherical multi-chamber reddish-green galls covered with dense processes. Over time, they harden and turn brown. They are located singly or severally at the ends of the shoots, on the leaves, sepals and rosehip petals.
Smooth walnut Rh. eglanteriae hart, causes the formation of small spherical multi-chamber galls on the upper side of leaves attached at one point. May also be on the leaf stalks, on the bark and thorns of the shoots. Nutcracker Spiny Rhodites spinosissimae Gir. causes the formation of multi-chamber oval smooth double-sided galls with small spikes 3-15 mm in length. Located on the central vein, petioles, fruits.
Myra nutcracker Rh. mayri schlecht. The galls are round or oblong, often irregular in shape, up to 22 mm in length, in large clusters in the same place and with numerous small spikes.
Prickly Nut Rhodites rosarum gir. causes the formation of light green with a red spherical, with occasional thick spikes of galls from the underside of the leaves of the hips.
Control measures. Pruning and destruction of the Gauls in the fall or early May, before the departure of insects. Preventive spraying of plants in the spring of one of the drugs: fufanon, kemifos, actellik, kinmiks, spark, Inta-Vir.

How to spray dogrose from small caterpillars: how to get rid of pests
Before you get rid of the caterpillars on the dog rose, you should know that rosehip seed Megastigmus asuleatus Swed. - small insect length 2,6-3,8 mm.
