The mites [...] lay their eggs mainly on the underside of the leaf or on the fruit surface. The elongated, oval eggs are firmly attached to the surface and are rather large [...] (about 0.07 mm) compared with the subsequent, active stages. They are transparent and speckled with white dots.

The female lays up to 2,000 eggs on the underside of the leaves of their host plant, usually separately but sometimes [...] brownish green, sometimes with a black lateral line. The body has stiff hairs and is usually greenish with a light lateral line. Below the lateral line there

The ants will clean and protect the coccids and in turn benefit from a rich food source. The honeydew also quickly becomes [...] can cover the leaves, flowers and fruit of the host and reduce photosynthesis and respiration. Life cycle and appearance of Brown soft scale The scale of

• Oleander scale

  Scale infestation can be seen by the appearance of the scale armour on stems, leaves and fruits of hosts. Infestations on the leaves and stems may cause wilting [...] colour, round in shape, with a scale whose apex is off-centred. This scale resembles a miniature fried egg with a diameter of 2 mm. The newly hatched crawlers [...] quickly attach themselves to the plant and form a scale. Colonies mainly form on the underside of leaves. After 1 to 2 months, the female reaches adulthood

• Mycotal in Salad Crops

  hyphae that penetrate the insect’s epicuticle before entering the inner tissues, where it rapidly proliferates, causing death of the target pest. Salad crop [...] contact with the target pests; select spray nozzles giving a droplet size range of 50-100 µm; angle spray nozzles to achieve good penetration of the canopy [...] Environmental conditions: the development of Mycotal is favoured by high relative humidity (above 70%, when applied with the adjuvant Addit ) and temperatures

• Tomato leaf miner

The larva crawls into the ground to pupate [...] leaving the outer layers of the leaf and stalk intact. Shortly before pupating, the grown larva cuts a sickle-shaped exit hole in the leaf with its mouth [...] percentage of the larvae remain hanging on the leaf and pupate there, sometimes on the upper surface but more commonly on the underside.

The eggs elongate [...] General The garden chafer ( Phyllopertha horticola ) is a beetle from the Scarabaeidae family. It does most of its damage in the larval stage when it feeds [...] feeds on roots of grasses and clover. The adults feed on the leaves of trees like oak, hazelnut and birch and on the flowers and developing fruits of, for

The damage [...] are mostly found along the veins on the underside of leaves. The mites are flattened and egg-shaped when seen from above, with their dorsal surface showing [...] of the plant. In some crops, plants can become misshapen, presumably because the mites secrete a substance while feeding, that is poisonous to the plant

The other species [...] Fusarium oxysporum is the species causing vascular wilt. First the leaves turn yellow and wilt, mostly on one side of the plant. Finally, the whole plant wilts [...] brown discolouration of the xylem vessels which can be seen when the stems are cut. In banana, whole plantations may die and the soil may not be suitable
