The orientation of the wasp within the host pupa is the same as that of the leaf miner itself, the head of the wasp [...] appearance of Dacnusa sibirica The life cycle of Dacnusa sibirica consists of an egg, a larva, a pupa and an adult. In order to see the eggs and larvae of the [...] jaws. The larvae of the parasitic wasp only reaches full development after pupation of the leaf miner larva. The adult parasitic wasps emerge from the leaf

Absorption of fixed and non-fixed nutrients: Trichoderma [...] known for its ability to promote plant growth, enhance plant health , and suppress plant diseases. Trichoderma harzianum colonizes the root systems and s [...] metabolic processes. Strengthening the plant: Trichoderma harzianum improves the root system through the formation of more root hairs, so that water and

False spider mites

Most species that cause damage to cultivated plants belong to the genera Brevipalpus and Tenuipalpus . The most common species [...] misshapen, presumably because the mites secrete a substance while feeding, that is poisonous to the plant. In places where mites have been feeding, collapsed

Mealybugs and scales

In order to gain an adequate intake of protein, mealybugs must ingest large quantities of sap, getting rid of the excess sugars in the form of honeydew [...] honeydew, which, as well as the white, waxy secretion of the mealybugs, reduces the ornamental value of the affected plants. Fruit and flowers are also [...] (mealybugs). They suck the sap of plants and are mostly host plant specific. Apart from the damage they cause by sucking plant sap, mealybugs and soft

Koppert believes [...] giving you the ability to recognize the pest or disease you are up against by means of detailed illustrations and close-up photographs. The knowledge gained [...] photographs, and dozens of illustrations of the most prevalent pests, diseases and their natural enemies. This book provides the reader with the necessary information

Various factors, such [...] vibrations, aiding in the transfer of pollen. Within one to four hours, the bumblebee's jaw imprints on the flower, commonly known as bite marks, turn brown [...] occur before the flower closes. The duration of flower openness varies between one to three days, depending on environmental conditions. To evaluate pollination

Sciarid flies

General Sciarid flies constitute the family of Sciaridae. The species that cause most damage to crops belong to the genera Bradysia and Lycoriella . Lycoriella [...] damage is the immediate result of larvae feeding on the roots. The larvae feed mainly on decaying plant material and on algae and fungi present in the soil [...] flies The life cycle of sciarid flies has the following stages: egg, four larval instars, a pupal instar, and the adult. The adult insects are 1 to 5 mm

The pathogen grows into the stem and on the plant surface and new sporangiophores (structures containing sporangia, a type of spores) [...] above-ground plant parts, leaf wetness is required. Dispersal is by wind and rain causes the pathogen to be returned to the soil from infected plants. Dispersal

Trianum-G

Trianum-G grows around the mycelia of the pathogens. The cell walls of the pathogens break down and the pathogens die.
