As a result they immediately [...] release and don’t needs to get energy from spider mite from the field to develop the eggs. This will increase the population in your crop. Proof of predation

• Chafers

  fly in the evening, generally in June and July and land on trees to mate. During the night the females move to the ground to lay their eggs. Eggs are shiny [...] with a yellow-brown head, and up to 30 mm long when fully grown. Larval development takes two years, fully fed larvae pupate in an earthen cell and the adult

• Bacterial wilt, brown rot

When conditions are less conducive for disease development, the plants may show signs of stunting and produce many adventitious roots [...] water. Disease incidence is highest when soil moisture is high, such as during rainy periods. When temperature is low, infection may remain latent until

Research & Development Will Continue PGRO, Pherosyn and Koppert will continue their work to develop other legume pest monitoring tools [...] combining peas are occasionally attacked. The larvae feed in the flower buds during June, leading to flower failure and significantly reduced yields in the
