Moldova Technologies Entomophagous Trichogramma for Biological Plant Protection of the Agricultural Crops Against Pests
Entomophagous Trichogramma for Biological Plant Protection of the Agricultural Crops Against Pests
Description
One of the most important biological agents in Plant Protection is Trichogramma (useful insect) which is used against different pests in integrated plant protection. Rearing of Trichogramma on moth eggs increases the biological indexes and its efficacy in the field.
Trichogramma evanescens W. reared on preliminarily irradiated moth eggs, has been used for different crops: corn, cabbage, peas, tomatoes combating noctuid pest complex, and Trichogramma embryophagum H. - against apple worm in the orchards.
Innovative Aspect and Main Advantages
During the rearing process of the continuous mass production of Trichogramma the biological indexes such as prolificacy, percentage of females, number of total individuals, migration capacity diminish and as a result the biological efficacy decreases. With the scope of increasing the Trichogramma efficacy in the field, several technologies have been developed.
Among new technologies, one of the most fundamental is the rearing process in laboratory conditions of the Trichogramma on preliminary irradiated moth eggs (Sitotraga Cerealella O.) which leads by 2 or 3 times higher biological indexes compared to initial prototypes (rearing of Trichogramma on non irradiated moth eggs). This result leads by 15 to 20% higher biological efficacy in the field and consecutively by a 15 to 20% more yield. The moth eggs irradiated production and Trichogramma production processes are factors that contribute to a higher productivity (by 20- 25%), lower costs (by 1,5 times) compared to Trichogramma prototypes – reared on non irradiated eggs and compared to chemical pesticides (by 3 to 4 times).
