Abstract:

The studies were carried out over the year

2010 in a 18 years old cherry tree orchard, at S.C.

Fructex S.A. Bacau. The invertebrates

communities of the epigean fauna in 2010 include

species belonging to 8 classes, 12 orders and 22

families with an amount of 7083 individuals. The

Insect class is about 55.88% of the whole

collected material. According to the relative

abundance of the trophic categories, we can say

that the structure of the invertebrates communities

of the epigean fauna is well-balanced, the

ecosystem is stable, due to the age of the cherry

tree culture and on the other hand due to the lack

of the chemical treatment. The study of the

canopy insect pests highlighted two categories of

insect pests: endophagous species, especially

leafmining insects and ectophagous species,

respectively aphids and ectophagous insect

larvae. However, even if the frequency of attack

of both endophagous and ectophagous species has

recorded high values, we found that the intensity

of attacks did not reach pest economic threshold.

Keywords:
