Abstract:

The study of degree attack of H armigera

was performed at VRDS Bacau during 2010-

2012.

The attack appeared at end of June in all

years.

Attack level in first generation of pest was

very low, therefore go unnoticed. There were no

significant differences between the three variants

during 2010 - 2012.

In second generation of H. armigera the

degree of attack (DA%) was under 1,3% in open

field at Unibac and Roma cultivar. In tunnels

DA% was high: 8,9% in 2010, 4,5% in 2011 and

14,5% in 2012. Climatic conditions were very

favorable for pests in 2012: drought and high

temperatures, so that may be a reason why the

attack was very high in tomatoes grown in the

tunnels.

In tunnel the attack in pepper ranged

between 0,9 % in 2010, 3,8 in 2011 and 5,0 % in

2012.

The attack of tomato fruitworm in bean

was high in 2012 in Auria Bacaului variety. The

pest attack of second generation increased

progressively in the three years of study, being:

1,1 in 2010, 2,1 in 2011 and 5,7 in 2012.

The data obtained show that H. armigera

population is increasing. In order to prevent the

damages produced by this pest a continuous

monitoring of its population must be performed.

This pest is polyphagous insect and it can attack

many species of vegetable.

Keywords:

monitoring, tomato fruitworm, vegetables.
