Abstract:
The bird's – foot trefoil is one of the most important fourage plants
after the lucerne and trefoil. Its importance consists firstly in the fact that is a
leguminous plant with the biggest adaptability at the weather and soil
conditions but also at the pests and disease attack. In the production case of
the bird's – foot trefoil seed, one of the insects that produces the greatest
damages, about 80% from the total production, is the bird's – foot trefoil
thrips. Even if it was mentioned in the special literature from the country and
abroad, that pest was studied a little and that because this paper proposed to
emphasize some experimental data concerning of its biology.For the
investigations accomplishing in the years 2004-2006, the experimental field
was placed at Didactical Station Timisoara. The experiences location was
realized after the standard method of the experiences location, in three
repetitions, each parcel with a length of 2m and a latitude of 1m. In realizing
the biometrical measurements it built an insulators with metallic skeleton and
covered with gauze.For studying the bird's – foot trefoil thrips biology, the
samples taking were accomplished during a period of 20 days, from 20 June
to 10 July 2006, with a periodicity of taking at each 48 hours. After the
biometrical measurements it established that the length of adults body of
Odontothrips loti Hal. was of 1,5195+-0,176777mm.The length of cephalic
capsule and pronote were of 0,4415+-0,044413mm. The cephalic capsule
length was of 0,13975mm+-0,042802mm. The cephalic capsule latitude was
of 0,331mm+-0,041304mm
