Abstract:
The present study has been
conducted under a bilateral project between
Romania and Republic of Moldova,
focusing on knowledge of the invertebrates
from rape (Brassica napus L.) and alfalfa
crops (Medicago sativa L.) from Singureni
(Giurgiu County, Southern Romania). The
communities structure of invertebrates fauna
in term of species composition and
numerical abundance were analyzed. In
total, 15 species of Collembola from seven
families and 38 species of Coleoptera from
17 families were identified. Entomobrya
handschini, Lepidocyrtus paradoxus,
Isotoma anglicana were abundant in the
alfalfa crop and Hemisotoma thermophyla,
Protaphorura sakatoi, Orchesella
flavescens (Collembola) were abundant in
the rape culture. From Coleoptera Order,
Dermestes murinus, Brachinus crepitans
and Epicometis hirta were dominant in the
rape crop. Coccinella septempunctata and
Gonioctena fornicata were dominant in the
alfalfa. Also, another 385 specimens from
different taxonomic groups (Heteroptera,
Homoptera, Diptera, Hymenoptera,
Thysanoptera, Orthoptera and Araneae)
were collected using sweep nets. Some crop
pests invertebrates were indicated and the
beneficial predators were also revealed.
