-
Study on taxonomy, biology, morpho- and ecophysiology of plant
pests and diseases and their natural antagonists.

Grant 4092 Morphological, electrophysiological and behavioural
bases of prey searching in ground beetles (Coleoptera, Carabidae)
(2000-2003)
| Leader: Enno Merivee |
-
Establishment of the typology, numbers, and distribution patterns of antennal
sensilla in some ground beetles having potential plant protectional importance
and/or different search behaviour.
-
Explanation with electrophysiological experiments food and conspecific
beetles’ odours (aggregation and sex pheromones) olfactory effect on the
antennal chemoreceptors of various ground beetles.
-
Explanation with behavioural tests, if and how (anemotaxis, chemotaxis,
chemokinesis) food and conspecific beetles’ odours effect the searching
behaviour of the ground betles being studied.

Establishment of species composition and abundance of predatory arthropods
especially carabids in different crops.
-
Estimation of the influence of field size and margins to carabid
abundace.

Grant 4116 Comparison of intensive and ecological farming: its impact
on the biodiversity in Estonia (2000 –2003)
| Leader: Marika Mänd |
-
Comparing ecological and conventional farming for assessment
their impact on biodiversity: estimation of pollinators abundance,
their species diversity and foraging strategy in ecological and conventional
farms.
-
The influence of landscape structure to the pollinators.
