12 protostelid (microscopic slime mold) species were found in 15 samples of aquatic and terrestrial litter taken from northeast German ponds, 90% of species (including all of the most common) being found in both types of litter. Terrestrial litter contained more protostelids (14% of cultures) than aquatic litter (12%), and the water column contained none.

When tomatoes were inoculated with the fungal endophyte Acremonium strictum, only 20% of Cotton Bollworm caterpillars survived to adulthood, compared to 54.5% on uninoculated tomatoes, although they still ate the same quantity of leaves.

Cotton Bollworm – Helicoverpa armigera

The invasive Japanese knotweed has 180 natural arthropod enemies; the sap-sucking jumping plant louse Aphalara itadori may be the first authorised for use in the European Union. 146,885 A. itadori eggs were laid, and it took 33 days to go through 5 nymph stages at 23oC. 1.52% of eggs laid on 87 species or varieties of plants were not on Japanese knotweed, but these did not become adults. When nymphs were transferred to Maidenhair vine, 7% developed to adulthood.

Japanese knotweed – Fallopia japonica
Maidenhair vine – Meuhlenbeckia complexa
