Geosmin is a common, musty-smelling sesquiterpene, principally produced by cyanobacteria. Anabaena ucrainica (Schhorb.) Watanabe, a water bloom-forming cyanobacterium, is the geosmin producer responsible for odor problems in Dianchi and Erhai lakes in China. In this study, the geosmin synthase gene (geo) of A. ucrainica and its flanking regions were identified and cloned by polymerase chain rea...

We examined 35 species of ground and epiphytic lichens, including fruticose, foliose, crustose lichen, as habitats oribatid mites. Observations were carried out in the taiga forests northeast European Russia, 87 from 38 families found. The Crotoniidae, Carabodidae, Oppiidae, Suctobelbidae are most numerous lichens Oribatulidae epiphytes. Micreremidae Licneremaeidae only noted A complex characte...

Coccinellids are important biological control agents and aphid predators in horticultural crops around the world. Neotropical Cycloneda sanguinea, Eriopis connexa Coleomegilla quadrifasciata octodecimpustulata, exotic Harmonia axyridis (all Coleoptera: Coccinellidae), that mainly feed on aphids. In this work we described abundance of these coccinellid species their spatial temporal cooccurrence...

AbstractThe coccinellids Eriopis connexa (Germar), Harmonia axyridis (Pallas) and Olla v-nigrum (Mulsant) are important natural biological control agents. The purpose of this paper was to study the biology and create a fertility life table of these three coccinellid species. For the biology study, 50 insects/species were used and kept in groups of 10 in glass vials (2300cm3). For the three spec...
