The 'Cake on the plate' syndrome ... and how specialist tansy aphids avoid extinction by hungry predators and parasitoids: insights from the use of polymorphic microsatellite markers
(2016-07)
It was initially shown from 12.2 m high suction trap aerial density data and later confirmed using polymorphic molecular markers (initially allozymes, later high resolution DNA markers, especially microsatellites), that ...
Stay at home aphids: comparative spatial and seasonal metapopulation structure and dynamics of two specialist tansy aphid species studied using microsatellite markers
(2011-06)
Two tansy-feeding aphids, Macrosiphoniella tanacetaria (MA) and Metopeurum fuscoviride (ME), were studied at a
small spatial scale in and around Jena (< 80 km2) using polymorphic microsatellite markers. Both species were ...
Effects of pea aphid secondary endosymbionts on aphid resistance and development of the aphid parasitoid Aphidius ervi: a correlative study
(2010-05)
In order to reduce parasite-induced mortality, hosts may be involved in mutualistic interactions in
which the partner contributes to resistance against the parasite. The pea aphid, Acyrthosiphon pisum
Harris (Hemiptera: ...
Drought Response in Selected Tropical Inbred Maize Lines and Relative Expression of PARP2 Gene under Limited Water Conditions
(Science Publishing Group, 2018-04)
Drought is the leading single factor that limits maize production thus inhibiting the crops genetic potential. In
response to drought, maize and other plants synthesize Poly ADP-Ribose (PAR) protein. This process is ...
Spatial population dynamics of a specialist aphid parasitoid, Lysiphlebus hirticornis Mackauer (Hymenoptera: Braconidae: Aphidiinae): evidence for philopatry and restricted dispersal
(2010-01)
Within insect communities, the population ecology of organisms
representing higher trophic levels, for example, hymenopterous
parasitoids, may be influenced by the structure of
their insect hosts. Using microsatellite ...
Field Abundance Patterns and Odor-Mediated Host Choice by Clover Seed Weevils, Apion fulvipes and Apion trifolii (Coleoptera: Apionidae)
(2015-02)
The clover seed weevils Apion fulvipes Geoffroy, 1785 and Apion trifolii L., 1768
(Coleoptera: Apionidae) cause major losses to seed production of white clover (Trifolium repens L.) and
red clover (Trifolium pratense ...
Mating Strategies in Solitary Aphid Parasitoids: Effect of Patch Residence Time and Ant Attendance
(2011-06)
Mate finding and dispersal from the natal patch in parasitoid Hymenoptera
are influenced by the availability of host resources and interactions with other
organisms. We compared the mating behavior of three solitary aphid ...
Food algae for Lesser Flamingos: a stocktaking
(Springer, 2016-07)
Lesser Flamingo, the flagship species of saline wetlands of Africa and India, is a specialised feeder subsisting on microscopic cyanobacteria and algae. To establish the relationship between flamingo occurrence and food ...
Plant parasitic nematode assemblages associated with sweet potato in Kenya and their relationship with environmental variables
(Springer, 2016-11)
Sweet potato is one of the most important staple food crops consumed in Kenya and throughout Africa but yields are greatly reduced by plant parasitic nematodes (PPN). The aim of this study was to determine the prevalence ...
Diversity and Abundance Patterns of Amphibians in Rehabilitated Quarries of Bamburi Near Mombasa (Kenya)
(Research, 2013-11)
Amphibians are sensitive to changes in the environment and are, therefore, excellent
indicators of success in restoring degraded habitats. As such, a clear understanding on how
amphibian populations respond to changes ...
