Coevolutionary fine-tuning: evidence for genetic tracking between a specialist wasp parasitoid and its aphid host in a dual metapopulation interaction
(Cambridge University Press, 2012-04)
In the interaction between two ecologically-associated species, the population structure of one species may affect the population structure of the other. Here, we examine the population structures of the aphid Metopeurum ...
A survey of root knot nematodes and resistance to Meloidogyne incognita in sweet potato varieties from Kenyan fields
(Elsevier, 2016-11)
The root knot nematode, Meloidogyne is one of the most economically damaging plant parasitic nematode
groups, and are widely distributed in Kenyan agro-ecosystems. The aim of this study was to
determine the diversity of ...
Bacteria and Archaea diversity within the hot springs of Lake Magadi and Little Magadi in Kenya
(2016-07)
Background: Lake Magadi and little Magadi are hypersaline, alkaline lakes situated in the southern part of Kenyan
Rift Valley. Solutes are supplied mainly by a series of alkaline hot springs with temperatures as high as ...
Isolation and characterization of some gut microbial symbionts from fungus-cultivating termites (Macrotermes and Odontotermes spp.)
(2016-07)
Microbiota of termites is crucial for nitrogen cycle activities and degradation of recalcitrant components
of plant biomass that influence soil structure and carbon mineralization in tropical and subtropical
regions. The ...
Temporal genetic structuring of a specialist parasitoid, Lysiphlebus hirticornis Mackauer (Hymenoptera: Braconidae) attacking a specialist aphid on tansy
(2010-11)
In insect species characterized by inbreeding, limited dispersal, and a metapopulation structure, high genetic
differentiation and reduced genetic diversity within local populations are expected. Using the model ...
Coevolutionary fine-tuning: evidence for genetic tracking between a specialist wasp parasitoid and its aphid host in a dual metapopulation interaction
(2012-09)
In the interaction between two ecologically-associated species, the population
structure of one species may affect the population structure of the other. Here, we
examine the population structures of the aphid Metopeurum ...
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: ...
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 ...
