Annotations of novel antennae-expressed genes in male Glossina morsitans morsitans tsetse flies
Bwana, Billiah K.; Mireji, Paul O.; Obiero, George F.; Gakii, Consolata; Akoth, Modesta O.; Mugweru, Julius N.; Nyabuga, Franklin N.; Wachira, Benson M.; Bateta, Rosemary; Ng’ang’a, Margaret M.; Hassanali, Ahmed (Plos 1, 2022-08)Tsetse flies use antennal expressed genes to navigate their environment. While most canonical genes associated with chemoreception are annotated, potential gaps with important antennal genes are uncharacterized in Glossina ... -
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
Nyabuga, Franklin N.; Loxdale, Hugh D.; Weisser, Wolfgang W. (2008)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 ... -

Nyabuga, Franklin N.; Loxdale, Hugh D.; Heckel, David G.; Weisser, Wolfgang W. (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 ... -

Molander, Mikael A.; Winde, Inis B.; Burman, Joseph; Nyabuga, Franklin N.; Lindblom, Tobias U. T.; Hanks, Lawrence M.; Millar, Jocelyn G.; Larsson, Mattias C. (Springer, 2019-06)Longhorn beetles are ecologically important insects in forest ecosystems as decomposers of woody substrates, microhabitat engineers, and as components of forest food webs. These species can be greatly affected both ... -
Effects of pea aphid secondary endosymbionts on aphid resistance and development of the aphid parasitoid Aphidius ervi: a correlative study
Nyabuga, Franklin N.; Outreman, Yannick; Jean-Christophe, Simon; Heckel, David G.; Weisser, Wolfgang W. (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: ... -

Impact of low-cost management techniques on population dynamics of plant-parasitic nematodes in sweet potato
Maina, Hellen; Karuri, Hannah W.; Rotich, Felix; Nyabuga, Franklin N. (Elsevier, 2020-07)Sweet potato is an important food security crop but its production is limited by various biotic constraints including plant-parasitic nematodes (PPN). In Kenya, current PPN management practices in sweet potato have several ... -
Mating Strategies in Solitary Aphid Parasitoids: Effect of Patch Residence Time and Ant Attendance
Nyabuga, Franklin N.; Völkl, Wolfgang; Schwörer, Ulrich; Weisser, Wolfgang W.; Mackauer, Manfred (Springer, 2012-01)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 ... -
