effects of bacillus thuringiensis δ endotoxins on the pea aphid Acyrthosiphon pisum
Applied and Environmental Microbiology, 2009Co-Authors: Manuel Porcar, Brian A. Federici, Anne-marie Grenier, Yvan RahbéAbstract:Four Bacillus thuringiensis δ-endotoxins, Cry3A, Cry4Aa, Cry11Aa, and Cyt1Aa, were found to exhibit low to moderate toxicity on the pea aphid, Acyrthosiphon pisum, in terms both of mortality and growth rate. Cry1Ab was essentially nontoxic except at high rates. To demonstrate these effects, we had to use exhaustive buffer-based controls.

Applied and environmental microbiology, 2009Co-Authors: Manuel Porcar, Brian A. Federici, Anne-marie Grenier, Yvan RahbéAbstract:Four Bacillus thuringiensis delta-endotoxins, Cry3A, Cry4Aa, Cry11Aa, and Cyt1Aa, were found to exhibit low to moderate toxicity on the pea aphid, Acyrthosiphon pisum, in terms both of mortality and growth rate. Cry1Ab was essentially nontoxic except at high rates. To demonstrate these effects, we had to use exhaustive buffer-based controls.

Genome Analysis of "Candidatus Regiella insecticola" Strain TUt, Facultative Bacterial Symbiont of the Pea Aphid Acyrthosiphon pisum.
Microbiology resource announcements, 2020Co-Authors: Naruo Nikoh, Ryuichi Koga, Masahira Hattori, Kenshiro Oshima, Tsutomu Tsuchida, Takema FukatsuAbstract:ABSTRACT The genome of “Candidatus Regiella insecticola” strain TUt, a facultative bacterial symbiont of the pea aphid Acyrthosiphon pisum, was analyzed. We determined a 2.5-Mb draft genome consisting of 14 contigs; this will contribute to the understanding of the symbiont, which underpins various ecologically adaptive traits of the host insect.

genome sequence of candidatus serratia symbiotica strain is a facultative bacterial symbiont of the pea aphid Acyrthosiphon pisum
Microbiology resource announcements, 2019Co-Authors: Naruo Nikoh, Ryuichi Koga, Masahira Hattori, Takema Fukatsu, Kenshiro OshimaAbstract:ABSTRACT “Candidatus Serratia symbiotica” is a facultative bacterial symbiont of aphids that affects various ecological traits of the host insects. Here, we report the complete genome sequence of “Candidatus Serratia symbiotica” strain IS, consisting of a 2,736,352-bp chromosome and an 82,605-bp plasmid, from the pea aphid Acyrthosiphon pisum.

role of host nutrition in symbiont regulation impact of dietary nitrogen on proliferation of obligate and facultative bacterial endosymbionts of the pea aphid Acyrthosiphon pisum
Applied and Environmental Microbiology, 2007Co-Authors: T L Wilkinson, Ryuichi Koga, Takema FukatsuAbstract:The impact of host nutrition on symbiont regulation in the pea aphid Acyrthosiphon pisum was investigated. The population density of the obligate symbiont Buchnera aphidicola positively correlated with dietary nitrogen levels. In contrast, the population density of the facultative symbiont Serratia symbiotica increased in aphids reared on low-nitrogen diets, indicating distinct regulatory mechanisms in the same insect host.

host plant specialization governed by facultative symbiont
Science, 2004Co-Authors: Tsutomu Tsuchida, Ryuichi Koga, Takema FukatsuAbstract:In North America and Europe, the pea aphid ( Acyrthosiphon pisum ) encompasses ecologically and genetically distinct host races, offering a model system for studies on sympatric speciation ([ 1 ][1], [ 2 ][2]). One host race lives on red clover ( Trifolium pratense ) and cannot produce offspring on

Short Communication: Occurrence of the pea aphid, Acyrthosiphon pisum (Harris) (Homoptera: Aphididae) on wild leguminous plants in West Gojam, Ethiopia
Sinet Ethiopian Journal of Science, 2004Co-Authors: Melaku Wale, Bekele Jembere, Emiru SeyoumAbstract:The occurrence of pea aphid, Acyrthosiphon pisum (Harris) (Homoptera: Aphididae), on wild annual and perennial leguminous plants was studied at two locations (Adet and Wondata) in West Gojam, Ethiopia in 1999/2000 seasons. Annual and perennial leguminous wild or volunteer plants encountered in the study areas were closely monitored for the presence of pea aphid. The results showed that pea aphids infested annual legumes such as clover ( Trifolium ruepellainum ) (wild) and vetch ( Vicia spp) carried more aphid load than clover. The aphid attacked more vetch in September and clover in October. From perennial legumes, pigeon pea ( Cajanus cajan ) was the most susceptible to attack by pea aphids and it was heavily infested and damaged in September and October. High plant density of vetch carried more aphid load than low plant density; sole stand of vetch plants suffered more damage than when grown mixed up with other crops or weeds suggesting the advantage of intercropping to reduce pea aphids.
