Distribution, abundance, population ratios and acoustic behaviour of conocephalus maculatus (orthoptera: tettigoniidae) in Kagera region North-Western Tanzania
A thesis submitted in partial fulfillment of the requirements for the award of degree of Master of Science (Animal Ecology) in the School of Pure and Applied Sciences of Kenyatta University
Rapid phenotyping for identification of rice resistant varieties to Diopsis apicalis (Diptera: Diopsidae) Westwood
TLDR
Nineteen rice varieties were assessed against D. apicalis, under partially controlled environment in a screen-covered cage at AfricaRice-Benin, showing the importance of shade and humidity in the biology of diopsids and finding 20 and 30 couples of insects per square meter were the best for an efficient screening.
Abundance, distribution and effects of temperature and humidity on arthropod fauna in different rice ecosystems in Uganda
The study is on abundance, distribution and effects of temperature and humidity on arthropod fauna was conducted in smallholder rice farming areas in three agro ecological zones of Lake Victoria
Diopsids (Diopsis thoracica and D. apicalis) Damaging Rice Production in Africa: A Review
TLDR
Breeding showed a transmissibility of this resistance to the progenies as NERICA4, and research has shown the influence of climatic factors and alternative hosts in the expansion of these pests.
International Journal of Current Research in
Diopsids are pests responsible for significant losses in rice and other cereal crop production. Damages resulting from this attack particularly during tillering and flowering stage are fatal.
Insect Vectors of Rice Yellow Mottle Virus
TLDR
About forty insect species were identified as vectors of RYMV since 1970 up to now, essentially the beetles, grasshoppers, and the leafhoppers; the chronology of their identification was presented.
Biological Control of African Rice Gall Midge (Orseolia oryzivora, Harris and Gagné) in Nigeria: A Review
African rice gall midge (AfRGM),Orseolia oryzivoraHarris and GagnE(Diptera: Ceccidomyiidae) is a serious insect pest of lowland rice in Africa ,and is capable of causing total crop failure in endemic
Effects of thermal stress on the brown planthopper Nilaparvata lugens (Stal)
TLDR
Overall, sub-lethal heat stress extended egg development time, inhibited nymphal development, lowered fecundity and reduced feeding activity, and that acclimation over a generation compared with a single life stage increases tolerance across the thermal spectrum.
Influence of Cropping and Irrigation Systems on Population Fluctuation of the African White Rice Stem Borer (Maliarpha separatella Rag) and Damage on Rice
TLDR
It is demonstrated that irrigation methods and cropping systems greatly influence fluctuation of M. separatella infestation and suggests that in case of double cropping it will be necessary to control the stem borer and efforts should be made to ensure that farmers synchronize planting dates.
Evaluation of Damage Induced by Aspavia armigera Fabricius on Different Rice (Oryza sativa Linn.) Varieties
TLDR
At 2 bugs per peduncle caused a significant reduction in rice yield parameters in both upland and lowland varieties and is therefore the damage threshold for the varieties tested.
