Molecular Ecology Resources, Volume 22, Issue 5, Page 1706-1724, July 2022., 2022 Abstract Management of agricultural pests requires an understanding of pest species diversity, their interactions with beneficial insects and spatial‐temporal patterns of pest abundance. Invasive and agriculturally important insect pests can build up very high populations, especially in cropping landscapes.

First report of Sri Lankan cassava mosaic virus and Cassava Mosaic Disease in Laos.
Plant disease, 2021 Cassava (Manihot esculenta Crantz) has been traditionally grown as a subsistence crop in Laos, but in recent years cassava cultivation in this country has expanded and is becoming a 'cash crop' for farmers (Malik et al., 2020). This also means that cassava vegetative seed (stakes) is rapidly multiplied and distributed.

Structural Analyses of AC4 Protein of Sri Lankan Cassava Mosaic Virus
International Letters of Natural Sciences, 2015 RNA silencing is one of the important phenomenon in plant defense mechanism, it actively protect host plants against viral infections. Existing viruses must have developed counter defense strategies to survive this arms race. Such counter defense strategy is the viral silencing suppressor (VSRs) which have been reported to directly interfere with the ...
