Rhyparida(Sumathra Spiny Leaf Beetle
A Spiny Silent Beast on the move......Spotted a Spiny Leaf Beatle in Mangalore, Karnataka this evening. It mostly strives on Grasslands and Paddy Fields. I happened to notice it and took the click...After clicking, did a research and came to know that this is the Spiny Leaf Beetle...
It scrapes the upper surface of leaf blades leaving only the lower epidermis. It also tunnels through the leaf tissues. When damage is severe, plants become less vigorous. The presence of grassy weeds in and near rice fields as alternate hosts harbor and encourage the pest to develop. Heavily fertilized field also encourages the damage. Heavy rains, especially in premonsoon or earliest monsoon periods, followed by abnormally low precipitation, minimum day-night temperature differential for a number of days, and high RH are favorable for the insect’s abundance.The Spiny Leaf Beetle is common in rainfed and irrigated wetland environments and is more abundant during the rainy season.
