Allelopathy on selected major crops. Many crop cultivars show strong allelopathic properties, of which rice ("Oryza sativa") has been most studied. Rice allelopathy depends on variety and origin: Japonica rice is more allelopathic than Indica and Japonica-Indica hybrid. More recently, critical review on rice allelopathy and the possibility for weed management reported that allelopathic characteristics in rice are quantitatively inherited and several allelopathy-involved traits have been identified. Many invasive plant species interfere with native plants through allelopathy. A famous case of purported allelopathy is in desert shrubs. One of the most widely known early examples was "Salvia leucophylla", because it was
Mythimna separata light dorsal stripe, with black-brown lateral stripe along spiracle line. spiracles brown with black rim. Pupae are yellowish brown and shiny. The moth flies from January to April depending on the location. The larvae feed on a range of agricultural plants like "Zea mays", "Sorghum bicolor" and "Oryza sativa" and are thus considered a pest. Caterpillars do not feed on "Momordica charantia" due to the presence of the triterpenoid glucoside called momordicine II, which is a natural inhibitor of caterpillar actions. China experiences periodic outbreaks of northern armyworm infestation. The outbreak in 2012 was particularly severe. Larva can be hand
