Rice Long-shoulder and Long-shoulder Acerola
The scientific names of this species are *Clketus trigonus* (Thunberg) and *C. pugnator*, both belonging to the family Hemipteridae. These insects are commonly found in regions such as the Yangtze River Valley, as well as in provinces like Jiangsu, Henan, Yunnan, and Guizhou. They primarily feed on a variety of plants including rice, amaranth, thorn wide, lotus seed grass, earth nepeta, straw grapes, corn, and soybeans. This makes them a significant pest in agricultural areas where these crops are cultivated. In terms of damage, nymphs feed by sucking sap from rice plants or damaging grass berries, which can lead to stunted growth and reduced yields. Their feeding activity can cause visible symptoms such as yellowing leaves and weakened plant structures. Morphologically, the adult long-shouldered spiny bug has a body length of 7.5–8.8 mm and a width of 4–5 mm. The antennae segments 1–3 are dark brown and equal in length, while segment 4 is dark brown with a reddish tip. The front half of the pronotum is lighter in color, and the lateral angles extend outward as spines without being upturned. Clear white spots are present in the inner corners of the black leather flaps. The scutellum is coarse, and the base segments of the fore and mid legs each have two small black spots. The body color is light, with four dark spots on the abdomen and two smaller or less noticeable spots in the middle. The eggs are initially white, turning yellowish and translucent over time. The last-instar nymphs are tan and brown, with small black lines on the back of the abdomen. The lateral angles of the anterior thoracic plate extend outward into needle-like structures, and the wing buds reach the posterior edge of the third abdominal segment. The short-shouldered spiny bugs are similar in appearance but have shorter frontal and thoracic spines, with the width between the side angles less than half the body length, making them distinguishable from their long-shouldered counterparts. In terms of life habits, this species typically completes 2–3 generations per year in the Yangtze River Basin. Adults survive the winter in leaf litter or dried grass clumps and begin laying eggs between March and April of the following year. Eggs are usually laid on leaves, ears, or stems of host plants. For prevention and control, it is recommended to follow the same methods used for managing the rice spine bug. These may include cultural practices such as crop rotation, maintaining proper field hygiene, and using insecticides when necessary. Monitoring populations and applying targeted treatments can help reduce infestations and protect crop yields effectively.
