Main pests of red meat and pomelo

<

In our county, red spider infestations occur throughout the year. Affected leaves show numerous dense white spots, leading to chlorosis and loss of luster. Severe infestation causes leaf drop. The adults are nearly oval and dark red in color. Red spiders have a wintering period from February to March, with the first peak occurring between late April and late June. A low peak appears during July and August due to cooler temperatures. From mid-September to November, dry weather leads to a second peak. Timely control during the first peak can significantly reduce population density, minimizing the need for repeated sprays. For control, it's essential to apply pesticides at key times. In early February, spray Karmant 2000 times. From late April to mid-May, use pyridazinone 2000 times or day sweep 2500 times. From mid-June to late January, apply Karmant 3000 times. A single spray in mid-September with Karmant 3000 times is also effective. If the pest population is low, reduce the concentration to 3500 times. After fruit harvest in mid-November, if red spider density is high, spray 1500 times. If infestation is light, spraying may be avoided, and a mixture of rosin can be used later in December for additional control. Rust spider, also known as rust wall, is one of the most common and damaging pests in our county’s grapefruit regions. It often leads to garden decline due to improper control. The fruit develops damaged oil cells, resulting in dark brown, smaller, sour fruits. Leaves and fruit initially appear dusty, later turning reddish. Pericarp wounds become susceptible to "strickle," and severe damage causes leaf fall, weakening tree vigor and affecting yield for two years. Prevention should begin in early May, early June, late July, and late August, using 80% zinc sesquioxide 500 times or water ampholytic 1000 times. Other insecticides may be added for better results. Aphids are major pests in young shoots during spring, summer, and autumn. They cause curling of new shoots, excrete honeydew that leads to sooty mold, and spread viruses like Huanglong disease. Control involves spraying 50% malathion 700 times or 80% dichlorvos 1000 times, applying 1–2 times per shoot length of 0.5–5 cm. Leafhoppers are prevalent in nurseries and saplings, affecting young shoots of mature trees less severely. Damage occurs from May to September, causing leaf miners and ulcers. Spraying every 5–7 days, 0.5 cm from the tip, with 3–4 applications total. Chemicals such as chrysanthemum oil 3000 times, Kezibao 1500–2000 times, and methomyl 2000–2500 times are recommended. Swallow butterflies have about five generations per year. Adults emerge after warm springs, lay eggs on young leaves, and larvae feed on leaves. Control involves 80% dichlorvos 1000 times or dipterex 800 times. Fruit borers (Hey) are serious pests that cause fruit drop or shrinkage. Adults emerge in mid-November, laying eggs from March to April. Control involves spraying 50% malathion 700 times or 80% dichlorvos 800 times during nymph stages. Bridge insects have three generations annually. Larvae feed inside the canopy, and control involves Trichlorfon 800 times or pine EC 500 ml. Scarabs are common in mountainous orchards, feeding on young leaves, flowers, and fruits. Control uses foliar sprays of 1000 times liquid or 80% dichlorvos 1000 times. Tianniu (bark beetles) live in trunks and emerge in April–May. Adults mate and lay eggs on trunks. Control includes capturing adults, scraping eggs, and injecting insecticides into wormholes. Scale insects include brown round worms, sharp tips, wax whiteflies, and blowing cotton. Each has different life cycles and control methods. General control involves Karmant 1000 times, aqueous ammonia phosphor 1000 times, malathion 100 times, or double acenaphthene 700 times. Pine oil mixtures are especially effective in winter, eroding wax and reducing pests like locusts, red spiders, and sooty mold.
