    High tunnel melon and watermelon production
    (University of Missouri--Columbia. Extension Division, 2026) Cabrera-Garcia, Juan
    "Many warm-season (frost-sensitive) vegetable crops can be grown in a high tunnel. Cucurbits are a large, diverse group of warm-season plants in the Cucurbitaceae family. Cucurbits include many popular vegetables such as cucumber, cantaloupe (muskmelon), squash, pumpkin, watermelon and gourd. Most are an important dietary source of fiber, minerals, beta-carotene and vitamin C." -- first page

    Dairy grazing : growth of pasture plants
    (University of Missouri--Columbia. Extension Division, 2026) Kallenbach, Robert L.
    "Understanding how plants function (physiology) and their form and structure (morphology) is important when managing grazing animals because both physiological and morphological changes affect plant survival and the quantity and quality of forage. An awareness of how plants respond physiologically and morphologically to their environment provides the basis for understanding how plants react to external factors such as high and low temperatures, drought, light and grazing." -- first page

    "Thrips (Thysanoptera: Thripidae) are small (1/16 inch long) elongated insects that can be a serious insect pest of high tunnel melons and watermelons. Thrips are usually found clustered in flowers and on the underside of leaves, especially near the terminal growth of the vines. Damage to the plants is caused by adult and nymph thrips scraping the surface of the leaves with their mouthparts and feeding on the exuding sap. The damaged plants will have small, silver streaks on the leaves, and the plant looks as though it has been sandblasted (Figure22). Fruit can have surface scars from early-season thrips feeding. Thrips, like aphids, can be imported into the high tunnel on transplants." -- first page

    "Greenhouse whitefly (Trialeurodes vaporariorum (Westwood)) is the most common whitefly species that can infest high tunnel melons and watermelons. Whiteflies are small (1/16 inch long),soft-bodied insects with wings covered with white, powdery wax." -- first page

    "Spider mites are small (1/50 inch long), oval-shaped arthropods related to spiders. The most common spider mite on high tunnel melons and watermelons is the two-spotted spider mite (Tetranychus urticae) with two dark spots on the abdomen (Figure 21). Mites can be found on the underside of leaves where they congregate and suck sap from the plant. The leaf surface develops a scratch-like, "strippled" appearance and interveinal yellowing or bronzing develops (Figure21). Eventually the leaves die, and the plant becomes progressively weakened. As the population of mites increases, they develop a webbing around the area where they feed and lay eggs. Mites thrive in hot, dry climates (at least 80 degrees Fahrenheit and less than50 percent relative humidity) and thus become a problem on high tunnel melons and watermelons from midseason onward in the Midwest." -- first page
