Host plants include representatives of the Malvaceae (okra and cotton), Alliaceae (onion), Fabaceae (peanut, cowpea, pea, bean, soybean, alfalfa and chickpea), Anacardiaceae (mango) Moraceae (fig), Apiaceae (carrot and fennel), Begoniaceae (begonia), Amaranthaceae (spinach), Cucurbitaceae (watermelon, cucumber, squash and pumpkin), Caricaceae (papaya), Brassicaceae (mustard greens, raddish, cabbage, broccoli, cauliflower, kale, brussel sprouts, and turnips), Solanaceae (tomato, eggplant, potato, tobacco bell pepper and chili pepper), Asteraceae (chrysanthemum, lettuce and sunflower), Rutaceae (lemon), Rosaceae (apple and peach), Poaceae (corn, wheat, rice and sugarcane), Rubiaceae (coffee), Musaceae (banana), Zingiberaceae (ginger) and Convolvulaceae (sweet potato and common morning glory). |
