Planococcus citri or mealy bug | ملی بگ کو کیسے کنٹرول کیا جائے
Morphology and Identification Mealy bugs are small, sap-sucking insects that belong to the family Pseudococcidae. They are pests that affect a wide range of plants, including agricultural crops, ornamental plants, and houseplants. Here are the key characteristics to identify mealy bugs Appearance Body: Mealy bugs have soft, oval-shaped bodies covered with a white, powdery or waxy substance, giving them a cottony or mealy appearance. This wax coating helps protect them from desiccation and predators. Size: Adult females typically measure between 1 to 4 millimeters in length, depending on the species. Color: They are generally white or light gray, but some species may have a pinkish or yellowish hue. Life Stages: Eggs: Female mealy bugs lay eggs in clusters, usually hidden under their bodies or in crevices of the plant. The eggs are enclosed in a waxy, cotton-like sac. Nymphs: After hatching, the nymphs (crawlers) are mobile and disperse to find feeding sites. They resemble smaller versions of the adults but lack the thick waxy covering. Adults: Adult females remain wingless and continue to feed on plant sap, while adult males, which are rarely seen, have wings and do not feed. Male mealy bugs exist primarily to mate with females. Impact on Plants Mealy bugs are serious pests that can cause extensive damage to plants: Feeding Damage: Sap Extraction: Mealy bugs use their piercing-sucking mouthparts to extract sap from the plant s phloem. This weakens the plant, leading to yellowing leaves, stunted growth, and in severe cases, plant death. Sooty Mold: As they feed, mealy bugs excrete honeydew, a sticky substance that attracts ants and promotes the growth of sooty mold. This black fungal growth can further inhibit photosynthesis and reduce plant vigor. Transmission of Plant Diseases: Viruses: Some mealy bug species are known vectors of plant viruses, which can spread diseases that further compromise plant health. Economic Impact: Agricultural Losses: Mealy bugs can infes . :::: میرا یوٹیوب چینل دیکھیں @ Botany Knowledge ( [ 🔗 کلک‼️ ]] )
