Spider mites are small plant-feeding arachnids rather than insects. On mango foliage, feeding can cause stippling, bronzing, or declining leaf quality, sometimes with fine webbing when populations are high. Dust, plant stress, and disruption of natural enemies can affect outbreaks. Inspect leaf undersides with magnification if possible and distinguish pest mites from predatory mites. A pale or dry-looking leaf is not enough for diagnosis, and routine broad insecticide use can sometimes worsen mite problems by removing beneficial predators.
Spongy tissue is an internal mango quality disorder in which part of the flesh develops an abnormal, often pale or corky texture instead of normal ripening. It may be hidden beneath a reasonably normal peel. The term describes the tissue condition and is not proof of a particular pathogen or a single cause in every cultivar. Assess maturity, temperature history, and the distribution of affected fruit, and avoid presenting extra fertilizer or an unverified spray as a guaranteed cure.
Stem-end rot is decay that begins around the stalk attachment of harvested fruit and may extend into the flesh during ripening. Several fungi can be involved in mangoes, including species associated with latent infections and wounded tissue. Sound-looking fruit at harvest can therefore develop symptoms later. Gentle handling, appropriate sanitation, and suitable storage help reduce losses, but the name alone does not identify the exact organism. Do not confuse normal sap staining with progressive soft decay around the stem.
The stigma is the receptive surface of a flower's female reproductive structure where pollen can land and begin the process leading to fertilization. In a mango's bisexual flower, its condition and receptivity are part of successful reproduction. Seeing pollen on a flower does not prove that a compatible pollen tube has reached an ovule. The term is useful when understanding pollination, but ordinary growers usually gain more from protecting flower health and insect visitors than from attempting to inspect every tiny stigma.
Stone fruit is a common name for a drupe, a fruit with a fleshy outer portion surrounding a hardened inner layer. Mango fits this botanical arrangement: the tough stone encloses the seed, and the edible flesh surrounds it. The stone and the seed inside are not strictly the same structure. This distinction is useful when germinating mangoes, because removing a fibrous husk exposes a seed that still needs gentle handling and suitable growing conditions.
Sunburn is damage caused by excessive sunlight and associated heat on plant tissue. Mango fruit or bark previously shaded by foliage can be vulnerable after sudden heavy pruning, and newly moved nursery leaves can scorch after abrupt exposure. The damage can resemble other blemishes, so consider when exposure changed. Prevent unnecessary sudden canopy removal and acclimate sheltered plants gradually. A sunburned area does not turn back into healthy tissue simply because fertilizer is applied.
SWD stands for spotted wing drosophila, Drosophila suzukii, a small vinegar fly best known as a pest of certain thin-skinned fruits. It should not be used as a catch-all name for every fly around ripe mangoes. Other drosophilid flies often gather at damaged or fermenting fruit, while different fruit-fly groups can be regulated mango pests. Identification and local host information matter before choosing traps, interpreting fruit damage, or making a quarantine or pesticide decision.
SWP means self-watering planter, a general name for a container with a water reservoir or another automatic water-delivery arrangement. Many designs are also sub-irrigated planters, but the label does not guarantee suitability for a mango. Root aeration, an effective overflow, adequate container volume, and monitoring remain important. Fertilizer salts can accumulate if water repeatedly moves upward without periodic appropriate leaching. Adjust operation to the tree's water use instead of keeping the reservoir full in all seasons.
