Araucaria

Spider mites are tiny arachnids (less than 1/20 inch long) related to spiders and ticks that feed on plant sap. They thrive in hot, dry conditions and can cause significant damage to ornamental and vegetable plants. During severe infestations, crop losses can reach 14% or higher as these pests disrupt vital plant processes including photosynthesis, carbon dioxide absorption, and transpiration.

Mealybugs are small, soft-bodied insects covered with a white, waxy, cottony material. They are common pests of houseplants and outdoor plants in mild climates. These sap-sucking insects feed on plant tissue, causing damage, stunted growth, and can lead to plant death if left untreated. They produce sticky honeydew which attracts sooty mold.

Scale insects are small sap-sucking pests that appear as brown, shell-like bumps on plant stems and leaves. There are over 25 species, divided into armored (hard) and unarmored (soft) scales. They feed by piercing plant tissue and extracting sap, which weakens the plant and can lead to yellowing, stunted growth, and even death if left untreated. They also excrete honeydew, which attracts ants and promotes sooty mold growth.

Lack of light, also known as etiolation, is an environmental condition that occurs when a plant does not receive adequate light for normal photosynthesis and growth. Without sufficient light, the plant cannot produce enough chlorophyll, leading to pale coloration, weakened tissues, and abnormal elongation as the plant stretches toward any available light source. Etiolation affects virtually all plant species, from sun-loving tropicals to shade-tolerant houseplants. While the condition is not contagious, it progressively weakens the plant over time, making it more susceptible to pests, disease, and physical damage. Prompt correction of lighting conditions is essential to reverse the effects and restore healthy growth.
