CARICA PAPAYA CHARACTERISTICS TAXONOMIC CLASSIFICATION Carica papaya is native in the north-tropical Western Hemisphere. Some have suggested a centre of origin in Central America or the south of Mexico. Manshardt and Zee (1994) found wild papayas in the Caribbean coastal lowlands of southern Mexico and northern Honduras. Kingdom: Plantae Phylum: Magnoliophyta Class: Magnoliopsida Order: Violales Family: Caricaceae Genus: Carica Species Carica papaya
MEALYBUG CHARACTERISTICS TAXONOMIC CLASSIFICATION Mealybugs are soft, oval, wax-covered insects that feed on many plants in garden, landscape, and indoor settings. Usually found in colonies, they are piercing-sucking insects closely related to soft scales but lack the scale covers. Like soft scales, they can produce abundant honeydew and are often associated with black sooty mold. Mealybugs are favored by warm weather and thrive in areas without cold winters or on indoor plants. Kingdom: Animalia Phylum: Arthropoda Class: Insecta Order: Hemiptera Suborder: Sternorrhyncha Superfamily: Coccoidea Family: Pseudococcidae
ANTATOMY OF MEALYBUG Mealybugs are slow-moving, small, oval insects that are covered with a white, cottony wax. They are tropical insects that are typically only found on perennial foliage plants, and rarely on flowering or bedding plants. They can infest all plant parts including the roots. Mealybugs are related to scales. The citrus mealybug (Planococcus citri) is the most common greenhouse species and is the most damaging.

APHID CHARACTERISTICS TAXONOMIC CLASSIFICATION Size and Appearance Antennae Feeding Habits Winged and Wingless Forms known as plant lice, are small insects that belong to the order Hemiptera. They are known for their ability to infest a wide range of plants, including agricultural crops and ornamental plants. Kingdom: Animalia Phylum: Arthropoda Class: Insecta Order: Hemiptera Suborder: Sternorrhyncha Superfamily: Aphidoidea
ANTATOMY OF APHID All aphids are pretty small (between approximately 1/16 and 1/8 inches long). In addition to six legs and a body, aphids have antennae. Antennae attach near their eyes and are angled back over their bodies. They also have two little “spikes” that protrude from their rear end.

GRASSHOPPER TAXONOMIC CLASSIFICATION scientific name: Schistocerca common name: Grasshopper Kingdom: Animalia Phylum: Arthropoda Class: Insecta Order: Orthoptera Suborder: Caelifera Infraorder: Acrididea
nymphs and adults suck the sap from the lower leaf surfaces through their piercing and sucking mouthparts. While sucking the plant sap, they also inject toxic saliva into the plant tissues, which leads to yellowing. When several insects suck the sap from the same leaf, yellow spots appear on the leaves, followed by crinkling, curling, bronzing, and drying, or “hopper burn”. DAMAGE SYMPTOMS
