The coleoptera order is represented in upwards of 350 000 different known examples throughout worldwide - making them the largest order of the animal kingdom. Beetles are unique in every insect way and appropriately diverse, coming in many varied shapes , forms and colors and each can be found in equally diverse environments suiting their particular lifestyles and food requirements
Beetles are unique in every insect way and appropriately diverse, coming in many varied shapes , forms and colors and each can be found in equally diverse environments suiting their particular lifestyles and food requirements They are found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates.
Many beetle species are helpful, and they eat other pests, like aphids and mosquitoes. However, beetles that bore and eat their way through wood, in their larval stage, can cause a lot of property damage. Beetles also can be major pests that attack stored (potato ,Rice ,dates, Bean , Flour,Wheat ,Corn……)food products, especially in their larval form. The beetle’s life cycle follows a complete metamorphosis – eggs, larva (which cause the most damage), pupa, adult
The term woodboring beetle encompasses many species and families of beetles whose larval or adult forms eat and destroy wood (i.e., are xylophagous).[1] In the woodworking industry, larval stages of some are sometimes referred to as woodworms. The three most speciose families of woodboring beetles are longhorn beetles, bark beetles and weevils, and metallic flat-headed borers.
The palm weevil Rhynchophorus ferrugineus is one of two species of snout beetle known as the red palm weevil, Asian palm weevilor sago palm weevil. The adult beetles are relatively large, ranging between two and four centimeters long, and are usually a rusty red colour—but many colour variants exist and have often been classified as different species (e.g., Rhynchophorus vulneratus). Weevil larvae can excavate holes in the trunk of a palm trees up to a metre long, thereby weakening and eventually killing the host plant. As a result, the weevil is considered a major pest in palm plantations, including the coconut palm, date palm and oil palm.[2]
Oryzaephilus surinamensis, the sawtoothed grain beetle,[1] is a beetle in the superfamily Cucujoidea.[2] It is a common, worldwide pest of grain and grain products as well as chocolate, drugs, and tobacco
The drugstore beetle (Stegobium paniceum), also known as the bread beetle or biscuit beetle, is a tiny, brown beetle that can be found infesting a wide variety of dried plant products
The Khapra beetle (Trogoderma granarium), also called cabinet beetle,[1] which originated in South Asia, is one of the world's most destructive pests of grain products and seeds.[2] It is considered one of the 100 worst invasive species in the world.[3] Infestations are difficult to control because of the insect's ability to survive without food for long periods, its preference for dry conditions and low-moisture food, and its resistance to many insecticides
The date stone beetle or button beetle, Coccotrypes dactyliperda, is an insect belonging to the bark beetles (Scolytinae). It feeds on and spends part of its life cycle in dates, the fruits of the date palm (Phoenix dactylifera). Because of its damage to dates, it is considered a pest.
Adults of the species are reddish-brown and 1.8–2.3 mm (0.07–0.09 in) long, with a convex shape and hairs on the dorsal surface.[1]Characteristic of beetles, they have four wings, with the pair of hardened forewings protecting the pair of hindwings used for flying. They chew a round hole into green unripe dates, causing the fruit to drop 1 or 2 days later.
