Pentatomidae
Pentatomidae is a family of insects belonging to the order Hemiptera, generally called shield bugs or stink bugs. Pentatomidae is the largest family in the superfamily Pentatomoidea, and contains around 900 genera and over 4700 species.Robert G. Foottit, Peter H. Adler ''Insect Biodiversity: Science and Society'', John Wiley and Sons, 2009, As hemipterans, the pentatomids have Hemiptera#Mouthparts, piercing sucking mouthparts, and most are herbivore, phytophagous, including several species which are severe pests on Agriculture, agricultural crops. However, some species, particularly in the subfamily Asopinae, are predatory and may be considered beneficial. Etymology The name "Pentatomidae" is from the Greek language, Greek ''pente'' meaning "five" and ''tomos'' meaning "section", and refers to the five segments of their antennae. Pentatomids are generally called "shield bugs" in British English language , English, or "stink bugs" in American English. However, the term shield bu ...

Pentatomoidea
The Pentatomoidea are a superfamily of insects in the Heteroptera suborder of the Hemiptera order. As Hemiptera, they share a common arrangement of sucking mouthparts. The roughly 7000 species under Pentatomoidea are divided into 21 families (16 extant and 5 extinct). Among these are the stink bugs and shield bugs, jewel bugs, giant shield bugs, and burrower bugs. Description The Pentatomoidea are characterised by a well-developed scutellum (the hardened extension of the thorax over the abdomen). It can be triangular to semielliptical in shape. The antennae typically have five segments. The tarsi usually have two or three segments. Shield bugs have prothoracic glands (in their thoraces, between the first and second pair of legs) that produce a foul-smelling liquid, which is used defensively to deter potential predators and is sometimes released when the bugs are handled. These prothoracic glands are also present in the nymphs, which are similar to adults except smaller ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nezara Viridula
''Nezara viridula'', commonly known as the southern green stink bug (USA), southern green shield bug (UK) or green vegetable bug (Australia and New Zealand), is a plant-feeding stink bug. Believed to have originated in Ethiopia, it can now be found around the world.Squitier J.M. (1997, updated 2007) Southern green stink bug»Featured creatures, University of Florida Institute of Food and Agricultural services. Because of its preference for certain species of legumes, such as beans and soybeans, it is an economically important pest on such crops. Description The adult males can reach a body length (from front to elytral apex) of about , while females are bigger, reaching a size of about . The body is usually bright green and shield-shaped and the eyes are usually reddish, but they may also be black. There is a row of three white spots on the scutellum. They differ from the similar green stink bug (''Chinavia hilare'') by the shape of their scent gland openings, which are shor ...

Aldehyde
In organic chemistry, an aldehyde () is an organic compound containing a functional group with the structure . The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group. Aldehydes are common and play important roles in the technology and biological spheres. Structure and bonding Aldehydes feature a carbon center that is connected by a double bond to oxygen and a single bond to hydrogen and single bond to a third substituent, which is carbon or, in the case of formaldehyde, hydrogen. The central carbon is often described as being sp2- hybridized. The aldehyde group is somewhat polar. The C=O bond length is about 120-122 picometers. Physical properties and characterization Aldehydes have properties that are diverse and that depend on the remainder of the molecule. Smaller aldehydes are more soluble in water, formaldehyde and acetaldehyde completely so. The volatile aldehydes have pungent odors. Al ...
