Oryzaephilus acuminatus, is a species of silvan flat bark beetle native to India and Sri Lanka. [1] [2]
The species is very similar to saw-toothed grain beetle, Oryzaephilus surinamensis and the merchant grain beetle, Oryzaephilus mercator . [3] Male is about 3.7 mm and female is about 3.5 mm in length. Adults are dark brown to black. Body is more elongate and covered with recumbent golden setae. Pronotum in large males. Lateral ridges and anterior pronotal angles are strongly developed. Larvae resemble the O. surinamensis. [4]
The natural range of the animal is known to be India and Sri Lanka. In England, the species was imported on coconut shells. The species was originally not found in the United States. However, on 11 January 1983, some beetles were discovered in the storage area in Fort Myers, Florida, which stored Azadirachta indica imported from India to use as insecticides. [4] [5]
The khapra beetle, also called cabinet beetle, which originated in South Asia, is one of the world's most destructive pests of grain products and seeds. It is considered one of the 100 worst invasive species in the world. 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. There is a federal quarantine restricting the importation of rice into the U.S. from countries with known infestations of the beetle. Khapra beetle infestation can spoil otherwise valuable trade goods and threaten significant economic losses if introduced to a new area. Handling or consuming contaminated grain and seed products can lead to health issues such as skin irritation and gastrointestinal distress.
Oryzaephilus surinamensis, the sawtoothed grain beetle, is a beetle in the superfamily Cucujoidea. It is a common, worldwide pest of grain and grain products as well as chocolate, drugs, and tobacco. The species' binomial name, meaning "rice-lover from Suriname," was coined by Carl Linnaeus, who received specimens of the beetle from Surinam. It is also known as the malt beetle and may be referenced in the poem This Is The House That Jack Built in the line "....the rat that ate the malt that lay in the house that Jack built" the malt referenced may not be actual malted grain but a sawtoothed grain beetle.
The foreign grain beetle is a species of beetle in the family Silvanidae. It is related to the sawtoothed grain beetle.
Laemophloeidae, "lined flat bark beetles," is a family in the superfamily Cucujoidea characterized by predominantly dorso-ventrally compressed bodies, head and pronotal discs bordered by ridges or grooves, and inverted male genitalia. Size range of adults is 1–5 mm (0.04–0.2 in) in length. Currently, it contains 40 genera and about 450 species, and is represented on all continents except Antarctica; species richness is greatest in the tropics.
Silvanidae, "silvan flat bark beetles", is a family of beetles in the superfamily Cucujoidea, consisting of 68 described genera and about 500 described species. The family is represented on all continents except Antarctica, and is most diverse at both the generic and species levels in the Old World tropics.
