Plodia interpunctella

The   adult moth is 6-9 mm long and in warm areas it can have up to 8 generations a   year, while at 27-30℃ it only takes about 36 days to complete one generation and a   single female can lay up to 300 eggs. It feeds on cereals, dried fruit, seeds   and herbs, as well as sweets, chocolate and milk powder, and even dog food.

Rice weevil

It   prefers to parasitise aged grains such as rice, maize, wheat and sorghum that   have been stored for 2-3 years and feeds heavily on them. The female can lay   up to 500 eggs at a time and up to 8-9 generations can occur each year, so   there is a constant flow of small rice worms in the infested grain. Because   of its rapid growth and reproduction, it is a widespread pest and has a   global geographical distribution.

Trogoderma variabile

Trogoderma   variabile infests a wide range of stored items, such as cereals, cocoons,   woollen fabrics, tweed garments and insect specimens. It is also hardy and   can survive for months or even years in conditions of food scarcity.

Rhizopertha dominica

Rhizopertha   dominica is widely distributed in tropical and subtropical regions of the   world. It prefers to infest cereals, such as rice and wheat. It often casts   the grain into hollow shells and in large numbers often causes fever (up to   38℃ or more) and subsequent mould in stored grain.

Tribolium castaneum

Red   mammoths have a wide range of hosts, and especially likes to eat wheat and   flour. The stink glands on the adult's body secrete a foul-smelling liquid   containing the carcinogen benzoquinone, which causes an irritating fishy   smell to develop in contaminated stores. In addition, the red midge is an   intermediate host for a zoonotic parasite, Pseudanoplocephala crawfordi,   which causes disease in the small intestine of humans and pigs.

Lasioderma serricorne

Native   to the tropical Americas, it is now found throughout the world. A well-known   pest of warehouses, wood, furniture, books, tobacco, food and herbs. It feeds   on tobacco, grains and herbs and causes serious damage to tobacco, cigarettes   and cigarillos.

Callosobruchus maculatus

Native   to tropical or subtropical regions of the eastern hemisphere, the   four-striped bean weevil is now found throughout the world. It causes damage   to red beans, adzuki beans, soybeans, golden beans, mung beans and many other   legumes.

Callosobruchus chinensis

It   is a worldwide storage pest that infests a variety of beans such as mung   beans and cowpeas.

Book lice

Although   not a quarantine pest, it is often intercepted in inbound quarantine. Book   lice include: insectivorous book lice, curlew book lice, small-eyed book lice   and colourless book lice. Booklice are not only a pest of grain but are also   interested in clothing, specimens and books.
