The Lesser Grain Borer (Rhyzopertha dominica) is a small brown to black beetle that damages wheat, corn, rice, and millet. Both the adult beetles and cream-colored C-shaped larvae feed inside and on grain kernels, leaving only dust and thin shells. They can completely develop within kernels, producing large amounts of frass. Proper storage and an economic threshold of 1 insect per quart of grain guides control efforts focused on the aerosol insecticide DFORCE applied to where adults and larvae reside.

In this PPT slides you will come to know about the different kinds of pest which is infesting in WHEAT plant. And also you will come to know about their management practices and also you will have an knowledge about some common chemicals which is being uses to eradicate the pests/diseases infesting in wheat plant.
Most destructive insect devastating the cotton fields of Adilabad district.The presentation has rich in content with realistic photos and management practices.
There are three main types of insects larvae
1. oligopod: Scarabeiform, Campodeiform
2. polypod: Hairy caterpillar, Slug caterpillar, Looper, Semilooper
3. apodous: Euciphalous, Hemicephalous, acephalous
1) OLIGOPOD: a) Campodeiform:
• Have resemblance to the dipluran genus campodea.
• Body is elongate, depressed dorso ventrally and well
sclerotised.
• Head is prognathous.
• Thoracic legs are long.
• A pair of abdominal cerci
is usually present.
• Larvae are generally predators
and are very active.
• Eg: grub of ant lion, grub of lady bird beetle
b) Scarabaeiform:
• Body is ‘C’ shaped, stout and subcylindrical.
• Head is well developed.
• Thoracic legs are short.
• Caudal processes are absent.
• Larva is sluggish, burrowing into wood or
soil.
• Eg: grub of rhinocerous beetle.
Parasitoids and Predators, their attributes.Bhumika Kapoor
Insect parasitoids have an immature life stage that develops on or within a single insect host, ultimately killing the host, hence the value of parasitoids as natural enemies. Adult parasitoids are free-living and may be predaceous. Parasitoids are often called parasites, but the term parasitoid is more technically correct. Most beneficial insect parasitoids are wasps or flies, although some rove beetles (see Predators) and other insects may have life stages that are parasitoids.
where as the Major characteristics of arthropod predators includes adults and immatures are often generalists rather than specialists, they generally are larger than their prey, they kill or consume many prey males, females, immatures, and adults may be predatory and they attack immature and adult prey.
This presentation contains valuable information on major insect pests of stored foods like Angoumois grain moth, Indian meal moth, Rice moth, Potato tuber moth etc.
Stored product insect pest:
Primary grain pests attack the whole grain. The eggs are laid inside the grain, before the larvae mature inside the grain and then chew their way out. Some of these pests include the Lesser grain borer, Granary weevil (Sitophilus granarius, the Wheat weevil) and Rice weevil (Sitophilus oryzae).
Stored product insect pest Cereal grain products and other foods stored in kitchen cabinets, pantries or other areas in the home may become infested with insects or other organisms.
These food invaders are commonly referred to as "pantry pests."
Nearly all dry, stored human food products as well as dry pet food and birdseed are susceptible.
Pantry pests eat and contaminate the products, rendering them useless for consumption and can leave infested foods to crawl or fly around the house.
When this happens, they become an annoyance for many people.

2. Description
Adults
• The adults are 0.1 inch
long.
• Brown to black beetles
with cylindrical bodies.
• Numerous small pits on
the wing covers.
• Head is directed
downward and covered
by the prothorax
3. Grub
• Creamy white.
• C-shaped
• Small dark head that is partly
retracted into the thorax.
• Thorax has three pairs of small legs.
4. Damage
• Lesser grain borers mainly attack wheat, corn,
rice and millet.
• Both the larvae and adults are primary pests.
• Larval and adult feeding in and on grain
kernels.
5. • Leave only dust and
thin brown shells.
• A sweet, musty odor is
often associated with
infestations of this
insect.
6. Biology
• Female deposits her eggs in clusters of 2 to
about 30 on kernels.
• Newly-hatched larvae chew into kernels and
complete their entire development there.
• The larvae can feed on fines or can develop as
free-living insects in the grain.
7. • Both the larvae and adults produce a large
amount of frass or waste.
• Larval fecal pellets are pushed out of the
kernel and large amounts can accumulate in
the grain.
