Equipment for pest management of stored grains
TNAU insect chase trap
Using a trap to find pests hidden in stored grain is a relatively alternative method. There are three major components to this trap: the main tube, the insect trap, and the detachable cone at the bottom.
2 mm at equal distances in the main tube. It makes holes of diameter.
Insects love air and attracted to air. It uses the same thing in this technique.
Insect traps include wheat, rice, etc. In similar grains, the white cone has raised in such a way that it comes down as shown in the figure. The top red cover should be level with the grain. Insects will attract to the air in the main tube and enter through holes. Once inside, they fall into a detachable cone at the bottom. After that, they will have no way out and will stick there forever. This white cone can removed once a week to kill pests.
No chemicals, no side effects, no maintenance costs.
These traps include food-borne insects and especially stored grain Rhizopertha Dominica (F), Cytophilus crazy (L), and Tribolium castaneum (Herbst) insects; Performs excellent performance in detection. It has also found to perform better than standard normal sampling (spare sampling) in the number of insects caught and detected. Insect detection rate (trap: normal sample) found to be higher in the trap than the normal sampling method. These ratios ranged from 2: 1 to 31: 1. Trapped insect traps: Normal samples ranged from 20: 1 to 121: 1.
Combined 2-3 traps / 25 kg. These traps serve as excellent group traps when used in boxes (28 cm in diameter and 39 cm). For this, it should place them in the top 6 inches of the grain. Insect movement is high in this area during the early stages of storage. These traps can dispose of over 80% of the pests in 10-20 days.
TNAU Pit Traps
This trap helps to catch insects that are active on the surface of the grain and in other layers. (Monitoring and group trap equipment)
The standard pattern comprises two parts: a perforated lid (2 or 3 mm in diameter) and a conical part at the bottom. This process is tedious.
This model has a perforated lid, a conical part at the bottom, and a funnel-shaped tap trap attached to the bottom. This eliminates the need to use sticky substances. The commercial model is in plastic and is simple and inexpensive. Easy to handle (only Rs. 25 per trap)
TNAU two in one model trap
The new two-in-one model trap is a combination of a perforated tube, an insect trap system, a chase trap with a storage tube, and a conical pit with a perforated cover and a trap with a pointed angle at the bottom. Combining the two traps increases the insect trap. This is very useful for insects in pulses as these insects roam the surface of the grain. It does not have the tedious process of applying a sticky substance on the inside of the cone to catch insects. In this, it catches the insects alive, so the pheromones secreted from them increase the chances of attracting more and more insects to the trap.
It has a conical cup with a lid at the top and holes of 3 mm. It attaches a box and a round plate to the bottom of the cup. It coats the plate with a Vaseline-like adhesive. Before storing the pulses, the farmer should take 200 gm of pulses and keep them in a cup. When the number of insects increases, because of their habit of wandering, they enter the holes and fall into the trap. The farmers can easily detect these sticky substances, and they can take the grains to dry in the sun. They can use equipment with holes of 2 mm for cereals. This helps to reduce the number of insects in the beginning so that the incidence of insects decreases later. Also, finding insects from time to time helps to save valuable grains.
TNAU automatic pest cleaning bin
This box destroys the insects on its own. This box has four major parts: box, inner perforated box, storage container, and lid. The box takes advantage of the insect’s habit of wandering around in the stored grain and being attracted to airy parts. It stores the grain in a perforated container inside the container. The playful air between the indoor and outdoor compartments provides better ventilation to the insects. When the insects are wandering, they enter the hole to get air and slip and fall into the storage container. It uses perforated sticks in the inner box to catch insects quickly.
This box is useful for storing rice, wheat, pulses, fenugreek, etc. This box can protect the grain from pests such as rice weevil, grain borer, red flour beetle, saw tooth beetle. This helps to destroy over 90% of the pests in just 10 days.
Insect damage was only 1-4% in grains stored for 10 months in automatic pesticide bins (100 and 500 kg). The same proportion was 33 to 65% after 10 months of storage in a simple container. After 10 months r. Dominica, S. The number of Orizai insects was 0-2 per kg in 100 kg automatic pesticide bins, while the same number was 5-191% per kg in simple bins. Was.
