    Since s, natural plant products have been utilized in controlling the insect-pests in the bulk storages. Grain protection gained economic importance from various insect-pest infestations during storage. Integrated pest management is one of the widely adopted pests control strategies that involves various contact and residual insecticides in addition to the fumigants. Sensory Evaluation 1. The aim of the sensory evaluation The aim is to determine the food quality characteristics and the degree of compliance with the legal requirements and consumer habits. The first and most important parameter of food is the sensory characteristics.

Shepard INSECT PESTS became important in stored grain soon after man first learned to keep grain for seed and food purposes. The human race, in its explorations and migrations, usually carried these insects.

Aluminum Phosphide (phosphine gas - restricted use) (Phostoxin, Fumitoxin, Phoskill, Phosteck, Phosfume Weevil-cide – see specific labels for rates of pellet or tablet use).   Materials and Methods. Experiments on the efficacy of plant extracts, powder and oil as oviposition inhibitors, surface protectants, residual toxicants and contact toxicants against C. maculatus were conducted in the laboratory of the Department of Entomology, Bangladesh Agricultural University. All insect cultures were maintained in a growth chamber in the laboratory at a temperature of 27 Cited by:

Factors affecting the evaluation and use of grain protectants for insect controlAuthor: Archie Tunnock. Factors affecting the evaluation and use of grain protectants for insect control. Factors affecting insect desiccation are likely to affect the efficacy of DEs and these include temperature, humidity, grain moisture content, type of insect, grain type and the length of the storage period.

evaluating the relative importance of loss-causing factors such as temperature, moisture content of grains the presence of insect pest species and the effect of storage structures. Damage to stored grain is easier to categorise by visual observation of the relative amount of damage to the grain and by measuring the amount of weight loss.

Close monitoring of grain temperature and insect populations. There are limited options for managing insects in the grain itself. Grain protectants are expensive, and thus used infrequently. In Montana, diatomaceous earth (Insecto®) can be used effectively for on-farm storage due to.

Entomopathogenic fungi are considered promising microbial control agents for the control of post-harvest insects pest, and their evaluation for this purpose has lately attracted a significant.

pesticides that small-scale farmers can use to reduce the damage that insects do to their stored grain. Research into Use:Pocket Guide No. Controlling insect pests in stored grain Diatomaceous earths are effective, non-toxic alternatives to the synthetic chemical insecticides currently used to fight insect pests in stored grain.

Is combining different grain protectants a solution to problems caused by resistant Insect control during storage of grains can utilize grain protectants.

Decades of continuous use of such as the use of new grain protectants or combined use of available grain protectants. Botanicals to Cope Stored Grain Insect Pests: A Review Manohar Lal1, etc.

may prove to be a better option to control insect pests including storage pests without affecting the quality of grains or seeds and without harming our ecosystem or insect pests. Detection techniques for stored-product insects in grain For studies on insect ecology and evaluation of the e Vec-tiveness of pest management, estimation of insect densities & Noyes, ).

Capture rate is inXuenced by insect species and grain temperature and type of grain (Wright & Mills, ). Pheromones The most common use of File Size: KB. However, for an effective control of stored grain insects various parasitoids, predators, pathogens and other living organisms are employed in natural conditions to suppress the pest : Samuel Adelani Babarinde.

Conventional biological control techniques for possible application in stored-grain pest control, including control by the use of predators, parasites, insect diseases and sterile males, the use of pheromones for pest monitoring, mating disruption or enhanced mass trapping, and the use of resistant crop varieties, are summarised in McFarlane.

Factors affecting the behaviour of beetle pests in stored grain, with particular reference to the development of lures cooling and pest control, as well as the presence of natural enemies and pathogens, all have the potential to affect insect response to a lure. Opportunities for the development of more effective lures are by: 6 INSECT-PEST MANAGEMENT AND CONTROL information on the life history, behavior, ecology, and other factors important in the development of control measures for a pest.

Once an insect pest has been correctly identified and the available information assembled, the appli- cability of various methods of pest management can be considered. Anon.

Annis, P C, Banks, H J and Sukardi (). Insect control in stacks of bagged milled rice using carbon dioxide treatment and an experimental PVC-membrane enclosure. These include oviposition deterrents, sex and aggregation pheromones, produced by the insects themselves, and chemicals associated with their food supply including fungal volatiles.

Chemicals deliberately applied to the grain for pest control can also affect insect by: throughout the grain. Protectants are effective against both beetle and caterpillar pests. A surface dressing (Cap Out) may be applied to prevent insects from entering the top of the grain mass and to control surface infestations of Indian meal moth, when a “protectant” is not used (See Insecticides and Fumigants).

The first part of the book contains a list of 17 species of insect pests of stored rice, and general information on storage losses, factors affecting infestability, sources and Cited by: And at 43° there was virtually no insect activity. So keeping grain between 40 and 43 degrees has a big impact on grain storage insect control.

Experts today agree that grain temperature is one of the biggest factors in maintaining stored grain quality.

more years. Grain protectants are insecticides registered for application to whole grain to protect against insect infestations while the grain is in storage.

Grain protectants kill insects as they crawl about or feed on treated grain and/or grain frag-ments. These formulations are generally applied to grain File Size: KB. Management of stored-grain insect pests by farmers or elevator managers should be based upon a knowledge of the grain storage environment and the ecology of insect pests.

Grain storage facilities and practices, geographical location, government policies, and marketing demands for grain quality are discussed as factors influencing stored-grain insect pest management decisions in Cited by:   The using of EPFs for the control of the insect pests in stored-grain products is one of the most promising alternative control methods (Moore et al.

). Especially, the species B. bassiana and M. anisopliae have a wide host range and have been tested against most of the major stored-grain pests (Batta ; Rumbos and Athanassiou ).Cited by: 1.Currently, control of the insect largely depends on the use of synthetic insecticides.

However, the use of synthetic pesticides to protect maize grain against the attack of grain weevil in storage may cause serious health hazards (Talukder and Howse, ), problem of pest resistance and resurgence and is quite expensive to smallholder farmer.
