Pest control traps

Most emphasis is placed on a program of rigorous preventive maintenance. Appropriate climate conditions can help to prevent mold attack, which typically only occurs at elevated relative humidity. Storage furniture which provides an effective barrier for insects, regular inspection of the collections, monitoring of all collection areas with insect traps, and access control measures which minimize the chance of insect entry into the collection areas, are some aspects of an effective pest control management program (175).

Sex pheromones, chemicals that attract one sex of an insect to the other, also have uses in pest control. They are often utilized with traps to monitor the number of pest insects in an area, and when applied in the field at higher levels, they can disrupt reproduction or egg laying. 

Traps—Traps are sometimes desirable in vertebrate pest control. Leg-hold traps have been used traditionally, but such traps are nonselective and may injuie nontarget animds. Traps which quickly kill only target pests are more desirable. Traps should be checked daily to maintain their effectiveness. 

Cut away and destroy severely infested plant parts. Use blue sticky traps to monitor and trap pests. Encourage native predators such as pirate bugs, lacewings, and lady beetles. Insecticidal soap sprays give some control of thrips populations, but may affect beneficials as well. To limit thrips infestation, dig corms early in fall and cut off tops before thrips move down into corms. Bag and discard debris. Dust corms with pyrethrin to control thrips in storage. Or soak them in a Lysol solution (IV2 tablespoons in 1 gallon water) for several hours before planting. 

Flower buds die petals distorted growth stunted. Cause Thrips. Several species of tiny thrips infest irises Japanese irises are especially susceptible. Thrips feed on inner folds of leaves, causing stunted growth and russet or sooty areas on leaves. Tops of plants eventually turn brown and die. Flowers may appear discolored, flecked with white, or deformed. These pests are difficult to control, for they burrow into plant tissue. Don t buy sickly looking irises that may be infested. Remove and destroy severely infested plant parts. Use blue sticky traps to monitor and trap pests. Applications of insecticidal soap may provide some control once pests are spotted in traps. 

Trunk bands act as barriers and traps to control pests that crawl along tree trunks on their way to the foliage or to the soil. 

Folded burlap strips can also trap pests as they travel up the trunk. Cut a 20" wide strip of burlap fabric and wrap it around the trunk. Tie it to the tree with a cord in the middle of the strip, and let the top half fold down over the bottom, forming a pocket that will trap pests. You can apply a solution of parasitic nematodes to the burlap for added control. Seal bands at the edges with a layer of sticky ointment to prevent other pests from crawling under them. 

Starches like ordinary baking flour and potato starch dextrin work to control insect pests by gumming up the leaf surfaces, trapping and holding the critters until they die. Flour is an old-fashioned pest control, but dextrin is the object of recent attention by researchers looking for new and safe insecticides. Dextrin is actually a sticky sugar extracted from potato starch.

Monitoring the population densities of endemic pests with pheromone traps has been done successfully for decades against scores of species worldwide. When pheromone traps are used for monitoring, they are widely spaced and are at such a low density that they have no effect on reducing population density by themselves. They only serve as sentinels to trigger, at some threshold capture level, the application of other pest control techniques such as insecticide sprays against larvae at some later date that is often based on accumulated thermal units (Baker 2008). 

The actions of I. a. are used in crop protection as decoy substances they attract insects either for subsequent eradication (insect traps) or for population control before or after treatment with insecticides or for collection for scientific purposes. In pest control with... 

The use of single semiochemicals in the field is not usually sufficient for pest control, but by combining semi-ocheinicals, substantial protection can be achieved using an integrated approach called the push-pull system. The push is located in the crop and may comprise antifeedants, nonhost semiochemicals, attraction of predators or parasitoids, oviposition deterrents, or epideictic pheromones. The pull component comprises lures or trap areas away from the crop containing the sex pheromone, host odors, oviposition... 

Knowledge of the specific structures of insect pheromones has permitted their chemical synthesis, allowing their commercial use for the suppression of pest populations by mating disruption (5) (Figure 1). The practical use of pheromone-based pest control products typically takes one of two forms. Either the pheromones are used as discrete baits in traps so that males are drawn into the traps and removed... 

Nowadays, there are three appUcation methods used for pest control in agriculture and forestry monitoring, mass trapping and mating disruption.
