Summary Carpenter ants are so-called because of their habit of chewing wood to create nest sites. They do not eat wood, like termites, but they excavate it with their strong, saw-like jaws to create random galleries where they nest. Carpenter ants are also a nuisance because of their abundance and large size.
Vertebrate Pest Management Insect Management A successful insect management program can best be accomplished by combining IPM techniques, such as accurate pest identification, scouting, monitoring and action thresholds, with biological and alternative preventative control practices and selective insecticide applications if needed.
Use scouting and monitoring techniques to help assess and quantify insect populations over time. Insecticides should be used only when action thresholds have been exceeded or damaging insect populations are present. Action thresholds help minimize insecticide use and crop damage.
Avoid making routine insecticide applications to crops without evidence of insect activity and damage. All insects have natural enemies which, if conserved, can help regulate pest populations. Whenever possible, use selective insecticides that spare beneficial organisms and target the pest you wish to control.
Broad-spectrum insecticides should be used as a last resort. All insecticide applications should be made with ample water and with nozzles directed so that they provide thorough coverage of the plant parts where insects hide. Alternate between insecticide classes or families to help manage insect resistance and extend the life of available products.
Insect Identification Become familiar with the biology and life-cycle of the major insect pests that attack crops on an annual basis. Understanding some basic insect biology often reveals when the pest is most vulnerable to control measures and helps lead to successful management efforts.
Insects usually have either a simple life-cycle, where they grow from egg to nymph to adult, or a slightly more complex cycle, where they mature from egg to larva and then go through metamorphosis in the pupal stage before becoming adults.
You should also be able to identify common beneficial insects and their immature stages i. There are dozens of minor and secondary insect pests that may attack crops on a less frequent basis. Growers should have unknown insects and minor pests identified see Diagnostics section when they are suspected of causing crop damage.
Misidentification often leads to the application of an ineffective pesticide and extensive or chronic crop damage. The application of ineffective or unnecessary pesticides can often reduce the populations of beneficial organisms or natural enemies and lead to secondary insect or mite outbreaks.
An accurate diagnosis of the problem early on can often prevent years of frustration and needless expense. Scouting and Monitoring Crops should be inspected or scouted for insects or damage in a systematic fashion, on a regular basis throughout the growing season.
For many crops and pests, this may mean walking fields weekly, or even more frequently, especially during critical or vulnerable plant development stages. Crops should be scouted in a systematic fashion by walking in an "M" or "W" pattern as you crisscross the field.
Record the average number of insects or damage per plant for each field. Scouting crops always saves money in the long run by allowing for early pest detection, by reducing crop damage and by helping to maintain consistent quality.
Sometimes scouting duties can be performed by other farm members or by hired consultants. Monitoring insect populations with various types of traps black light, pheromone, sticky, baited can supplement or sometimes substitute for information normally gathered during crop scouting.
Insect traps can help you quantify pest pressure that is difficult to see, such as the number of night flying i. The number of insects captured in traps is often used to time scouting activities, predict future pest levels, or is used in conjunction with action thresholds to time sprays and help avoid crop damage.
Action Thresholds Action thresholds tell you when to spray to prevent economic damage to the crop. They also help you avoid applying insecticides to crops when insect populations are low or no pests are present.
Thresholds can be based on the number of insects found per plant, the amount of injury or damage per plant, or the number of insects captured in a trap.As a prerequisite for the development of a more sustainable integrated insect pest and disease management strategy for cashew, information on the biology and ecology of the key insect pests and diseases in a changing environment, and on influencing biotic and abiotic factors, is needed.
about the insect and the key will direct you to the next number and hopefully help you correctly identify the insect in question. This key will include information such as characteristics of the wings, antennae, and body structure of the insect. Key to Insect Orders Author: Leslie Mertz Created Date.

Eggs, immatures, and adults can be found together throughout most of the year. Temperature plays a key role in regulating oviposition, and the greatest numbers of eggs are most commonly deposited in the spring and fall.
Eggs are pearly white to tan, spherical with hexagonal shaped ridges, and laid in clusters. insect-transmitted viral diseases and defects, there is a much lower tolerance for insect damage in seed production.

Biology and Management of Carpenter Ants. sugar-rich honeydew directly from aphids and scale insects that are found feeding on the tree's sap. Honeydew is nearly pure sugar, and is excreted by aphids and scale insects in large quantities during the spring and summer months.
