      Codling moth, Cydia pomonella (L.), is the key pest of pome fruits in many temperate areas of North America, Eurasia, South Africa, South America and Australia. Many predatory arthropods species are found in organic apple orchards of central Washington; here we use PCR-based gut content analysis of arthropod predators to identify predators that attack codling moth. In , Yakima County, WA had a population of k people with a median age of and a median household income of $47, Between and the population of Yakima County, WA grew from , to ,, a % increase and its median household income grew from $45, to $47,, a % increase.

    Yakima County Central Yakima Valley is primarily agricultural, with the well-established small rural communities of Parker, Buena, Zillah, Wapato, Toppenish, Harrah, White Swan and the Yakama Nation. The Yakama Nation covers 2, square miles with an estimated population of o people (on and off. Introduction. Apple is a major cash crop of Balochistan, Pakistan.

Introduction. Codling moth (CM), Cydia pomonella (L.) (Lepidoptera: Tortricidae), is an economically important deciduous orchard pest in the northeastern (Dean, ) as well as in the western U.S. apple growing regions (Beers et al., ).In Pennsylvania, it has been a major pest in all apple growing regions (Hodgkiss et al., ; Worthley and Marston, ) for more than Cited by: Another case study at Codling Moth Areawide Management (CAMP) project sites in Washington, California, and Oregon showed that the number of hectares of farms treated with mating disruption insecticides to control codling moths Family: Tortricidae.

Introduction. Codling moth (CM), Cydia pomonella (L.) (Lepidoptera: Tortricidae), is an economically important deciduous orchard pest in the northeastern as well as in the western U.S. apple growing regions (Beers et al., ).In Pennsylvania, it has been a major pest in all apple growing regions (Hodgkiss et al., ; Worthley and Marston, ) for more than 70 Cited by: Codling moth, Cydia (Laspeyresia) pomonella, is a serious insect pest of apples, pears, and English walnuts.

IDENTIFICATION. Codling moth adults are about 1/2 to 3/4 inch long with mottled gray wings that they hold tentlike over their bodies (Figure 1).

Their appearance blends well with most tree bark, making them difficult to detect. The objective of my study was to compare insect and mite pests and natural enemy population densities in paired organic and conventional apple orchards in the Yakima Valley of Washington.

MATERIALS AND METHODS Study sites. Infive apple growers with both organic and conventional orchards in the Yakima Valley were included in this study. If you grow apples, the codling moth will come.

The larva of this common pest, also known as “the worm in the apple,” directly impacts the eating quality of apples across the state of Washington. When left unmanaged in backyard trees, the codling moth can damage as much as 80 to 95 percent of the fruit—making it “wormy” and unfit to eat. The primary focus of the Horticultural Pest and Disease Board is to serve commercial producers of Yakima County by protecting orchards from invasive pests and diseases of tree fruit.

Pests of tree fruit such as codling moth, pear psylla, cherry fruit RCW and RCW are laws written to protect agricultural producers of Washington State.

Cydia pomonella. by Timothy J. Smith WSU Extension. Codling Moth has been the key insect pest of apples in Washington since the early ’s.

Damage was constant and, despite heavy spraying with lead-arsenate, percent losses were expected yearly in orchards up untilwhen DDT became available to growers. Get this from a library. Life history of the codling moth in the Yakima Valley of Washington.

[E J Newcomer; W D Whitcomb; United States. Department of Agriculture.] -- Pp. The codlling moth, Cydia pomonella, is the key pest of commercial apples in Eastern Washington. Codling moth is also a pest of European and Asian pear fruit. Other crops - walnuts, prune/plum. Outside host plants - Crabapples, hawthorn & quince.

Codling moth is a key pest in apple, pear, crabapple, and Oriental pear trees. The adult codling moth is a small, brown and gray banded moth about 1⁄2 inch long (Figure 1). Difficult to scout for as these moths fly during dusk and dawn, but they can be monitored with traps baited with pheromone lures.

Study of the codling moth population genetic structure has received increasing attention in the last few decades [], because this knowledge can be useful for improving the design of eradications or integrated area-wide pest management strategies using the sterile insect technique (SIT), host plant removal, or mating disruption [5,6,7,8].For instance, the population.

The codling moth (CM) (Cydia pomonella L.) is the most important apple pest from the family Tortricidae causing economic losses in fruit production in Europe and globally [1,2,3,4].Damage to fruit, caused by larval feeding, results in quality and yield losses, therefore, the establishment of effective plant protection measures is a major management issue in apple growing.

A key question regarding use of sterile moths to manage codling moth in BC has always been the inactivity of moths in spring. This phenomenon was observed in pilot studies, in the first years of the current program, and has continued to present (Judd et al., ; Thistlewood et al., ).

The codling moth was discovered in the region in and was the subject of repeated attempts at eradication, until such efforts were abandoned inafter which it became fully established in all pome fruit sites and the key pest of apples. It has two full generations (spring, summer) and a partial third in the region, and overwinters as.

Previous article in issue: Transgenic plants expressing the AaIT/GNA fusion protein show increased resistance and toxicity to both chewing and sucking pests.The results of this study positively suggest the use of pheromones to control the said pest in apple but the life cycle duration of ACBW seems to be synchronized with codling moth in Quetta valley.

Codling moth has already been consider a serious major pest of apple and farmers of the region prefer chemical control than any other control.
