Glenn explains how to use the new Growing Degree Day model in this presentation from Syngenta.What are they, how you can use them and how to use them to get Washington State University entomologists develop new codling moth models based on trap catch data to pair population insight with phenology for more precise predictions.

Calculating Growing Degree Days

Monitoring tools Codling moth degree-days (DD) and models: Since insect development is dependent on temperature, applying codling moth controls

Site Specific Codling Moth Population Predictions

Common vegetable insects can be monitored using degree days or indicator plants. This factsheet provides degree day information for many common vegetable garden pests.

Chemical control of the OFM can be improved by using a degree-day model to establish the optimum timing of insecticide sprays targeting newly hatched larvae. Since the first insecticide To properly use the model, the biofix must first be set. This is the date that will serve as the starting point for growing degree day accumulation. For this type of model January 1st is the The Oriental Fruit Moth Growing Degree Day Model, developed by researchers, and available on the Pest Prophet app, is a tool growers can use to predict egg hatch based on adult trap

Codling Moth Scientific name: Cydia pomonella Phenology models predict timing of events in an organism’s development. For many organisms which cannot internally regulate their own

The degree-day model used in this guideline for codling moth reflects the concept that each subsequent codling moth generation time is longer than the preceding one.

Maximizing codling moth models

Maximizing Crop Yield: Harnessing Growing Degree Days and Pest Management Models for Integrated Field Operations In the ever-evolving This Montana State University Extension fact sheet discusses the codling moth’s life-cycle, and how integrated pest management can be used for prevention and control.

[Intro] [Data Table] [Data Map] [DD Calc] [DD Models] [Links] This project funded in part by a grant from the USDA-Western Regional IPM program. This page on-line since May Degree day totals are also used for comparing the progress of a growing season to the long-term average. Degree Days Predict When Codling Moths are Flying and When Eggs are Hatching The codling moth Cydia pomonella (L.) (Lepidoptera Tortricidae) is a pest of worldwide importance that exhibits seasonal phenology that is mainly affected by temperature.

Codling moth management Predators and parasites feed on CM, but these natural enemies cannot keep this pest from reaching damaging levels in With codling moth (50 degrees F threshold temperature), on a day when the average temperature was 51 degrees F, one degree day accumulated. These daily accumulations can be added LIBRARY OF DEGREE-DAY MODELS FOR INSECTS AND PLANTS for pest management decision making in Oregon INTRODUCTION As degree-day models for specific insects and

Calculate degree days for codling moth for your location using the codling moth pest model or degree-day table. To learn more about using degree days to time insecticide applications, Because growth of insects is temperature dependent, we measure their development in degree days rather than in days. A degree day is when the average Fundamentals Understanding the fundamentals of codling moth biology, pheromone traps, and degree-day models is critical for implementing control tactics. The fundamentals must be

Optimize first generation codling moth management by using the degree-day model to time interventions and scouting to track thresholds. What would be the difficulty in managing codling moth if growers did not have knowledge of moth phenology? How does degree-day model information change decision-making in pest

Predicting Codling Moth Distribution Shifts in Washington State

These tables are designed to be used with the accompanying text for each pest species for which degree day models have been developed. They may open in a new browser window. Degree Codling moth/pear psylla/mites: use 1% oil, methoxyfenozide (Intrepid 2F), or chlorantraniliprole (Altacor) to kill codling moth eggs. Oil also increases suppression of psylla and mites. These two models have combined into the Gypsy Moth Growing Degree Day Model, available on the Pest Prophet app. This app can be used to predict life cycle stages, which can be used to

The FIlbertworm growing degree day model uses a lower threshold of 50F and an upper threshold of 110F for calculating growing degree day units. The growing degree day units can be

The codling moth is an insect that is a threat to apple production in Washington State. The team used Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) Land Degree Day Models and Weather Data Degree day models correlate ambient temperature with the development rate of codling moth life stages. These models provide a

No upper threshold is used in the models for western cherry fruit fly and apple maggot. Codling moth, peach twig borer, and Lacanobia fruit worm models use the horizontal

IPM degree-day data and models

Control of codling moth in commercial orchards relies on three tools: regular scouting of the trees and fruit, pheromone trapping, and the use of weather monitoring and degree day models.

Use of growing degree days is a tool landscape managers use to identify the best time for their location, enabling them to make highly effective pesticide applications and
