Population Dynamics of Six Major Insect Pests During Multiple Crop Growing Seasons in Northwestern New Mexico

摘要

This study was conducted to monitor the population dynamics of six major insect pests at the NMSU Agricultural Science Center at Farmington (ASC-Farmington) and within an adjacent commercial farm (Navajo Agricultural Products Industry, NAPI) for more effective and efficient pest management during the 2013–2019 period. Specific pheromone traps, sticky and net traps were used to collects moths of beet armyworm ( ), cabbage looper ( ), corn earworm ( ), fall armyworm ( ), potato psyllid ( ), and western bean cutworm ( ). These insects generally appear in early June and their population decreases toward the end of August/early September with different peak times and magnitudes during July and August. was not substantially present in the commercial farm due to intensive insecticide application. Overall, all six insect species were present at ASC-Farmington, with relative abundance, in percent of the total collected moths by all traps, varying from 6.5 to 19% for , 16 to 29.2% for , 1.5 to 20.6% for , 10 to 25% for , 18.5 to 25.6% for and 8.5 to 26.9% for . In NAPI’s commercial field, while the potato psyllid was not recorded, and showed decreasing rates that varied from 27.5 to 4.2% and from 49.3 to 7.8%, respectively. and showed increasing rates varying from 2.9 to 28%, from 7.8 to 25.3% and from 10.9 to 52%, respectively. The results of this study could serve as a guideline for sustainable management strategies for each of the six species for production profitability.
