“…The minor components had wider ranges at the optimal mixing ratios than the major two. Pheromonal activity persisted in H. magnanima as long as Z9-14Ac:Z11-14Ac was kept 3:1 (Noguchi et al, 1981). According to Tamaki and Noguchi (1983), the four components were kept for 30 days and 60 days within the optimal mixing ratio for A. honmai males on a plastic cap or a rubber septa, respectively.…”

Long-term pest insect monitoring in agriculture and forestry has advanced population ecology. However, the discontinuation of research materials such as pheromone lure products jeopardizes data collection continuity, which constrains the utilization of the industrial datasets in ecology. Three pheromone lures against the smaller tea tortrix moth Adoxophyes honmai Yasuda (Lepidoptera; Tortricidae) were available but one was recently discontinued. Hence, a statistical method is required to convert data among records of moths captured with different lures. We developed several generalized additive mixed models (GAMM) separating temporal fluctuation in the background male density during trapping and attenuation of lure attractiveness due to aging or air exposure after settlement. We collected multisite trap data over four moth generations. The lures in each of these were unsealed at different times before trap settlement. We used cross-validation to select the model with the best generalization performance. The preferred GAMM had nonlinear density fluctuation terms and lure attractiveness decreased exponentially after unsealing. The attenuation rates varied among lures. A light trap dataset near the pheromone traps was a candidate for a male density predictor. Nevertheless, there was only a weak correlation between trap yields, suggesting the difficulty of data conversion between the traps differing in attraction mechanisms.

The preferred GAMM had nonlinear density fluctuation terms and lure attractiveness decreased exponentially after unsealing. The attenuation rates varied among lures but there were no differences among moth generations (seasons). A light trap dataset near the pheromone traps was a candidate for a male density predictor. Nevertheless, there was only a weak correlation between trap yields, suggesting the difficulty of data conversion between the traps differing in attraction mechanisms.

“…Scouting fields for insects and inspecting for crop damage are the primary ways of monitoring pest populations to determine their levels of infestation (Handique and Roy, 2020). Pheromone traps can also be used to monitor for specific pest insects (Noguchi et al, 1981;Mamun and Ahmed, 2011;Srikumar and Radhakrishnan, 2015). Insect, mite and nematode populations can be reduced by using chemical controls, such as insecticides, miticides, or nematicides, prior to the growing season (Barooah, 2011).…”

Tea is a steeped beverage made from the leaves of Camellia sinensis. Globally, this healthy, caffeine-containing drink is one of the most widely consumed beverages. At least 50 countries produce tea and most of the production information and tea research is derived from international sources. Here, we discuss information related to tea production, genetics, and chemistry as well as production issues that affect or are likely to affect emerging tea production and research in the United States. With this review, we relay current knowledge on tea production, threats to tea production, and solutions to production problems to inform this emerging market in the United States.
