title: Data from: Assessing the lower thermal limits for development, fecundity, and survival in <em>Anisandrus maiche</em> (Kurentzov)

description: Anisandrus maiche is an emerging ambrosia beetle pest that attacks forest,
 ornamental, and fruit and nut trees, yet little is known about its
 developmental biology or thermal thresholds for reproduction.
 Characterizing thermal ranges for insect pests is critical for
 understanding range expansion, guiding management strategies, and building
 predictive models. Single female A. maiche were placed in artificial diet
 rearing tubes and allowed to develop for up to ten weeks at constant
 10 °C, 14 °C, or 18 °C. No development occurred at 10 °C, although
 foundress females survived for up to eight weeks under these conditions.
 At 14 °C, only a single egg was recovered at five weeks, with no other
 developmental stages observed. Complete development occurred at 18 °C,
 with eggs appearing as early as two weeks post-introduction and all life
 stages appearing at eight weeks, indicating that some development occurs
 at 14 °C, whereas full development occurs somewhere between 14 °C and 18
 °C. Results from this experiment define thermal minimums required for A.
 maiche development and reproduction. This information is the first step
 for understanding the developmental biology of A. maiche and can be used
 to support degree-day-based models and improve management timing for this
 emerging ambrosia beetle pest.
description: Single female <em>Anisandrus maiche</em> were placed
 in artificial diet rearing tubes and allowed to develop for up to ten
 weeks at constant 10 °C, 14 °C, or 18 °C. Three diet tubes were dissected
 twice per week to assess weekly development under constant temperatures.
 No development occurred at 10 °C, although foundress females survived for
 up to eight weeks under these conditions. At 14 °C, only a single egg was
 recovered at five weeks, with no other developmental stages observed.
 Complete development occurred at 18 °C, with eggs appearing as early as
 two weeks post-introduction and all life stages appearing at eight weeks,
 highlighting key thermal thresholds for reproduction and survival. Results
 from this experiment define thermal minimums required for <em>A.
 maiche</em> development and reproduction.

 Description of the data and file structure Data from the controlled
 temperature development experiment. 6 tubes were dissected each week from
 each temperature treatment, and life stages were recorded. The experiment
 was conducted for 10 weeks and replicated 3 times. Columns in the data
 file (Full_maiche.csv) refer to the week of the experiment (week), the
 date of tube dissection (date), the chamber ID that the tubes were in
 (chamber), the temperature in degree Celsius of that chamber (temp), the
 round of the experiment (round; completed 3 full rounds), the rep within
 the weekly dissections (Rep; 1-3), then the number of each life stage
 present during that time (egg, larvae, pupae, male, female), as well as a
 column to note if the original foundress female was deceased (mortality).
