Temperature-Dependent Bionomics and Modeling of <I>Anarsia lineatella</I> (Lepidoptera: Gelechiidae) in the Laboratory

Abstract

Laboratory studies were conducted to assess the effect of constant temperatures (15, 20, 25, 30, and 35 degrees C) on life history traits of peach twig borer, Anarsia lineatella Zeller (Lepidoptera: Gelechiidae). Developmental rate, survival, longevity, and fecundity were studied in environmental chambers from individuals reared on peach, Prunus persica L., twigs until adulthood. Temperature-dependent relationships of various developmental events were characterized, and applied models were evaluated. Total developmental time ranged from 20.4 d (30 degrees C) to 124 d (15 degrees C). Lower developmental thresholds for egg-to-adult development assessed to 11.2 or 11.8 degrees C, according to a linear weighted regression or the reduced major axis method, whereas development required on average 400 degree days (DD) or 424.4, respectively. Survival was substantially reduced at lower (15 degrees C) and higher (35 degrees C) temperatures. First-instar larvae exhibited higher sensitivities during development in all treatments. Mean longevity ranged from 12.1 d (35 degrees C) to 45.8 d (15 degrees C) and from 10.4 d (15 degrees C) to 50.3 d (35 degrees C) for females and males, respectively. A significantly higher number of eggs was laid at the moderate temperatures (126.9 at 25 degrees C), whereas at the extremes, females laid the fewest (40.4 and 26.3 at 15 and 35 degrees C, respectively). A new model, based on a beta type distribution function, fitted on the temperature-dependant developmental data to predict population dynamics. Relative accuracy of the above-mentioned formula was validated using root mean square error (RMSE), index of agreement (d) and the mean square error quotient (E1,2) with respect to a proved model.

The Effects of Temperature on the Development and Survival of Bathycoelia distincta (Hemiptera: Pentatomidae), a Significant Pest of Macadamia in South Africa

“…Four non-linear models: Taylor-81 [ 31 ], HarcourtYee-82 [ 32 ], Kontodimas-04 [ 33 ], and Damos-08 [ 17 ], were fitted to the observed developmental rates of B. distincta ’s life stages. In all the model equations, rT is the mean developmental rate (1/day), and T (°C) is the temperature ( Table 1 ).…”

“…Damos and Savopoulou-Soultani 2008 [17] R m : maximum temperature; T: temperature; T m : optimum temperature; T o : rate at which temperature falls away from T m ; a0, a1, a2, a3: constants; aa: constant; T min : minimum temperature; T max : maximum temperature; bb, cc: constants.…”

“…Insects develop at a linear rate at intermediate temperatures but non-linearly at a wide range of temperatures, with slow development at low temperatures, increasing at higher temperatures before decreasing again [ 17 ]. In addition to temperature, factors such as humidity and diet also influence the developmental rate of insects [ 18 , 19 ].…”

Temperature-dependent development of Helicoverpa armigera (Lepidoptera: Noctuidae) at constant temperatures: instar pathways and stage transition models with semifield validation

“…The model list and the evaluated statistical criteria were provided in Supplementary Material (available online), with the definition of corresponding parameters and the estimated parameter values. Among them, 4 models showed a good performance in terms of the statistical criteria: Lactin model (Lactin et al 1995), cardinal Beta distribution (Yan and Hunt 1999), simplified Beta distribution (Damos and Savopoulou-Soultani 2008), and Gaussian model (Taylor 1981). Gaussian model (Taylor 1981) showed a good performance in the data sets, but it was rejected because of its symmetrical characteristic, which can be a factor causing an overestimation of development rates in high temperatures.…”

“…According to the definition of Logan et al [32] and Damos and Savopoulou-Soultani [33], T m is the thermal maximum, ∆T is the temperature range over which "thermal breakdown" became the overriding influence, and ρ is the composite value for critical enzyme-catalyzed biochemical reactions in insect development.…”
