“…Thus, to test reliability of the models developed under constant temperatures, it may be reasonable to compare species performance under a close range of fluctuating temperatures. However, only a few studies have investigated the effect of fluctuating temperatures on mortality and population growth parameters of DBM [ 66 , 68 – 69 ]. Under higher temperature fluctuations of 25 ± 10°C, 57% of the eggs of DBM died at 37°C [ 67 ], which is comparable to 53.3% mortality observed in this study.…”

There is a scarcity of laboratory and field-based results showing the movement of the diamondback moth (DBM) Plutella xylostella (L.) across a spatial scale. We studied the population growth of the diamondback moth (DBM) Plutella xylostella (L.) under six constant temperatures, to understand and predict population changes along altitudinal gradients and under climate change scenarios. Non-linear functions were fitted to continuously model DBM development, mortality, longevity and oviposition. We compiled the best-fitted functions for each life stage to yield a phenology model, which we stochastically simulated to estimate the life table parameters. Three temperature-dependent indices (establishment, generation and activity) were derived from a logistic population growth model and then coupled to collected current (2013) and downscaled temperature data from AFRICLIM (2055) for geospatial mapping. To measure and predict the impacts of temperature change on the pest’s biology, we mapped the indices along the altitudinal gradients of Mt. Kilimanjaro (Tanzania) and Taita Hills (Kenya) and assessed the differences between 2013 and 2055 climate scenarios. The optimal temperatures for development of DBM were 32.5, 33.5 and 33°C for eggs, larvae and pupae, respectively. Mortality rates increased due to extreme temperatures to 53.3, 70.0 and 52.4% for egg, larvae and pupae, respectively. The net reproduction rate reached a peak of 87.4 female offspring/female/generation at 20°C. Spatial simulations indicated that survival and establishment of DBM increased with a decrease in temperature, from low to high altitude. However, we observed a higher number of DBM generations at low altitude. The model predicted DBM population growth reduction in the low and medium altitudes by 2055. At higher altitude, it predicted an increase in the level of suitability for establishment with a decrease in the number of generations per year. If climate change occurs as per the selected scenario, DBM infestation may reduce in the selected region. The study highlights the need to validate these predictions with other interacting factors such as cropping practices, host plants and natural enemies.

“…Temperature significantly affects its development (Marchioro et al, 2016), survival (Marchioro & Foerster, 2011), fecundity (Garrad et al, 2016; Marchioro & Foerster, 2012), distribution (Ngowi et al, 2017) and drug resistance (Steinbach et al, 2017). Most Studies relating to temperature adult and offspring traits have focused on constant temperature (Golizadeh et al, 2009), two‐step temperature change (Ahmad et al, 2008) or short‐term heat attack (Zhang et al, 2013).…”

The development and mortality of diamondback moth, Plutella xylostella (L.), were studied in laboratory at 25 ± 1°C, 65 ± 5% RH, and a photoperiod of 16:8 (L:D) h on 10 canola cultivars: ‘SLM046,’ ‘Opera,’ ‘Okapi,’ ‘RGS003,’ ‘Modena,’ ‘Sarigol,’ ‘Zarfam,’ ‘Licord,’ ‘Hayula420,’ and ‘Talaye.’ Larvae successfully survived on all host plants. The developmental time of immature stages ranged from 15.03 ± 0.15 d on Hayula420 to 16.65 ± 0.29 d on Opera, with a larval period ranging from 7.67 to 8.91 d on these cultivars. Adult female longevity was longest on Hayula420 without any supplemental food. Life table entropy values (H < 0.5) indicated Deevey's type I survivorship curve; however, the value of 0.541 on Hayula420 (H > 0.5) corresponded to type III. Major mortality parameters such as fraction of original cohort dying between successive days of age, death frequency (dx) of immature P. xylostella, average daily mortality (), and central death rate (mx) were evaluated on canola cultivars and indicated that the highest mx occurred on RGS003, with relatively low potential of population growth, on fifth day of life when the pest is in early larval stages (Ll and L2). The early instars are the most susceptible stages and suffer the highest cause-specific mortality under laboratory conditions.
