“…Después de iniciada las cópulas hasta la ovoposición pasan por un breve periodo de pre ovoposición, en la cual siguen alimentándose y pueden copular varias veces y con diferentes machos. La ovoposición ocurre generalmente cuando la población de pulgones es alta, los huevos son colocados en las hojas del hospedero de su presa, ya que la elección materna debe de asegurar el alimento de su descendencia (Sicsú et al, 2020), ovoposita en grupos de 20 a 30 aunque hay posturas de más de 50 huevos. El canibalismo es un fenómeno común en esta especie, siendo más susceptibles los huevos y larvas pequeñas que son devorados sobre todo por hembras grávidas y más aún cuando hay escases de alimento (Bayoumy & Michaud, 2015;Khan & Yoldaş, 2018).…”

The Brevicoryne brassicae aphid is an important pest of several plants of the Brassicaceae family worldwide. In the Mantaro Valley-Peru, it causes economic losses in cabbage and broccoli crops. Myzus persicae is the most important pest in potato cultivation. Myzaphis rosarum colonizes both wild and cultivated rose bushes and trees. To control it, farmers use toxic chemical insecticides that cause health problems. Faced with this problem, biocontrol is an important component of sustainable production to control pests. Hippodamia convergens is a predator of aphids, so it is necessary to know its biology and predation in its different prey. The objective was to determine the duration of the development stages, longevity, fecundity and performance of the predator H. convergens reared with cabbage aphids B. barssicae, Myzaphis rosarum and Myzus persicae. The completely randomized design was used, with 10 repetitions and three treatments or species of aphids. The aphid species used as food for the predator influenced the duration of preimaginal and adult development. Egg-adult development was longer with 34.1 days with B. brassicae and shorter with M. rosarum and M. persicae with 22.8 and 22.5 days respectively. Cabbage glucosinolates absorbed by B. barssicae negatively affected the growth rate, development, weight gain, survival, fecundity and predation capacity of H. convergens.

“…Finally, oviposition site selection can help future offspring by favouring proximity to suitable habitats and providing direct access to resources necessary for juveniles. This is the case in the sandpaper frog Lechriodus fletcher (Boulenger, 1890) and several lady beetle species, where females choose oviposition sites that contain the largest quantities of nutritive resources for their future larvae (Sicsú et al 2020;Gould et al 2021).…”

Depositing eggs in an area with adequate temperature is often crucial for mothers and their offspring, as the eggs are immobile and therefore cannot avoid exposure to sub-optimal temperatures. However, the importance of temperature on oviposition site selection is less clear when mothers can avoid these potential adverse effects by both moving their eggs after oviposition and providing other forms of egg care. In this study, we addressed this question in the European earwig, an insect in which mothers care for the eggs during several months in winter, frequently moving them during this period. We set up 60 females from two random natural populations (as this species often exhibits population-specific life-history traits and behaviours) under controlled thermal gradients, and recorded the temperature at which they built their nests, tested whether they moved their eggs after an experimental temperature change, and measured the effects on egg development and hatching rate. Our results demonstrate that females indeed select oviposition sites according to temperature, and can move their eggs to reach warmer temperatures. We also show that these warmer temperatures are necessary to ensure egg hatching. Although this set of behavioural thermoregulations is present in the two tested populations, we found a population-specific modality of expression. These included the range of temperatures explored before oviposition, temperature selected at oviposition and dynamics of egg transport following a temperature change. Overall, our study sheds light on a new post-oviposition strategy in female insects that overwinter with their eggs for coping with temperature changes. More generally, it also reveals that egg care and/or egg transport do not prevent behavioural thermoregulation via oviposition site selection and highlights the diversity of behaviours that insects can adopt to enhance their tolerance to global climate change.

“…Oviposition site selection can also help future offspring by favouring proximity to suitable habitat and providing direct access to resources necessary for juveniles. This is the case in the mosquitoes Culiseta longiareolata and Anopheles punctipennis, where females avoid laying eggs in pounds containing predators or competitors of their future larvae (Petranka and Fakhoury 1991, Spencer et al 2002, Silberbush and Blaustein 2011 and in the sandpaper frog Lechriodus fletcher and several lady beetle species, where females choose oviposition sites that contain the largest quantities of nutritive resources for their future larvae (Sicsú et al 2020, Gould et al 2021. Finally, oviposition site selection can provide direct benefits to eggs by limiting the risks of predators finding the eggs, eggs drying out or egg exposure to toxic pollutants.…”

Depositing eggs in an area with adequate temperature is often crucial for mothers and their offspring, as the eggs are immobile and therefore cannot avoid exposure to sub-optimal temperatures. However, the importance of temperature on oviposition site selection is less clear when mothers have the capability to avoid these potential adverse effects by both moving their eggs after oviposition and providing other forms of egg care. In this study, we addressed this question in the European earwig, an insect in which mothers care for the eggs during several months in winter and often move them during this period. Using 60 females from two Canadian populations (St John’s and Harvey station) set up under controlled thermal gradients, we demonstrated that earwig females both select oviposition sites according to temperature and move their eggs after oviposition to reach warmer environmental temperatures. While this set of behavioural thermoregulation is present in the two studied populations, its modality of expression was population-specific: St John’s females explored greater ranges of temperatures before oviposition, laid their eggs in warmer areas, and moved their eggs quicker toward warm locations. Overall, our study reveals that earwig females have evolved both pre-and post-oviposition behavioural strategies to mitigate the risks inherent to tending eggs during winter. More generally, it also reveals that egg care and egg transport do not prevent behavioural thermoregulation via oviposition site selection and highlights the diversity of behaviours that insects can adopt to enhance their tolerance to global climate change.
