• L’oviposition de l’insecte, c’est-à-dire son choix de déposer ses œufs dans les boutons floraux, répond à des besoins physiques précis, notamment l’épaisseur et la dureté du bouton floral. Certaines espèces de colza sont plus attirantes que d’autres pour le méligèthe dans son cycle de reproduction. C’est donc l’un des buts de ces recherches : détecter les races de colza moins attirantes et les développer au détriment des races plus propices à l’installation des méligèthes.

• An “oviposition attractant” is a substance that causes gravid females to make an oriented flight toward the oviposition substrate (conversely to “repellent”) while an “oviposition stimulant” is a substance that elicits the oviposition behaviour after landing on the substrate (conversely to “deterrent”) [59]. Behavioural assays performed under laboratory conditions are conducted using the two-choice bioassay described previously, and do not allow the separation of short-range (stimulant/deterrent) from long-range (attractant/repellent) cues.

• Aedes japonicus japonicus, first detected in Europe in 2000 and considered established in Germany 10 years later, is of medical importance due to its opportunistic biting behaviour and its potential to transmit pathogenic viruses. Its seasonal phenology, temperature and land use preference related to oviposition in newly colonised regions remain unclear, especially in the context of co-occurring native mosquito species.

• The aim of this field experiment was to optimize oviposition trap settings, including height position, baiting scheme and oviposition surface, for the detection of Aedes mosquito populations, and assessment of their density.

• The inhibition of AOX could efficiently disrupt the development and oviposition of B. glabrata snails, and the intervention targeting AOX at the juvenile stage is more effective for snails. This investigation explored the role of AOX in the growth and development of snails. It would benefit snail control in the future by providing a potential target while using molluscicides more efficiently.

• As the adults emerged from the pupae, one male and one female of the same age were transferred to a plastic oviposition cage (11.3 cm in diameter and 23.4 cm in depth). The oviposition cage was closed at the top with fine mesh netting to aid ventilation. In each cage one leaf disc from each host plant (6.2 cm in diameter) was offered for oviposition. The discs were placed in Petri dishes containing a layer of cottonwool moistened with distilled water. The number of eggs laid by the females was recorded daily and the leaf discs were replaced at that time. The adults were fed with a honey solution (10%).
