We attempt to determine the effect of the dietary switch from a native to non-native prey on the gut microbiota in the predaceous ladybird Harmonia axyridis larvae and adults and examine how the dietary effect may vary across generations. We fed H. axyridis with different diets, native aphid Megoura japonica (Matsumura) versus non-native mealybug Phenacoccus solenopsis (Tinsley), for 5.

The Asian Lady Beetle, Harmonia axyridis. Larvae complete their development on plants where their primary food (aphids) is abundant. The non-mobile cocoon (pupal) stage remains attached to vegetation by its molted skin, but occasionally may be found clinging to exterior walls of buildings. The average time from egg to adult is about one.

RNA was extracted from whole bodies of both the adult and the larva stage of a single Harmonia axyridis. The quality was verified using a Tapestation 2200 (all RIN scores >8) as well as a Qubit. The initial concentration for the larva sample was 83.2 ng*µL −1, while the initial concentration for the adult sample was 74.7 ng*µL −1.

Here we assessed functional responses of larvae and adult Harmonia axyridis on the 1st, 2nd and 3rd instar of the prey Spodoptera litura across a range of temperatures (i.e., 15, 20, 25, 30 and 35°C). The type and parameters of the functional responses were determined using logistic regression and fitted to the Rogers random predator equation.

However, most studies on nutrition regulation of carnivores mainly focus on protein and lipid, two major macronutrients in preys. In this study, nutrition regulation of protein and carbohydrate has been investigated in the 4th instar larvae of H. axyridis using Geometric Framework. We provided the insects two pairs of foods, one a protein.

The Asia lady beetle alternately called the harlequin multicolored Asian beetle is a member of the family of ladybugs. It is easily recognizable from its red elytra and black spots, though the number of spots and exact coloration varies in each specimen. Most have 19 spots, a few lesser or even more than that, while some may have no spots at all.

Introduction. The multicolored Asian lady beetle, Harmonia axyridis (Pallas), is a well-known aphid predator in its native Asian range (e.g., Hukusima and Kamei, 1970, Hukusima and Ohwaki, 1972, Yasumatsu and Watanabe, 1964).The presumed native distribution of H. axyridis extends from the Altai Mountains in the west to the Pacific Coast in the east, and from southern Siberia in the north to.
