“…In the autumn generation, both succinic and melanic females laid earlier when mated to a melanic male, but melanic females laid faster than succinic females regardless of the phenotype of their mate. Berkvens et al , 2007 ). In the spring generation, long egg retention times by melanic females mated by melanic males are expected if females are to increase their chances of re-mating with the more preferred succinic phenotype.…”

“…True (2003) discussed insect melanism in the context of other life history traits, and suggested molecular mechanisms operating at the level of either gene regulation or protein coding could lead to pleiotropic effects on other traits with important biological functions. Similarly, Berkvens et al (2007) measured differences in performance between melanic and succinic phenotypes of H. axyridis , and concluded that the latter had greater nutritional plasticity.

1. We observed native populations of Harmonia axyridis (Pallas) around Beijing, China, over 2 years and performed choice and no-choice mating tests between melanic and succinic (non-melanic) beetles in the laboratory.2. Succinic phenotypes outnumbered melanics by 5:1 in autumn, but melanics became equally abundant in spring, supporting previous inferences that melanism is advantageous in winter, but costly in summer.3. Female H. axyridis expressed mate preference overtly, by rejecting less-preferred phenotypes, and cryptically, by retaining their eggs for longer periods after matings with less-preferred males, ostensibly to replace their sperm.4. Succinic pairs formed more quickly in the spring generation, and melanic pairs in the autumn, and the time to copula was affected by both male and female phenotype. The strength of mate preference was contingent on female phenotype, suggesting melanic alleles had pleiotropic effects. 5. Whereas pair formation was under female control, the duration of copula was under male control and lasted longer in the autumn generation than in the spring. Copulations in the choice test tended to be shorter between similar phenotypes, suggesting that males invested more in dissimilar females when alternative mates were available.6. Although spring and autumn generations were raised under identical conditions, significant contrasts were observed in their reproductive behaviour. 7. Two alternative hypotheses are advanced to explain why gender-specific reproductive behaviours might vary between generations: maternally-mediated epigenetic factors that influence the expression of genes in progeny as a function of maternal environment, and linkage disequilibria among alleles that cycle in frequency seasonally as a function of assortative mating.

“…Means within a column followed by different letters are significantly different (one-way ANOVA followed by Tukey's post-hoc test: P<0.05). Previous work with H. axyridis and C. sexmaculata showed a similar tendency in variation in life-history traits: the period of development would decrease with increasing light period (Berkvens et al, 2008;Wang et al, 2013b). As a common coccinellid species living in cold temperate zones (northern China and the far east of Asia), H. variegata showed generation cycles in rhythm with season (four generations per year).…”

Light is regarded a key environmental cue influencing biological, physiological, and behavioral characteristics in insects. We compared the development, reproduction, locomotion, and predation ability of the predatory ladybird Hippodamia variegata (Goeze) (Coleoptera: Coccinellidae) under various photoperiods, light intensities, and light wavelengths. The results indicated long daylight, high light intensity, and particular colors light (blue, green, and yellow) could benefit H. variegata especially in shortening the period of immature development, increasing mating frequency (shorter mating and pre-oviposition periods), higher fecundity, and a higher proportion of eggs hatched. Average locomotion speed and prey consumption rate of H. variegata increased with prolonged day length and increased light intensity. However, very high intensity of light could inhibit predation rates. Furthermore, green and yellow wavelength conditions increased locomotion speed of H. variegata, and the number of prey consumed increased with increased wavelength. The present study not only revealed significant influences of light conditions on the development and fertility of H. variegata, it also provided sufficient empirical data to improve the efficiency of mass rearing and field releases of this predatory ladybird by regulation of light conditions during biological control applications.

“…In choice tests, there was no difference in the number of attacks by the parasitoid in adult individuals of the laboratory and field populations, and the emergence rate of the parasitoid was similar. However, Berkvens et al (2008a, b) reported differences between laboratory and field populations of H. axyridis in response to food and photoperiod conditions, highlighting that conclusions based solely on laboratory experiments very often cannot be simply extrapolated to the field.…”

Laboratory Investigations Reveal thatHarmonia axyridis(Coleoptera: Coccinellidae) Is a Poor Host forDinocampus coccinellae(Hymenoptera: Braconidae) in Brazil

Harmonia axyridis (Pallas, 1773) is an Asian coccinellid released in several places to act as a biological control agent of aphids. Dinocampus coccinellae (Schrank, 1802) is an endoparasite that uses more than 40 coccinellid species as hosts. Thus, the aim of this study was to investigate the interactions between D. coccinellae and H. axyridis and to determine the impact of the parasitoid on the establishment capacity of H. axyridis. It was also investigate the influence of host on the development of D. coccinellae using other Coccinellidae species as hosts: Cycloneda sanguinea, (L., 1763) Cycloneda pulchella (Klug, 1829), Eriopis connexa (Germar, 1824), and Olla v-nigrum (Mulsant, 1866). In no-choice tests, pupa was the least attacked stage, and the fourth instar and adults the most attacked. In choice tests, the pupa was less attacked when combined with all the other stages, and the fourth instar and adults the most attacked. There was statistical difference only for fecundity, fertility, and number of eggs/day, with higher values found in the non-parasitized control group. Due to the low rate of parasitism it is believed that D. coccinellae has little impact on the populations of this coccinellid in Brazil. However, it is noteworthy that an increase in H. axyridis coverage areas can affect the populations of D. coccinellae, as in some places of occurrence, H. axyridis has become the predominant species of Coccinellidae. The result can be a decrease in populations of this species of parasitoid or its better adaptation to the new host.
