This study was conducted in fields in the Boumerdes region near Algiers, Algeria between April and September 2019. Two species of Coccinellini, Coccinella septempunctata algerica (Kovàr, 1977) and Hippodamia variegata (Goeze, 1777) were recorded as hosts of the parasitoid Dinocampus coccinellae (Schrank, 1802). The percentage of parasitism observed during the sampling was low. Our results suggest that D. coccinellae is not well adapted to Harmonia axyridis (Pallas, 1773). This work shows that the parasitoid has a greater preference for C. septempunctata algerica than for H. variegata (16.7 % versus 2.2 % of parasitism). Given the low percentage of parasitism due to D. coccinellae, it does not seem that this parasitoid is able to reduce the effectiveness of biocontrol by ladybeetles. This is the first published record of Dinocampus coccinellae as a parasitoid of C. septempunctata algerica in Algeria.

The harlequin ladybird Harmonia axyridis (Coleoptera: Coccinellidae) is one of the most common invasive alien species in the world, which has a global impact on biodiversity and agriculture, and causes economic loss and harm to humans. This insect can be infected by different natural enemies, but their interactions remain understudied. In the present study, 581 adult Ha. axyridis specimens were collected from 21 localities in Hungary with the help of citizen scientists and examined for natural enemies. The parasitic nematode Parasitylenchus bifurcatus (Nematoda: Allantonematidae) is reported in Hungary on the harlequin ladybird for the first time. The ladybirds were also infected by the ectoparasitic fungus Hesperomyces virescens (Ascomycota: Laboulbeniales) and parasitoid Dinocampus coccinellae (Hymenoptera: Braconidae). The nematode parasite was present in all localities where Hesperomyces-infected ladybirds appeared. The prevalence of recorded natural enemies varied by locality: for P. bifurcatus it ranged from 1% to 8%; for He. virescens from 2% to 36%; and for the parasitoid it was 4%. Besides, a statistically significant positive correlation was shown between the nematode and the fungus co-infection using Spearman’s correlation. A study on the multiparasitism of harlequin ladybirds was not yet performed in Hungary. The study area is located between two distant areas in Europe where co-infections had already been observed, indicating that this is probably not a sporadic phenomenon, but that parasitism of the harlequin ladybird by multiple natural enemies might be prevalent throughout the area.

Field And Laboratory Conditions

Harmonia axyridis (Pallas) has invaded most continents in the world, including South America. In Chile, it became invasive after 2010, turning into a dominant species in coccinellid guilds in alfalfa crops, where it coexists with the introduced species Hippodamia variegata (Goeze) and the native species Eriopis chilensis Hofmann, the populations of which declined after the invasion of H. axyridis. One of the echanisms attributed to the success of invasive species is the enemy release hypothesis (ERH), which predicts that natural enemies will have a lesser impact on the invasive species in the newly invaded areas than on resident species. Dinocampus coccinellae (Hymenoptera: Braconidae) is a cosmopolitan parasitoid of coccinellids, which vary in their suitability to parasitism according to species and location. The present study evaluated whether H. axyridis is a less suitable host than H. variegata and E. chilensis for D. coccinellae by assessing each step in the parasitism process, from oviposition to adult emergence in field and laboratory conditions. In the field, successful parasitism in H. axyridis (7%) was significantly lower than in H. variegata (33%) and E. chilensis (36%). H. axyridis was also the only species in which failed parasitoid larval development was greater than successful parasitism (adult emergence). In the laboratory, D. coccinellae never successfully oviposited in H. axyridis, while it did in the other two species. These results suggest that in Chile, H. axyridis is a less suitable host than the resident species for D. coccinellae. This mechanism, among others, may explain the dominance of this species in this early stage of invasion

Biological Aspects

The objective of this work was to compare biological aspects and life table parameters of the coccinellids Harmonia axyridis, Cycloneda sanguineaand Hippodamia convergens. Insects were fed eggs of Anagasta kuehniella, and reared at 24.5±1ºC, 70±10% relative humidity, with a 12 hour photophase. Hippodamia convergenstook about 1.6 day to complete development, longer than H. axyridis, and 2.4 day longer than C. sanguinea.At immature stages, H. axyridisexhibited the highest survival percentage (49.2%), in comparison to the other coccinellids. For mean adult longevity, H. convergenswas deficient, in comparison with the other species. Mean period of pre oviposition was the longest in C. sanguinea; the longest oviposition time occurred for H. axyridis; and the post oviposition period was similar between the coccinellids. Considering the reproductive parameters, H. axyridisshowed the best performance in all aspects. For life table, the values of H. convergenswere higher than, although close, to those of H. axyridis. Nevertheless, the high net reproductive rate of H. axyridis showed this species potential to increase population size. The biological characteristics of the exotic H. axyridis favors its invasion and establishment in Brazil, corroborating results noticed in other countries.
