Abstract:
Background. Adalia decempunctata L. (Coleoptera: Coccinellidae) ten-spot ladybird beetle, widespread morphologically variable Palearctic species. Materials and methods. DNA polymorphism and infection with Wolbachia, Spiroplasma and Rickettsia symbiotic bacteria were investigated. Results. Eight different haplotypes of the mitochondrial COI gene, seven of which were previously unknown, were found in 92 A. decempunctata individuals from nine European collection places: Prague, Rome, Florence, Hamburg, Paris, Stockholm, Moscow, Feodosia and Yalta. A. decempunctata is less variable in mtDNA compared to A. bipunctata. Symbiotic bacteria Wolbachia and Spiroplasma were not detected. Only Rickettsia infestation was found in A. decempunctata specimens, gathered in Stockholm and Feodosia. Rickettsia from A. decempunctata from Feodosia and Stockholm differ by 0.5% in gltA gene. Rickettsia from A. decempunctata from Feodosia is clustered with Rickettsia from A. bipunctata and Coccinella sp. based on the analysis of the gltA gene. Conclusion: Three of the eight mtDNA haplotypes are present in the A. decempunctata gene pool from geographically distant habitats. A small amount of nucleotide substitutions between Rickettsia from A. decempunctata and A. bipunctata suggests a single origin of the symbiont in the ladybirds of the genus Adalia, the results do not exclude subsequent horizontal transfers between individuals of both species.

Abstract:
AbstractThe success or not of ladybirds as biological control agents is dependent on both their foraging behaviour and their individual survival rates. The former is a function of the habitats they utilise; the latter, a consequence of their reproductive strategy. Egg clustering was investigated in two ladybird species, Aphidecta obliterata, a conifer specialist, and Adalia bipunctata, an arboreal woodland generalist. The effect of oviposition substrate (filter papers vs. spruce needles) on clutch size and oviposition preference was also tested. Adalia bipunctata laid significantly more eggs than A. obliterata. The size of egg clusters laid by the two coccinellids varied between species and substrate types. Adalia bipunctata laid larger egg clusters than A. obliterata, with batches reaching a maximum size of 32 eggs on spruce and 41 eggs on paper, while those of A. obliterata contained a maximum of 5 eggs on spruce and 9 eggs on paper. Of the clusters laid by A. obliterata, 18.6% of those on paper and 21.4% of those on spruce contained only a single egg, whereas a minimum of two eggs per cluster were laid by A. bipunctata. Smaller clusters were laid on the spruce cuttings by both species when compared with those laid on the filter paper, but A. obliterata laid significantly more eggs on spruce than on the filter paper (77% vs. 23%), whilst A. bipunctata laid significantly more eggs on the filter paper (91%). It is suggested that coccinellid eggs are more likely to be washed off spruce needles than broad leaves and that, by laying smaller egg clusters on spruce, A. obliterata reduces this risk. Adalia bipunctata usually lays its eggs on the underside of broad leaved trees and thus does not face this risk and thus can lay larger egg clusters. No differences in cannibalism rates were found between the two species. These findings have implications for the use of ladybirds as biological control agents in spruce forests.

Abstract:
Des expériences effectuées dans le passé ont démontré que les coccinelles aphidiphages évitent de pondre en présence d'une phéromone anti-oviposition présente dans les traces larvaires. La réponse des femelles aux traces larvaires n'a toutefois été démontrée qu'en conditions de laboratoire. Dans une première partie, ce travail confirme en milieu naturel l'effet anti-oviposition des traces larvaires de la coccinelle Adalia bipunctata. Dans un deuxième temps, des expériences de laboratoires mettent en évidence que la réponse des femelles A. Bipunctata aux traces larvaires est plastique et qu'elle varie en fonction de l'âge et de l'expérience. Cette plasticité est conforme aux prédictions de la théorie de l'affouragement optimal. Finalement, dans la troisième partie, il est démontré que la présence de pucerons de bonne qualité (Acyrthosiphon pisum) ou de qualité moyenne (Aphis fabae) n'influence pas la décision de ponte des femelles
It has been demonstrated in previous laboratory experiments that females of the aphidophagous ladybird beetle Adalia bipunctata (L. ) avoid laying eggs in presence of an oviposition-deterring pheromone laid by conspecific larvae. However, this behaviour well studied in laboratory conditions has never been demonstrated in the field. The first part of this thesis demonstrate that females avoid laying egg and spend less time on plants marked with the oviposition-deterring pheromone. The second part shows that the response of A. Bipunctata to oviposition-deterring pheromone is not fixed but change in function the females' age and experience. In the third part, it is shown that the presence of a good quality aphid (Acyrthosiphon pisum) or a bad quality aphid (Aphis fabae) does not influence the oviposition behaviour of the female

Abstract:
During the 1990s, over a period of just a few years, the multi-colored Asian lady beetle, Harmonia axyridis (Pallas) invaded the entire area of northern Europe. In parallel with this invasion, a decline in native coccinellid species was recorded in Belgium, Britain, and Switzerland, affecting mainly one common species: the two-spot ladybird, Adalia bipunctata L. An impressive trait of H. axyridis, that could explain both its high invasiveness and the decline of native coccinellids, is its predation behaviour. Intraguild predation is a trophic interaction between species that share the same prey – in this case, aphids. In order to determine the precise impact of this predation on the native coccinellid species, the predation behaviour of H. axyridis larvae was observed in Petri dishes and on plants. The resistance of H. axyridis to predation was also studied by exposing it without dorsal spines to native predator larvae, in order to test whether or not the dorsal spines are a physical defence against intraguild predation. In addition to these laboratory experiments, an original method was developed and used to track predation under field conditions. This method is based on the gas chromatography–mass spectrometry (GC-MS) detection of exogenous alkaloids in H. axyridis, especially alkaloids from native coccinellids likely to be subject to intraguild predation. My results show that, in the absence of aphids, H. axyridis consumes both A. bipunctata eggs and all larval instars in Petri dishes. On plants, depending to aphid density, this interaction can change with regards to larvae but not eggs. In addition to intraguild predation, competitive exclusion can occur because of quite aggressive behaviour towards competitors. Dorsal spines significantly reduce the number of bites inflicted, and thereby complement the other defense mechanisms of H. axyridis that enable it to remain dominant in competition for food resources. In semi-natural conditions, predation on the native coccinellids Adalia spp. Calvia spp. Coccinella septempunctata L. and Propylea quatuordecimpunctata (L.) was detected. The number of sites where this predation was observed suggests that this interaction is frequent. It was also observed that an H. axyridis larva can ingest several native coccinellid species, confirming its status as a predator of coccinellids. We can therefore conclude that intraguild predation by H. axyridis leads, as does resource competition, to a decline in native coccinellids./Introduite pour la lutte biologique dans les années 90, la Coccinelle asiatique, Harmonia axyridis (Pallas), a envahi en quelques années toute l’Europe du Nord. Parallèlement à cette invasion, un déclin de plusieurs espèces de coccinelles indigènes dont la très commune Coccinelle à deux points, Adalia bipunctata L. a été observé dans différents biotopes en Belgique, en Angleterre ainsi qu’en Suisse. Un des traits remarquables de la Coccinelle asiatique est son comportement de prédateur intraguilde qui pourrait expliquer à la fois ce déclin mais aussi en partie son caractère hautement invasif. La prédation intraguilde est une interaction trophique entre des espèces qui se nourrissent d’une même proie, dans ce cas-ci les pucerons. Afin de mieux connaître l’impact de cette prédation sur les coccinelles indigènes, le comportement de prédation des larves d’H. axyridis a été décrit en boîtes de Petri et sur plantes. Sa résistance à la prédation a également été étudiée en exposant des larves dépourvues d’épines dorsales à un prédateur indigène, dans le but de tester le rôle de ces épines en tant que défense physique à l’égard d’un prédateur intraguilde. En plus de ces expériences de laboratoire, une méthode originale a été développée et utilisée pour suivre cette prédation en conditions semi-naturelles. Elle se base sur la détection, en GC-MS, des alcaloïdes exogènes chez H. axyridis et en particulier des alcaloïdes produits par d'autres espèces de coccinelles susceptibles de subir une prédation intraguilde. Mes résultats montrent qu'en l'absence de pucerons, H. axyridis a un comportement de prédation vis-à-vis des œufs et de tous les stades larvaires d’A. bipunctata. La présence de pucerons, suivant leur densité, peut modifier cette interaction à l’égard des larves indigènes mais pas des œufs. En plus de la prédation intraguilde, une compétition par exclusion peut être aussi suspectée et expliquée par le comportement très agressif d’H. axyridis à l’égard de ses concurrents. Quant aux épines dorsales, elles permettent de réduire significativement le nombre de morsures et complètent ainsi les autres lignes de défense utilisées par H. axyridis pour s’imposer dans des ressources déjà exploitées par d’autres prédateurs. En conditions semi-naturelles, cette prédation à l’égard des coccinelles indigènes a été confirmée vis-à-vis d’Adalia spp. Calvia spp. Coccinella septempunctata L. et Propylea quatuordecimpunctata (L.). Vu le nombre de sites où cette prédation a été détectée, elle peut être considérée comme une interaction fréquente. De plus, une même larve de coccinelle asiatique peut ingérer plusieurs espèces de coccinelles indigènes confirmant indéniablement son statut de prédateur de coccinelles. Ainsi, nous pouvons conclure que la prédation intraguilde par H. axyridis sur les coccinelles indigènes participe très certainement au déclin de celles-ci et ceci très probablement au même titre que des phénomènes de compétition pour les ressources.
