AbstractHarmonia axyridis is a ladybird extensively used around the world for biological control of agricultural pest. However, it has become invasive in several countries, producing negative ecological and socio-economic impacts. Herein, we review the invasion history of the Harlequin Ladybird Harmonia axyridis (Pallas, 1773) in Ecuador. Although first reported in Ecuador in 2012, museum specimens date back to 2004 and it is currently established across the country, especially along the Andean region. Due to its invasive nature, further studies are urgently needed to evaluate possible impacts of H. axyridis on the Ecuadorian biodiversity and agroindustry.

AbstractDifferences in population growth among four variation types of the ladybird beetle, Harmonia axyridis Pallas, namely succinea, conspicua, spectabilis and aulica, were investigated using various growth parameters. The variation types showed three growth patterns from the intrinsic growth rates (rm), with rates of 0.093–0.099 (for conspicua and aulica), 0.073 (for succinea) and 0.040 (for spectabilis). The growth rates of these patterns were realised in different ways. Spectabilis differed from the other three types in the age and per cent distribution of the specific period to the rm values.

Abstract. Harmonia axyridis (Pallas) is a Coccinellidae species originating from northeast Asia and used in biological control of aphids. As an exotic species is very important to know its natural enemies. Thus, this paper provides the first record of Strongygaster brasiliensis (Towsend)(Diptera: Tachinidae) parasitizing H. axyridis in Southern Brazil.Parasitismo de Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) por Strongygaster brasiliensis (Towsend)(Diptera: Tachinidae)Resumo. Harmonia axyridis (Pallas) é uma espécie de Coccinellidae originária do Nordeste da Ásia e utilizada como agente de controle biológico de afídeos. Como é uma espécie invasora é muito importante conhecer seus inimigos naturais. Dessa forma, este trabalho fornece o primeiro registro de Strongygaster brasiliensis (Towsend)(Diptera: Tachinidae) parasitando H. axyridis no sul do Brasil.

Female Genital

Sperm transfer in the aphidophagous ladybird beetle, Harmonia axyridis Pallas, is by a spermatophore (unpublished data). Although the utilization of spermatophores in insects has been considered to be a more primitive method of insemination than direct sperm transfer, males of many orders produce spermatophores (Chapman 1969; Gerber 1970; Leopold 1976). The remains of the spermatophore, after the sperm has migrated to the spermatheca, is ejected by the female in some species and dissolved within the female genital tract in others (Chapman 1969; Leopold 1976). In Coccinellidae, Fisher (1959) reported on spermatophore formation of Chilocorus spp. and indicated that the female ejected the empty spermatophore 18–24 h after copulation. In this paper evidence is presented that H. uxyridis females not only eject the empty spermatophore but also feed on it.

While insect predators need high-quality food to reach sexual maturity and reproduce, starvation following adult eclosion may occur when prey are missing in agroecosystems. This study explores whether the type of diet available at eclosion determines the future fecundity of newly emerged adult predators. In a laboratory experiment, three different diets (i.e., flowers of Perilla frutescens (L.) Britton, eggs of Ephestia kuehniella Zeller as prey, or no food) were offered to adult females of the ladybird beetle Harmonia axyridis Pallas during their first three days after adult eclosion. On the fourth day, each female was paired with a prey-fed male and the pair was subsequently fed with prey. Diet at eclosion did not affect pre-oviposition time, the number of eggs oviposited daily, or the viability of egg batches. High variability in pre-oviposition time among females was observed for all diets. Significant negative linear relationships were found between pre-oviposition time and both the number of eggs oviposited daily and the viability of egg batches. This study clarifies that the food readily available at adult eclosion does not affect the capacity of H. axyridis to reproduce, provided that adults find prey within a few days. More generally, it shows that the reproductive traits of H. axyridis allow this generalist predator to be highly adapted to heterogenous environments in its native range. It is concluded that the variety of habitats offered by diversified agroecosystems may highly benefit the ladybird beetle H. axyridis, and potentially enhance its ability to biologically regulate crop pests.
