“…The pupa viability of E. connexa had similar values to those of this predator with C. atlantica (Oliveira et al 2004) or D. noxia and R. padi (Miller 1995;Miller and Paustian 1992). The duration of the pupal stage of E. connexa was short, but with high viability in treatments T13 and T16.…”

The ladybug Eriopis connexa (Germar) (Coleoptera: Coccinellidae) is an important natural enemy of various pests. The potential of rearing it on 17 different diets was evaluated. The percentage of E. connexa adults was higher when its larvae received only eggs of Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae) after freezing for 1 day (92.5%) or combined in artificial diets with honey and water (82.5% to 100.0%). The viability from larvae to adult was 72.5% with eggs of A. kuehniella (after 1 day's freezing) plus an artificial diet based on pet food. No adults of E. connexa were obtained with artificial diets as a standalone food source. The duration of the larval period to adult of this predator was longer, but with low viability, with only A. kuehniella eggs (after 6 months' freezing) or with eggs + artificial diets. Eggs of A. kuehniella (after 1 day's freezing) supplied separately or along with artificial diets were more appropriate to rear E. connexa and both diets can be used for mass rearing of this natural enemy.

“…The number of E. connexa instars was the same as that of this predator fed on Coccinella undecimpunctata (L.) (Coleoptera: Coccinellidae), Megoura persicae (Buckton) and Aphis fabae (Scopoli) (Hemiptera: Aphididae) (Cabral et al, 2006); Diuraphis noxia (Mordvilko) and R. maidis, D. noxia, Acyrnothosiphon pisum (Harris) and Myzus persicae (Sulzer), Cinara atlantica (Wilson) (Hemiptera: Aphididae) (Miller and Paustian, 1992;Miller, 1995;Oliveira et al, 2004) and with Scymnus (Neopullus) sinuanodulus Yu and Yao (Coleoptera: Coccinellidae) (Lu et al, 2002). Generalist predators obtain better nutritional balance by including different sources to complement their diet (Roger et al, 2000;Snyder and Clevenger, 2004).…”

Eriopis connexa (Germar) (Coleoptera: Coccinellidae) occurs in several countries of South America and its mass rearing is important for biological control programmes. This work evaluated biological aspects of E. connexa larva fed on eggs of Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae) and Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) frozen for one day, fresh eggs of Diatraea saccharalis (Fabricius) (Lepidoptera: Pyralidae), S. frugiperda newly-hatched caterpillars, nymphs of Rhopalosiphum maidis (Fitch) and Schizaphis graminum (Rondani) (Hemiptera: Aphididae). Duration of larva, pupa and larva to adult stages differed among prey offered, whereas the prepupa stage was similar. Larva, pupa, prepupa and larva to adult viabilities were equal or major of 87.5% in all prey, except for larva fed on newly-hatched larvae of S. frugiperda. Eriopis connexa has good adaptation to different prey corroborating its polyphagous feeding habit, which evidences the potential of this natural enemy for controlling corn and sorghum pests.Keywords: Anagasta kuehniella, Diatraea saccharalis, Rhopalosiphum maidis, Schizaphis graminum, Spodoptera frugiperda. Aspectos biológicos de Eriopis connexa (Germar) (Coleoptera: Coccinellidae) alimentada com diferentes insetos-praga de milho (Zea mays L.) e sorgo [Sorghum bicolor L. (Moench.)] ResumoEriopis connexa (Germar) (Coleoptera: Coccinellidae) ocorre em vários países da América do Sul e sua criação massal é importante para programas de controle biológico. Este trabalho avaliou os aspectos biológicos de larvas de E. connexa alimentadas com ovos de Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae) e de Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) congelados por um dia, ovos frescos de Diatraea saccharalis (Fabricius) (Lepidoptera: Pyralidae), lagartas de S. frugiperda recém-eclodidas, ninfas de Rhopalosiphum maidis (Fitch) e Schizaphis graminum (Rondani) (Hemiptera: Aphididae). A duração da fase larval, pupal e de larva a adulto diferiu entre as presas oferecidas; entretanto, a fase de pré-pupa foi semelhante. A viabilidade larval, pré-pupal, pupal e de adultos foi maior ou igual a 87,5% em todas as presas, com exceção para larvas alimentadas com lagartas recém-eclodidas de S. frugiperda. Eriopis connexa tem boa adaptação a diferentes presas, corroborando seu hábito alimentar polífago, o que evidencia o potencial desse inimigo natural para o controle de pragas de milho e sorgo.

“…They are predators in both their adult and larval phases, presenting an intense search for food and predatory capacity (Vandenberg, 2002;Olkowski et al, 1990;Oliveira et al, 2004). They are considered important agents in biological control helping to regulate the population of pest insects in many economically important crops (Obrycki and Kring, 1998).…”

Biology and fertility life table of Eriopis connexa, Harmonia axyridis and Olla v-nigrum (Coleoptera: Coccinellidae)

The coccinellids Eriopis connexa (Germar), Harmonia axyridis (Pallas) and Olla v-nigrum (Mulsant) are important natural biological control agents. The purpose of this paper was to study the biology and create a fertility life table of these three coccinellid species. For the biology study, 50 insects/species were used and kept in groups of 10 in glass vials (2300cm 3 ). For the three species studied, the viability of the total cycle varied from 45 to 50%. O. v-nigrum was the species which presented the longest oviposition period. However, H. axiridis demonstrated the best reproductive performance and ability of population growth in each generation. In conclusion, the use of commercially obtained pollen and A. kuenhiella eggs enables the development of coccinellids E. connexa, H. axyridis and O. v-nigrum under laboratory conditions, since the insects completed their biological cycle and originated adults with good reproductive performance.
