O objetivo deste trabalho foi determinar os aspectos biológicos de Harmonia axyridis, alimentada com duas espécies de presas, e a ocorrência de predação intraguilda com Eriopis connexa. Larvas de H. axyridis foram alimentadas diariamente com ovos de Anagasta kuehniella ou com o pulgão Schizaphis graminum. Adultos da joaninha foram separados em dez casais que receberam o mesmo tipo de alimento da fase larval. Na avaliação da predação, uma larva de quarto instar de cada espécie foi mantida na presença ou ausência de abrigo e de ovos de A. kuehniella. A fase larval de H. axyridis durou 10,2 e 8,9 dias, quando alimentada com A. kuehniella e S. graminum, respectivamente. A sobrevivência do predador, em fase imatura, variou de 70 a 100%. A joaninha apresentou período de oviposição de 47,3 e 51,7 dias, com 887,6 e 822,5 ovos, ao se alimentar de A. kuehniella e S. graminum, respectivamente. A longevidade das fêmeas foi de 74,1 e 76,2 dias e a dos machos de 67,3 e 70,3 dias, em A. kuehniella e S. graminum, respectivamente. H. axyridis atuou como predador intraguilda e foi a espécie dominante na competição com E. connexa.

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.

A biologia de Hippodamia convergens Guérin-Meneville foi estudada utilizando-se ovos de Anagasta kuehniella (Zeller) como alimento das larvas, em comparação com dieta comumente utilizada, constituída de adultos dos pulgões Schizaphis graminum (Rondani) e Brachycaudus (Appelia) schwartzi Börner. Para os adultos do predador, utilizaram-se adultos do pulgão S. graminum. Os experimentos foram conduzidos a 25 ± 1°C, UR de 70 ± 10% e fotofase de 12 h. O período embrionário, quando as larvas foram alimentadas com as três dietas foi de 3,1; 3,2 e 3,2 dias respectivamente. A duração do período de larva a adulto foi maior na dieta constituída de ovos de A. kuehniella (19,5 dias), entretanto a viabilidade para esse período não diferiu entre as três dietas testadas. Para a fase adulta do predador oriundo de larvas criadas sob os três regimes alimentares, todos os parâmetros reprodutivos e a longevidade foram estatisticamente iguais. Assim, verificou-se que ovos de A. kuehniella podem ser considerados uma dieta em potencial, em substituição aos pulgões S. graminum e B. schwartzi na criação de larvas de H. convergens.

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.

Natural enemies of the Class Insecta are important agents in the balance of aphid populations and an alternative to using insecticides to control these insects. The aim of this study was to identify the species of natural enemies associated with aphids present in peach orchards and observe the efficiency of capturing different sampling methods. The experiment was conducted from July, 2005 to September, 2006 in six peach orchards 'Chimarrita', in Araucária, PR, Brazil. The samples were taken by visual analysis in peach plants and weeds, yellow pan traps, sticky traps and funnels. Predator species were identified: Cryptolaemus montrouzieri, Cycloneda pulchella, Cycloneda sanguinea, Eriopis connexa, Harmonia axyridis, Hippodamia convergens and Scymnus sp. (Coleoptera, Coccinellidae), Allograpta sp., Palpada sp. and Toxomerus sp. (Diptera, Syrphidae) and Chrysoperla sp. (Neuroptera, Chrysopidae) and the parasitoids: Diaretiella rapae, Opius sp. and Praon sp (Braconidae). Examples of Encyrtidae and Eulophidae await identification. Chrysoperla sp. was a less abundant species. There were no statistically significant differences between the different sampling methods tested.

The objective of this work was to evaluate the development, survival, reproductive capacity, and longevity of the Asian ladybug Harmonia axyridis in comparison with Cycloneda sanguinea and Hippodamia convergens. Coccinellid larvae and adults were fed daily with Schizaphis graminum. Ten couples of each species were isolated for evaluation of the adult phase. The duration of the larval stage of H. axyridis is the longest (10.2 days) and its adults are the heaviest (29.7 mg) compared with C. sanguinea and H. convergens. The three species showed similar percentages of survival during the developmental stages. An average of 82% of C. sanguinea, H. axyridis, and H. convergens larvae reached adulthood, which indicates that temperature (25°C) and the offered prey are favorable to coccinellid development. Harmonia axyridis produces a higher total number of eggs per female (1,029.2) than the other evaluated species. However, H. axyridis, which lives for an average of 147.2 days, does not show a significantly greater longevity than C. sanguinea (87.2 days) and H. convergens (134.3 days).

Eriopis connexa (Germar) es un importante coccinélido afidófago distribuido en varios países de Sudamérica. Se estudió el impacto de la temperatura y alimentación sobre parámetros biológicos de sus estados inmaduros e imagos resultantes. Cohortes de larvas del coccinélido fueron criadas en una combinación de cuatro temperaturas constantes (9, 15, 19 y 27ºC) y 6 dietas de áfidos de las especies Acyrthosiphon pisum Harris y Schizaphis graminum (Rondani) con, respectivamente, cuatro y dos cantidades iniciales y tasas de incremento diarios. Las cantidades de huevos/postura y su viabilidad no fueron afectadas por las temperaturas superiores a 15ºC evaluadas. Los tiempos de incubación fueron desde 2,5 días y 92% de eclosión a 27ºC, hasta 13 días con una viabilidad del 71% a 15ºC. A 9ºC no se registraron oviposturas ni nacimientos aunque el desarrollo hasta adulto pudo ser completado en las cuatro temperaturas experimentales. La combinación de oferta de alimento y temperatura afectó tanto la ingesta de áfidos como los tiempos de desarrollo inmaduro, pero no las dimensiones de los adultos. Las cantidades totales de pulgones consumidos oscilaron aproximadamente entre 57 y 256 ninfas de A. pisum y desde 104 a 641 áfidos de la especie S. graminum. Los tiempos para el desarrollo, desde larva hasta adulto, fueron cercanos a 83,7 días a 9ºC hasta 11,8 días a 27ºC. Las mayores dimensiones de imagos se registraron a 19°C. El aumento del número de pulgones ofrecidos causó un incremento del peso corporal del adulto. El ancho del pronoto y la longitud del fémur del adulto fueron levemente influenciados por la especie presa pero sería relativamente independiente de la cantidad ingerida por las larvas.

Abstract 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 (2300cm3). 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.

Among the predatory ladybird beetles (Coccinellidae: Coleoptera), members of the Coccinellini, predators of aphids and psyllids, stand out. Although the beneficial status of these beetles has been acknowledged by biological control researchers, there are no keys or detailed studies on the immature stages of South American Coccinellidae, especially Coccinellini. We provide descriptions and illustrations of the immatures and adults of major predatory Coccinellini species in southern Brazil along with an identification key for fourth instar larvae and pupae. The following species are included: Cycloneda sanguinea (Linnaeus, 1763), Eriopis connexa (Germar, 1824), Harmonia axyridis (Pallas, 1773), Hippodamia convergens Guérin-Méneville, 1842 and Olla v-nigrum (Mulsant, 1866). The morphological study, which included the use of scanning electron microscopy, revealed new characters such as the type of tarsal claws, spiracles, chalazae, parascoli and strumae. The identification key provided here may be useful in biological control programs.
