Resumo. O presente estudo teve como objetivos avaliar a resposta funcional dos instares larvais e adultos de três espécies de coccinelídeos predadores [Harmonia axyridis (Pallas), Cycloneda sanguinea (Linnaeus) e Hippodamia convergens Guerin Meneville] em diferentes densidades de Brevicoryne brassicae (Linnaeus), comparando o desempenho da espécie invasora com as espécies locais. Observou-se que H. axyridis consumiu mais insetos que as outras espécies; o número de pulgões predados pelas três espécies de coccinelídeos aumentou com a troca do instares larvais e, que as fêmeas tenderam a predar mais pulgões que os machos. A voracidade das larvas de 4º instar é similar a dos adultos, às vezes até maior, como no caso da C. sanguinea. Exceto no 1º instar larval, todos os outros estágios de vida mostraram aumento do consumo de pulgões à medida que a oferta de presas aumenta. Os resultados mostraram que a resposta funcional do tipo III foi indicada apenas pelas larvas de 3º instar de H. axyridis e nas demais espécies e estágios avaliados a resposta funcional foi do tipo II. Em geral H. axyridis apresentou assíntotas das respostas funcionais mais elevadas em comparação com as espécies anteriormente estabelecidas. Entretanto, a diferença entre a magnitude das curvas de respostas funcionais entre a invasora e as espécies locais não é muito acentuada, o que pode indicar pouco impacto da invasora sobre a população de recursos no campo e, uma tendência a adaptação e estabilização entre estas espécies da comunidade intraguilda.Functional response compared between Harmonia axyridis (Pallas), Cycloneda sanguinea (Linnaeus) and Hippodamia convergens Guerin Meneville (Coleoptera: Coccinellidae) fed on Brevicoryne brassicae (Linnaeus) (Hemiptera: Aphididae)Abstract. The study evaluated the functional response of larval instars and adult of three species of coccinellids predator [Harmonia axyridis (Pallas), Cycloneda sanguinea (Linnaeus) and Hippodamia convergens Guerin Meneville] in different densities of Brevicoryne brassicae (Linnaeus), comparing the performance of the invasive species with the local species. It was observed that H. axyridis consumed more insects than the other species; the number of aphids preyed by the three species of coccinellids increased with the exchange of larval instars and that females tended to prey more aphids than males. The voracity of the 4th instar larvae is similar to that of adults, sometimes even larger, as in the case of C. sanguinea. Except for the first larval instar, all other stages of life have shown increased aphid consumption as the supply of prey increases. The results showed that the functional response of type III was indicated only by the 3rd instar larvae of H. axyridis and in the other species and stages evaluated the functional response was type II. In general H. axyridis presented asymptotes of the highest functional responses in comparison to the previously established species. However, the difference between the magnitude of the functional response curves between the invasive and the local species is not very pronounced, which may indicate little impact of the invasive on the population of resources in the field and a tendency to adaptation and stabilization between these species of the intraguild community.

Harmonia Axyridis Pallas

The multicolored Asian lady beetle, Harmonia axyridis (Pallas, 1773), was first recorded in Brazil in 2002 in Paraná state and subsequently observed in Santa Catarina, Rio Grande do Sul and Minas Gerais. This species can spread to new areas and become dominant in the local community, reducing the density and diversity of native species, mainly Coccinellidae. The objective of this work was to record for the first time the occurrence of H. axyridis in the Federal District and its co-occurrence with other Coccinellidae species. The individuals were collected directly from plants at an organic farm in Taguatinga and in experimental fields of Embrapa Hortaliças, located in the Federal District, from August 2008 to January 2010. We collected 881 Coccinelids, and of these, 110 belong to the species H. axyridis. These were found exclusively on the following plants of the succinea group: maize, cabbage, cauliflower, broccoli, kale, cucumber, cotton, tomato and coriander. We also observed its co-occurrence with the following lady beetle species: Cycloneda sanguine (Linnaeus, 1763), Hippodamia convergens (Guerin-Meneville 1842), Eriopis connexa (German, 1824), Scymnus sp., Nephaspis sp., Azya luteipes (Mulsant, 1850), Hyperaspis festiva (Mulsant, 1850), Olla v-nigrum (Mulsant, 1866), Psyllobora sp. and Coleomegilla maculata (De Geer, 1775). So far, we have not found any negative interactions between H. axyridis and these species. This is the northernmost H. axyridis record in Brazil. Moreover, the region was previously considered to have a low probability of occurrence for this species. Therefore, this record confirms that H. axyridis presents great adaptive plasticity to new habitats.

Field tests were conducted to determine if, at the conclusion of their autumn migratory flight, Harmonia axyridis (Pallas) are attracted to and preferentially alight on targets covered with the printed images of lady beetles. There was no significant difference in the number of beetles that landed on targets bearing depictions of coccinellids compared with the number that landed on blank, white controls. Results suggest that commercial traps that rely on images of lady beetles to attract incoming coccinellids are of little practical value.

Significant Mortality

Susceptibility of three predatory arthropods namely Asian lady beetle, Harmonia axyridis (Pallas), lynx spider, Lycosa pseudoannulata (Boescriberg and Strand), and wolf spider, Oxyopes javanus (Thorell) to four commonly used biorational molecules viz. buprofezin, spinosad, emamectin benzoate and abamectin were determined in a brinjal ecosystem. Biorational pesticides were applied singly and in some selected combinations and their toxicity on the predators was recorded up to three sprayings in a confined habitat. Buprofezin caused no significant mortality of predators (2.87%, 0.32%, 0.96% mean mortality per spray of Asian lady beetle, lynx spider, and wolf spider respectively) and was found most compatible among the biorational molecules. However, other three tested molecules were found highly toxic for all predatory natural enemies when applied singly or in combination with buprofezin. Spinosad was most toxic for Asian lady beetles (21.84% mean mortality per spray) and lynx spiders (15.32 % mean mortality per spray) whereas abamectin (17.78% mean mortality per spray) for wolf spiders. It was observed that the number of spraying was very crucial and had a proportionate relationship with the mortality percentage of predators. Based on this study it is suggested that buprofezin could be considered to incorporate safely in the IPM program for brinjal pest management.J. Bangladesh Agril. Univ. 15(2): 234-238, December 2017
