Martins, Camila B. C.;Almeida, Lúcia M.;Zonta-de-Carvalho, Regina C.;Castro, Camila F.;Pereira, Rosylaine A.;
Revista Brasileira de Entomologia , 2009, DOI: 10.1590/S0085-56262009000400018
Abstract: harmonia axyridis (pallas) (coleoptera, coccinellidae) is a polyphagous asian species, well-known as a classical biological control agent of aphids around the world, introduced probably accidentally in brazil, sampled for the first time in 2002. it is an important intraguild predator, competing for food with native coccinellids. it was studied h. axyridis alimentary sources and host plants, its abundance compared with native and established species, the influence of abiotic factors and the seasons over the abundance of h. axyridis throughout one year, and discussed the mechanisms which influence the displacement of species. harmonia axyridis was found in 38 plant species, among them 20 were new records, feeding on 20 aphid species, eight of them new alimentary records. between 2006/2007, eight coccinellidae species were collected and h. axyridis was the most abundant (91.23%). harmonia axyridis peak of abundance occurred in august and september 2007, probably influenced by the temperature and food availability. from 1999 to 2007 a reduction and variation in the diversity of collected species of coccinellidae were observed with the predominance of h. axyridis, which may indicate their displacement.
Uma nova espécie do gênero Mesus Chevrolat do Mato Grosso do Sul, Brasil (Coleoptera, Carabidae, Scaritini)
Vieira, Letícia Maria;Bello, Ayr de Moura;
Revista Brasileira de Entomologia , 2004, DOI: 10.1590/S0085-56262004000200014
Abstract: a new species of the genus mesus chevrolat from mato grosso do sul, brazil (coleoptera, carabidae, scaritini). mesus pseudogigas sp. nov. is described based on two females (type locality: corumbá, mato grosso, brazil). the new species is very similar to m. gigas reichardt, 1974, mainly by the large size and by the lateral triangular expansion over the antennal insertions. figures of the new species and a key for the five known species of the genus are given.

Predation of Ladybird Beetles (Coleoptera: Coccinellidae) by Amphibians  [PDF]
John J. Sloggett
Insects , 2012, DOI: 10.3390/insects3030653
Abstract: Studies of predation of ladybird beetles (Coccinellidae) have focused on a limited number of predator taxa, such as birds and ants, while other potential predators have received limited attention. I here consider amphibians as predators of ladybirds. Published amphibian gut analyses show that ladybirds are quite often eaten by frogs and toads (Anura), with recorded frequencies reaching up to 15% of dietary items. Salamanders (Caudata) eat ladybirds less frequently, probably as their habits less often bring them into contact with the beetles. Amphibians do not appear to be deleteriously affected by the potentially toxic alkaloids that ladybirds possess. Amphibians, especially frogs and toads, use primarily prey movement as a release cue to attack their food; it is thus likely that their ability to discriminate against ladybirds and other chemically defended prey is limited. Because of this poor discriminatory power, amphibians have apparently evolved non-specific resistance to prey defensive chemicals, including ladybird alkaloids. Although amphibian-related ladybird mortality is limited, in certain habitats it could outweigh mortality from more frequently studied predators, notably birds. The gut analyses from the herpetological literature used in this study, suggest that in studying predation of insects, entomologists should consider specialized literature on other animal groups.
Incorporating a Sorghum Habitat for Enhancing Lady Beetles (Coleoptera: Coccinellidae) in Cotton
P. G. Tillman,T. E. Cottrell
Psyche , 2012, DOI: 10.1155/2012/150418
Abstract: Lady beetles (Coleoptera: Coccinellidae) prey on insect pests in cotton. The objective of this 2?yr on-farm study was to document the impact of a grain sorghum trap crop on the density of Coccinellidae on nearby cotton. Scymnus spp., Coccinella septempunctata (L.), Hippodamia convergens Guérin-Méneville, Harmonia axyridis (Pallas), Coleomegilla maculata (De Geer), Cycloneda munda (Say), and Olla v-nigrum (Mulsant) were found in sorghum over both years. Lady beetle compositions in sorghum and cotton and in yellow pyramidal traps were similar. For both years, density of lady beetles generally was higher on cotton with sorghum than on control cotton. Our results indicate that sorghum was a source of lady beetles in cotton, and thus incorporation of a sorghum habitat in farmscapes with cotton has great potential to enhance biocontrol of insect pests in cotton.
