selectivity of mycoinsecticides and a pyrethroid to the egg parasitoid cleruchoides noackae hymenoptera mymaridae
Scientific Reports, 2020Co-Authors: Mauricio Magalhaes Domingues, A. R. De ,souza, L K Becchi, Simone Graziele Moio Velozo, Leonardo Rodrigues Barbosa, Marcus Alvarenga Soares, Jose Eduardo Serrao, Jose Cola Zanuncio, Carlos Frederico WilckenAbstract:Plants of the genus Eucalyptus, cultivated in many countries, have great importance for the world economy. In Brazil, this culture occupies a total of 5.7 million hectares, but native and exotic insect pests can reduce its productivity. Thaumastocoris Peregrinus Carpintero & Dellape (Hemiptera: Thaumastocoridae), an exotic Australian pest, damages Eucalyptus plants. Biological control using the egg parasitoid Cleruchoides noackae Lin & Huber (Hymenoptera: Mymaridae), Heteroptera predators and entomopathogenic fungi, such as Beauveria bassiana and Metarhizium anisopliae, have potential for managing T. Peregrinus. Chemical insecticides, including bifenthrin and acetamiprid + bifenthrin, also control this insect. The compatibility of chemical and biological control methods favors integrated pest management. The objective of this study was to evaluate the selectivity of commercial products based on B. bassiana, M. anisopliae and the chemical bifenthrin on the parasitoid C. noackae and its parasitism on T. Peregrinus eggs. The selectivity test followed the standards recommended by the International Organization for Biological Control (IOBC). Beauveria bassiana has selectivity to parasitism as well as viability, but was slightly harmful to C. noackae adults; M. anisopliae was innocuous to adults and to the viability of the offspring of this parasitoid, but it reduced the parasitism rate; and bifenthrin did not show selectivity to this parasitoid.

biological parameters life table and thermal requirements of thaumastocoris Peregrinus heteroptera thaumastocoridae at different temperatures
Scientific Reports, 2019Co-Authors: Leonardo Rodrigues Barbosa, Carlos Frederico Wilcken, Everton Pires Soliman, Antonio Jose Vinha Zanuncio, F Santos, A P Rodrigues, Juliana Mendonca Campos, Jose Cola ZanuncioAbstract:Temperature affects the development, population dynamics, reproduction and population size of insects. Thaumastocoris Peregrinus Carpintero et Dellape (Heteroptera: Thaumastocoridae) is a eucalyptus pest. The objective of this study was to determine biological and life table parameters of T. Peregrinus on Eucalyptus benthamii at five temperatures (18 °C; 22 °C; 25 °C; 27 °C and 30 °C) with a relative humidity (RH) of 70 ± 10% and photoperiod of 12 hours. The duration of each instar and the longevity of this insect were inversely proportional to the temperature, regardless of sex. The nymph stage of T. Peregrinus was 36.4 days at 18 °C and 16.1 days at 30 °C. The pre-oviposition period was 5.1 days at 30 °C and 13.1 days at 18 °C and that of oviposition was 7.6 days at 30 °C and 51.2 days at 22 °C. The generation time (T) of T. Peregrinus was 27.11 days at 22 °C and 8.22 days at 30 °C. Lower temperatures reduced the development and increased the life stage duration of T. Peregrinus. Optimum temperatures for T. Peregrinus development and reproduction were 18 and 25 °C, respectively.

chemical vs entomopathogenic control of thaumastocoris Peregrinus hemiptera thaumastocoridae via aerial application in eucalyptus plantations
Scientific Reports, 2019Co-Authors: Carlos Frederico Wilcken, Leonardo Rodrigues Barbosa, Mario Henrique Ferreira Do Amaral Dal Pogetto, A C V Lima, Everton Pires Soliman, Bianca Vique Fernandes, Isabel Silva, Antonio Jose Vinha Zanuncio, Jose Cola ZanuncioAbstract:The Thaumastocoris Peregrinus spread to eucalyptus plantations in many countries. Chemical control is a questionable measure, mainly due to the environmental impact, high cost and moreover has the use restricted by the forest certifications. Bio-insecticides may have similar efficiency to chemical products to control T. Peregrinus. The chemical thiamethoxam, thiamethoxam + lambda-cyhalothrin, acephate and the microbial Beauveria bassiana and Metarhizium anisopliae insecticides were tested at different doses to manage T. Peregrinus. The products were sprayed on eucalyptus plants using aircraft and populations of this insect were counted before application and at 1, 14 and 21 days afterwards (DAA). Ten eucalyptus trees were evaluated per plot, with the collection of ten leaves from the middle third of the crown of each tree, and the number of T. Peregrinus nymphs and adults obtained per leaf was determined. All the chemical insecticides had similar control at 1 DAA for T. Peregrinus nymphs and adults. At 14 DAA, the number of T. Peregrinus nymphs and adults on eucalyptus leaves was similar for the chemical and microbial insecticide treatments. At 21 DAA the control efficiency of T. Peregrinus nymphs and adults was higher than 80% with all insecticides. The entomopathogenic insecticides have potential for aerial application to control T. Peregrinus nymphs and adults and provide viable and environmentally-friendly alternative to manage this pest.

The parasitism and development of C. noackae was studied in T. Peregrinus eggs of different ages, laid on eucalyptus leaves or paper towel and stored at 5 °C. The emergence, sex ratio and development of C. noackae and hatched nymphs of T. Peregrinus were evaluated. This parasitoid had an emergence rate higher than 60% from zero to one, one to two, and two to three-day old eggs and lower than 10% for those 3–4 and 4–5 days old. The female proportion was 78% and the egg-adult period for C. noackae was 19.5 days. The use of T. Peregrinus eggs up to three days old, laid on paper towel and stored at 5 °C for 14 days did not affect the biological parameters of C. nockae and should be used for mass rearing of this parasitoid.

biology of thaumastocoris Peregrinus in different eucalyptus species and hybrids
Phytoparasitica, 2012Co-Authors: Everton Pires Soliman, Carlos Frederico Wilcken, Mario Henrique Ferreira Do Amaral Dal Pogetto, Thaíse Karla Ribeiro Dias, Jaqueline Magalhaes Pereira, Bruno Zache, Leonardo Rodrigues BarbosaAbstract:The bronze bug Thaumastocoris Peregrinus Carpintero & Dellape (Hemiptera: Thaumastocoridae), originating in Australia, has been rapidly spreading in eucalyptus plantations in the Southern Hemisphere, including South Africa, Zimbabwe, Argentina, Uruguay, Paraguay and Chile. In Brazil, it was detected in 2008 in the states of Sao Paulo and Rio Grande do Sul. Due to incomplete knowledge about the biology of this pest, the present study evaluated the bioecology of T. Peregrinus in different eucalyptus species and hybrids. The genetic materials utilized were: Eucalyptus camaldulensis, E. urophylla, E. grandis, ‘1277’ (Hybrid E. grandis x camaldulensis—HGC), ‘VM-1’ (Hybrid E. urophylla x camaldulensis—HUC) and ‘H-13’ (Hybrid E. urophylla x grandis—HUG). The experiment was conducted in a climate-controlled chamber at a temperature of 26 ± 1°C, r.h. = 70% ± 10% and 12 h photophase. The biology of different genotypes indicated that the species E. urophylla and E. grandis are the most suitable for the development and reproduction of T. Peregrinus, although all treatments enabled the bronze bug to develop and produce descendants. T. Peregrinus developed and reproduced in the principal vegetal materials planted in the southern, central-west and northeastern regions of Brazil, constituting a potentially damaging insect pest to eucalyptus plantations.

the potential global distribution of the bronze bug thaumastocoris Peregrinus carpintero and dellape hemiptera thaumastocoridae
Agricultural and Forest Entomology, 2015Co-Authors: Maria C Saavedra, Gonzalo A Avila, T M Withers, Gregory I HolwellAbstract:Thaumastocoris Peregrinus is a sap-feeding insect native to Australia that has become a serious global pest of Eucalyptus species. To date, T. Peregrinus has been found in more than 10 countries across Europe, Africa, South America and Oceania. In the present study, we used the climate modelling software climex (Hearne Scientific Software Pty Ltd, Australia) to predict the potential distribution of T. Peregrinus globally and in New Zealand. climex parameters were based on experimental data obtained in the present study and from records collated from the insect's native and invasive distribution. The model of the potential native geographical distribution closely agrees with the known distribution of T. Peregrinus and predicts potential expansion into more tropical areas of Australia. In New Zealand, the predicted potential distribution of T. Peregrinus matches its current distribution and predicts that, if a suitable host is present, the species will be able to establish in most of the North Island and in northern and eastern regions of the South Island. Globally, the model predicts that many of the world's temperate, Mediterranean and subtropical areas are climatically suitable for establishment of T. Peregrinus. This predicted distribution closely matches the global distribution of eucalypt plantations, which are essential for the establishment of this pest. climex projections of potential suitability for T. Peregrinus reported in the present study may prove useful for risk assessments and for the identification of areas susceptible to invasion by this pest.

susceptibility of four eucalyptus host species for the development of thaumastocoris Peregrinus carpintero and dellape hemiptera thaumastocoridae
Forest Ecology and Management, 2015Co-Authors: Maria C Saavedra, T M Withers, Gregory I HolwellAbstract:Abstract Thaumastocoris Peregrinus is a serious sap-sucking pest of Eucalyptus species in many important forest growing regions worldwide. This invasive insect may not only cause enormous economic losses to the eucalypt forest industry but also negatively affect urban trees in public spaces. We conducted laboratory experiments to evaluate the susceptibility of four Eucalyptus species for the development of T. Peregrinus . Three of the tested Eucalyptus species are economically important for the forestry industry worldwide and the other is a popular amenity tree in New Zealand. The development of eggs, nymphs and adults was evaluated in excised leaf assays. Eucalyptus nitens and Eucalyptus nicholii were identified as suitable host plants. The adult leaf type of E. nitens was shown to be critical for successful feeding. Despite initiating feeding T. Peregrinus did not survive beyond 1st instar nymph on either Eucalyptus fastigata or Eucalyptus regnans . Accordingly, our study contributes evidence that there may be a lower risk to species within the subgenus Monocalyptus from T. Peregrinus damage . These are positive findings for the forestry sector as E. regnans and E. fastigata are both valued Eucalyptus species grown predominantly for pulp in commercial forestry in New Zealand and worldwide.
