Attack intensity of Corythucha ciliata (Hemiptera, Tingidae) on Platanus spp. in an urban area in Portugal: a comparison between pruned and unpruned trees. IPB - Escola Superior Agrária
Gonçalves, Ana; Santos, Sónia A.P.; Pinto, M. Alice.
Corythucha ciliata (Say, 1832), commonly known as sycamore lace bug (SLB), is an insect species native to North America. Since its accidental introduction in Europe (through Italy) in 1964, it has expanded across most European countries. The arrival of SLB in Portugal is uncertain but its distribution is wide. Sycamore (Platanus spp.), the only host of SLB, is one of the most widespread and important urban tree species in Portugal. It provides a wide range of environmental, social and economical benefits, which have been threatened by the invasion of this pest. SLB damages trees by feeding on the underside of the leaves causing discoloration and eventually premature senescence. While the long-term effect of SLB on the health of urban trees is yet to be...

Biology of Corythucha gossypii Fabricius, 1794 (Hemiptera: Tingidae) in Ricinus communis at different temperatures and thermal requirements. Repositório Alice
OLIVEIRA, S. R.; SILVA, C. A. D. da; CARVALHO, T. S.; COSTA, L. A. A..
We studied the biology of Corythucha gossypii in Ricinus communis under different temperatures in climatic chambers adjusted at 20, 23, 25, and 28 °C, 60 ± 10% relative humidity, and a 12-h photoperiod. The development period and viability of eggs, the development period and survival rate of nymphs, and egg-adult cycle of C. gossypii as well as the adult longevity and fecundity were estimated. The thermal requirements (K) and temperature-base (Tb) were estimated for each of the immature stages and for the eggs-adults period. The duration of the eggs and nymphs phases and the egg-adult cycle of the C. gossypii on castor bean leaves at 20-28 °C were 7.6-17 days, 10.2-27.5 days, and 16.9-44.5 days, respectively. The lower temperature inhibited the oviposition...

Compared nymphal development of Tingis americana (Hemiptera, Tingidae) in two Handroanthus species (Bignoniaceae) and reproductive parameters in seedlings of Handroanthus heptaphyllus Iheringia, Sér. Zool.
Moreira,Daiane C.; Redaelli,Luiza R.; Guidoti,Marcus; Barcellos,Aline.
Nymphs and adults of Tingis americana Drake, 1922 were found feeding on leaves of Handroanthus heptaphyllus (Vell.) Mattos and Handroanthus chrysotrichus (Mart. ex A. DC.) Mattos in the Botanic Garden, Porto Alegre, state of Rio Grande do Sul, Brazil. This is the first record of T. americana on these host plants and in the southern Brazil. We aimed to compare the nymphal development on both hosts and to analyze the reproductive parameters on H. heptaphyllus (25 ± 1ºC; 60 ± 10% RH; 16 h photophase). The mean nymphal period (days) was shorter in individuals reared on H. heptaphyllus (12.69 ± 0.076) than on H. chrysotrichus (19.11 ± 0.208) (P < 0.0001), however, nymph viability was similar. On H. heptaphyllus, the mean embryonic period lasted 12.32 ± 0.274...

First report and morphological redescription of Teleonemia morio (Stål) (Hemiptera, Tingidae) in Annona squamosa L. (Annonaceae) in Brazil Rev. Bras. entomol.
Broglio,Sônia M. F.; Dias-Pini,Nivia da S.; Costa,Luiz A. A.; Lemos,Eurico E. P..
First report and morphological redescription of Teleonemia morio (Stål) (Hemiptera, Tingidae) in Annona squamosa L. (Annonaceae) in Brazil. This is the first report of a severe attack of Teleonemia morio (Stål, 1855) (Hemiptera, Heteroptera, Tingidae) on Annona squamosa L. (custard apple), causing up to 80% of losses of infested trees. In order to facilitate the identification of this insect pest, the adult female of T. morio is redescribed based on specimens collected in Palmeira dos Índios, Alagoas, Brazil.

Occurrence of lace bug Vatiga illudens and Vatiga manihotae (Hemiptera: Tingidae) in Mato Grosso do Sul, midwestern Brazil Anais da ABC (AABC)
Bellon,Patrícia P.; Wengrat,Ana P.G.S.; Kassab,Samir O.; Pietrowski,Vanda; Loureiro,Elisângela S..
Nymphs and adults of the lace bug (Hemiptera: Tingidae) have been found in cassava crops (Manihot esculenta) in Mato Grosso do Sul State, Brazil. The insects were collected in the field and taken to the laboratory where they were identified based on some morphological traits of the species Vatiga manihotae (Drake) and V. illudens (Drake), which are first reported in the aforementioned state.

The biological invasion of Corythucha ciliata (Hemiptera: Tingidae) in Portugal: an habitat modeling approach using a maximum-entropy technique IPB - Escola Superior Agrária
Pinto, M. Alice; Almeida, Mónica; Gonçalves, Ana; Santos, Sónia A.P.; Azevedo, João.
Corythucha ciliata is native to North America and has been introduced into Europe, through Italy, in 1964. Since then it has expanded across Europe being its date of arrival and distribution in Portugal unknown. This pest feeds on the underside of the leaves of sycamore trees (one of the most widespread ornamental tree in urban areas of Portugal) causing their premature senescence and death, in case of consecutive severe infestations. Habitat modeling is becoming an increasingly important tool for managing biological invasions, either prior or after the introduction of the invasive species. The models can be used to proactively assess the threat before introduction or, once the organism is introduced, to develop measures to stop or slow down dispersal. In...
