A new species of Eupithecia Curtis (Lepidoptera, Geometridae) from the Azapa Valley, northern Chile

A new species of Eupithecia Curtis (Lepidoptera, Geometridae) from the Azapa Valley, northern Chile. Male and female adults of a new species of Eupithecia Curtis from the Arica Province, Chile are described and illustrated. The species is compared with E. yubitzae Vargas & Parra, 2004, from the same locality, and E. galapagosata Landry & Rindge 1995, from the Galapagos Islands, Ecuador.

First record of folivory on a newly documented host plant for the little known geometrid moth Eupithecia yubitzae Vargas & Parra (Lepidoptera, Geometridae) in northern Chile

The native tree Schinus molle (Anacardiacae) is reported for the first time as a host plant for larvae of the little known geometrid moth Eupithecia yubitzae Vargas & Parra (Lepidoptera, Geometridae) in the Atacama Desert of northern Chile, based on morphology and DNA barcodes. This discovery importantly expands the host range of E. yubitzae, as previous records were restricted to Fabaceae trees. Larvae were previously known as florivorous, while these were found to be folivorous on S. molle. Furthermore, host-associated cryptic larval polychromatism was detected, as larvae collected on S. molle were found to be mostly pale green, contrasting with the dark yellow ground color of the larvae typically collected on fabaceous host plants.

Observações preliminares sobre a malformação em inflorescencias de mangueira (Mangifera indica L.) e fungo, alguns insetos e ácaro nelas encontrados

A malformação de inflorescências e o superbrotamento de gemas terminais e axilares de mangueiras dos Estados de São Paulo e Pernambuco são relacionados com o ácaro Aceria mangiferae Sayed, 1946 (Acarina, Eriophyidae) e o fungo Fusarium moniliforme subglutinans, sendo êste último considerado, empíricamente, como o principal agente causal da doença. Varios insetos associados às inflorescências de mangueiras foram coletados: lagarta de Eupithecia sp. (Tephroclystis), (Lepidoptera, Geometriidae, Hydriomeninae); Frankliniella cubensis Hood, 1925 (Thysanoptera, Thripidae); coleopteros pertencentes às familias Nitidulidae e Cryptophagidae.
