New host-plant records for the defoliator Ormiscodes amphimone (Fabricius) (Lepidoptera: Saturniidae).

Megalorhipida leucodactyla (Fabricius) (Lepidoptera: Pterophoridae): first distribution record from Chile and new host plant record.

The presence of Megalorhipida leucodactyla (Fabricius) (Lepidoptera: Pterophoridae) in Chile is reported for the first time from the Azapa valley, northern Chile. In this locality, some immature stages of M. leucodactyla were found to be associated with Tessaria absinthioides (Hook. & Arn.) DC., Asteraceae, a new host plant record at the species, genus and family level for M. leucodactyla.

Attraction of the gypsy moth to volatile organic compounds (VOCs) of damaged Dahurian larch.

Olfactory responses of the gypsy moth Lymantria dispar (L.) (Lepidoptera: Lymantriidae), a major defoliator of deciduous trees, were examined in Inner Mongolia, China. We studied whether the gypsy moth adults are attracted by the major volatile organic compounds (VOCs) of damaged Larix gmelinii (Dahurian larch) foliage and compared the attractiveness of the plant volatiles with that of the synt...

Extreme defoliation reduces tree growth but not C and N storage in a winter-deciduous species.

BACKGROUND AND AIMS There is a growing concern about how forests will respond to increased herbivory associated with climate change. Carbon (C) and nitrogen (N) limitation are hypothesized to cause decreasing growth after defoliation, and eventually mortality. This study examines the effects of a natural and massive defoliation by an insect on mature trees' C and N storage, which have rarely be...

Entomophthora syrphi, a new species of Entomophthorales for Iran

After heavy rainfalls in late Apr. of 2010 in Tehran, an epizootic occurred amongst hoverflies (Eupeodes corollae Fabricius) population in green spaces of Iranian Research Institute of Plant Protection, caused by an entomopathogenic fungus. Infected flies fixed to the upper parts of whitetop (Lepidium draba L.) and small tumbleweed mustard (Sisymbrium loeslii L.) plants with their proboscis and...
