The first record in Russia the Gallformed Midge – Asphondylia serpylli Kieffer (Diptera, Cecidomyiidae) on Thyme − Thymus serpyllum L. (Lamiaceae).

The effects of wild thyme (Thymus serpyllum L.) essential oil components against ochratoxin-producing Aspergilli.

The aim of this study was to determine the effects of the essential oil of Thymus serpyllum L. and of its components thymol and total phenols (total phenolic content, TPC) extracted from the plant on the growth and mycotoxin production of Aspergillus ochraceus, A. carbonarius, and A. niger. Minimal inhibitory concentration (MIC) determined for the essential oil and thymol, and selected concentr...

Within-Field Distribution of the Sunflower Midge (Diptera: Cecidomyiidae)

The sunßower midge, Contarinia schulzi Gagné (Diptera: Cecidomyiidae), is a pest of cultivated sunßower (Helianthus annuus L.). Larval feeding can cause damage and yield loss to the sunßower head. Adult emergence is extended and larvae are well protected in the sunßower receptacle, making chemical control methods difÞcult and expensive. Sunßower midge enter sunßower Þelds at the edges but Þeldw...

Saltbush-associated Asphondylia species (Diptera: Cecidomyiidae) in the Mediterranean Basin and their chalcidoid parasitoids (Hymenoptera: Chalcidoidea).

Numerous species of gall midges (Diptera: Cecidomyiidae) have been recorded from saltbush (Chenopodiaceae: Atriplex) around the world but only 11 of them belong to the large cecidomyiid genus Asphondylia. Of these, two species were described in the late 19th century from complex bud galls on Atriplex halimus in the Mediterranean Basin. In the present study Asphondylia punica is redescribed, A. ...

Thermal Requirements for Emergence of Overwintered Sorghum Midge (Diptera: Cecidomyiidae)

Seasonal Variation in Essential Oil Content and Composition of Thyme, Thymus serpyllum L. Cultivated in Uttarakhand Hills

Thymus serpyllum L. grown in Kumaon region of Western Himalaya was investigated for essential oil content and composition in different seasons. The oils of fresh samples were obtained by hydrodistillation. The yield of essential oil (% v/w) during different seasons varied from 0.07 to 0.28% with the highest in summer season, at vegetative stage. The oils were analyzed by GC and GC-MS. Major com...
