The cucumber moth, Diaphania indica (Saunders) (Lepidoptera: Pyralidae), is a tropical and sub-tropical cucurbits pest and a key greenhouse pest in the Jiroft region of Iran. In this study, the effect of different temperatures on the development of this pest was investigated on cucumber, Cucumis sativus L. (Cucurbitales: Cucurbitaceae), leaves in a growth chamber at various constant temperature...

Orthaga achatina Butler is an important pest of camphor trees in Asia. The complete mitochondrial genome O. was sequenced this study, which 15,150 bp size and comprised 13 protein-coding genes, 22 transfer RNA 2 ribosomal a control region. Besides, we used phylogenomic approach to infer evolutionary relationships 23 Lepidoptera species based on conserved protein sequences the genome. Our result...

The Chilo infuscatellus (Snellen; Lepidoptera: Pyralidae) is the main pest of sugarcane in China. The shortage of easily distinguishable morphological characters especially in early stage make it challenging to diagnosed and promptly take steps for pest management. In the present study, we described a PCR method for the molecular identification of based on barcode region of COI sequences betwee...

Through a joint SASEX/CIRAD, project the effect of Eldana saccharina Walker (Lepidoptera: Pyralidae) damage on stalk yield components was studied in fields at the SASEX farms at Gingindlovu and Empangeni. The formal experiment design consisted of randomised plots to compare natural infestation, artificial infestation and chemical treatments. Damaged stalks from infested plots had lower sucrose,...

Intraguild predation (IGP) is common in food web when two natural enemies share the same resources and prey. It may affect the success or failure of a biological control attempt. The role of intraguild predation by Geocoris ochropterus Fieber (Heteroptera: Geocoridae) on Trichogramma chilonis Ishii (Hymenoptera: Trichogrammatidae) developed on eggs of Helicoverpa armigera (Hubner) (Lepidoptera:...

DemographyofHabrobraconhebetor(Say)(Hymenoptera:Braconidae)on twopyralid host species [Galleria mellonella (L.) and Ephestia kuehniella Zeller] (Lepidoptera: Pyralidae) was studied at 28 C in the laboratory. Data were analyzed based on an age-stage, two-sex life table, to take both sexes and variable development into consideration. The intrinsic rate of increase (r), Þnite rate of increase ( ),...
