AbstractThe antibiosis effect of gallic acid on Spodoptera litura F. (Lepidoptera: Noctuidae) and its parasitoid evaluated by feeding six days old larvae on artificial diet incorporated with different concentrations (5 ppm, 25 ppm, 125 ppm, 625 ppm, 3125 ppm) of the phenolic compound revealed higher concentration (LC50) of gallic acid had a negative impact on the survival and physiology of S. litura and its parasitoid Bracon hebetor (Say) (Hymenoptera:Braconidae). The mortality of S. litura larvae was increased whereas adult emergence declined with increasing concentration of gallic acid. The developmental period was delayed significantly and all the nutritional indices were reduced significantly with increase in concentration. Higher concentration (LC50) of gallic acid adversely affected egg hatching, larval mortality, adult emergence and total development period of B. hebetor. At lower concentration (LC30) the effect on B. hebetor adults and larvae was non-significant with respect to control. Gene expression for the enzymes viz., Superoxide dismutase, Glutathione peroxidase, Peroxidase, Esterases and Glutathione S transferases increased while the total hemocyte count of S. litura larvae decreased with treatment. Our findings suggest that gallic acid even at lower concentration (LC30) can impair the growth of S. litura larvae without causing any significant harm to its parasitoid B. hebetor and has immense potential to be used as biopesticides.

Considerable Damage

The safflower fly, Acanthiophilus helianthi Rossi, 1794 (Diptera: Tephritidae) is one of the most important pests of safflower in Iran. Losses caused by larval feeding leads to disrupted plant activities, reduction in flower buds, and, ultimately, to decreased quality and quantity of crop. An investigation was made from March 2008 to August 2009 in Gachsaran and Yasooj to record the pest status of safflower and their natural enemies. A total of twenty arthropods were recorded as pests of safflower. Out of 25 farms surveyed, only seven had the incidence of pest attack. Among the pests, Safflower fly and Silver ‐ Y‐ moth were found to cause considerable damage to the safflower plants, while others were not at economic levels. Among the natural enemies, parasitoids like Bracon hebetor, Bracon luteator, Colotrechnus viridis, Antistrophoplex conthurnatus, Microdontomenus annulatus, Ormyrus orientalis, Eurytoma acroptilae, Pronotalia carlinarum, Pteromalus sp. and Isocolus tinctorious were found to be associated with the pests of safflower.
