In this study, Angelica dahurica and Angelica pubescentis root essential oils were investigated as pest management perspectives, and root samples were also analyzed genetically using the nuclear ribosomal internal transcribed spacer (ITS) region as a DNA barcode marker. A. pubescentis root essential oil demonstrated weak antifungal activity against Colletotrichum acutatum, Colletotrichum fragar...

The Mediterranean sponges Aplysina aerophoba and A. cavernicola accumulate brominated isoxazoline alkaloids including aplysinamisin-1 (1), aerophobin-2 (2), isofistularin-3 (3) or aerothionin (4) at concentrations up to 10% of their respective dry weights. In laboratory feeding experiments employing the polyphagous Mediterranean fish Blennius sphinx crude extracts of both Aplysina sponges were ...

abstract confused flour beetle, tribolium confusum duval (col.: tenebrionidae) is one of the most important stored product pests of flour in iran. in this research the effects of insect growth regulators (igrs): teflubenzuron, hexaflumuron and pyriproxyfen were studied on larval and imago nutritional indices of confused flour beetle. the results showed that they were more effective on relative ...

BACKGROUND AND AIMS Mounting concerns about balancing food security with the environmental impacts of agro-chemical use underpin the need to better understand the mechanisms by which crop plants, particularly during the vulnerable seedling stage, attract or repel herbivores. METHODS The feeding preferences of the mollusc Helix aspersa were determined for several oilseed rape (Brassica napus) ...

microcerotermes diversus silvestri is the most economically destructive termite in structures in ahvaz (iran), and it consumes almost anything containing cellulose. this species lives in subterranean nests and gains access to buildings and vegetation by constructing underground galleries. because of their insecticidal activity, boron compounds may be beneficial for treating soil to create insec...

Economic losses due to bird damage to small fruits such as blueberries, grapes, and cherries can be very high and are expected to increase in the future. The primary sugars in these fruits are glucose and fructose. Sucrose is present in very low concentrations only. Our research has unveiled a physiological trait common to many fruit-eating species in the phylogenetically related families Musci...

mosquitoes is well known. As Hoffman and Miller comment, ‘We suggest a combination of directed wind and volatile repellent might be developed as a mosquito deterrent strategy for the backyard setting’ [3]. Indeed, the combination of DEET and permethrin in a coconut base (Mosbar) as a malaria control measure looks promising (M. Rowlands et al., unpublished). Volatile oils from plants can serve a...

BACKGROUND Exotic species have been hypothesized to successfully invade new habitats by virtue of possessing novel biochemistry that repels native enemies. Despite the pivotal long-term consequences of invasion for native food-webs, to date there are no experimental studies examining directly whether exotic plants are any more or less biochemically deterrent than native plants to native herbivo...
