demographic parameters of the pink stem borer, sesamia creticalederer (lepidoptera: noctuidae) were estimatedon its two main host plants, maize and sugarcane. the present studywas conducted under laboratory conditions at 27±1˚c, 50±10% relative humidity (rh %), and a photoperiod of 0:24 (l:d) hour for the larval stage and 16:8 (l:d) hour for the other life stages. the raw data were analyzed bas...

predatory damsel bug, nabis pseudoferus remane has a high density in the alfalfa fields and feeds on different types of prey. in this study, biological properties and life table statistics of n. pseudoferus by feeding on melon aphids have been determined under controlled conditions (at 25±1˚c, 60±10% relative humidity and under a photoperiod of 16h light/ 8h dark). data analysis carried out bas...

aphis gossypii glover is one of the most important pests of greenhouse cucumber and pepper in the world and iran. in this research, life table and biology of a. gossypii were investigated on cucumber (cucumis sativus cv. super sultan) and pepper (capsicum annum cv. marqueza) in a growth chamber at 25±1°c and 60±5% rh and a photoperiod of 14 l: 10 d hour.the results showed thatdevelopmental time...

the greenhouse whitefly, trialeurodes vaporariorum westwood (hem.: aleyrodidae) is a polyphagous and key pest that causes damaging to wide range of crops. the parasitoid wasp, eretmocerus delhiensis mani (hym.: aphelinidae) is a syn-ovigenic and thelytokous species that parasitizing greenhouse whitefly nymphs. in order to evaluation parasitoid wasp, eretmocerus delhiensis mani (hym.: aphelinida...

this paper demonstrates a preliminary investigation of geometry, function and its relation to dfx principles, namely dfm (design for manufacturing). this is the starting point for research on the development of an expert system that assesses design goals along dfx principles in a feature-based cad environment. there is a need for a deeper level of understanding of the relationship between geome...
