Diversity, Species Richness and Evenness of Moth Fauna of Peshawar
Moths were collected from different parts of Peshawar during June to August in 2007 to determine their diversity, species richness and evenness. A total number of 774 moth specimens were collected by using simple light traps operated from dusk to dawn daily for sixty nights. The moths caught were identified up to family level. Families Noctuidae, Pyralidae, Arctiidae, Geometridae, Sphingidae an...
متن کاملMEIOTIC STUDIES OF SOME AVENA SPECIES AND POPULATIONS IN IRAN
Eleven populations of five Avena species were analysed for meiotic characters including chiasma frequency and distribution as well as chromosomal association and segregation. Plants of a single population of A. eriantha showed the presence of 2n = 14 (diploid) and 2n = 4x = 28 chromosome number. Populations of A. barbata and A. wiestii possessed n = 14, while populations of A. sterilis ssp. lud...
متن کاملDeltamethrin resistance in some diamondback moth, Plutella xylostella populations in Iran
The diamondback moth, Plutella xylostella has been developed resistance to many groups of pesticides including of pyrethroids. The present study was conducted to evaluate the toxicity of deltamethrin on the third instar larvae of six populations of the pest using leaf dipping method. The results showed that different populations had different susceptibilities to deltamethrin. At the LC50 level,...
متن کاملDiversity, Species Richness and Evenness of Arctiidae and Geometriidae Moth Fauna of Barpeta and Cachar District
Moth species were studied from some selected districts of Assam (i.e., Cachar and Barpeta district) to determine their diversity index, species richness and evenness of Arctiidae and Geometriidae family of the moth fauna.The moths were collected by applying specialized trapping methods using UV light operating during night. Collected moth species were identified up to family-genusspecies level....
متن کاملSpecies richness and evenness in Australian birds.
Species richness and evenness are the two major components of biodiversity, but the way in which they are interrelated is a subject of contention. We found a negative relationship between the two variables for bird communities at 92 woodland sites across Australia and sought an explanation. Actual evapotranspiration (AET) was by far the best predictor of species richness. When AET was controlle...
