We found that leaf pubescence in Sassafras albidum (Nuttall) Nees negatively inßuences the growth and survivorship of a lepidopteran herbivore, Papilio troilus (L.). S. albidum leaves varied greatly in pubescence among plants. In laboratory choice experiments, P. troilus larvae preferred to eat and adult females preferred to oviposit on nonpubescent S. albidum leaves. Larvae fed pubescent S. al...

The bio-efficacy of endosulfan 0.07% with different quality of water as spray fluid was studied against different larval instars of Spodoptera. litura in laboratory condition. Among the four different quality of water, rain water and river water as spray fluid proved to be most effective while sea water as spray fluid resulted in low per cent mortality in different instars of S. litura, due to ...

The "good genes" hypothesis predicts that mating preferences enable females to select mates of superior genetic quality. The genetic consequences of the preference shown by female gray tree frogs for long-duration calls were evaluated by comparing the performance of maternal half-siblings sired by males with different call durations. Offspring of male gray tree frogs that produced long calls sh...

Background: Mosquitoes are responsible for the transmission of many pathogens and parasites and consequently serious diseases in humans. Currently, application of plant derivatives has been suggested as an alternative bio-control technique for these medically important vectors. Methods: In this study the essential oil and methanol extract of Achilleaw...

Barfin flounder larvae exhibit unique black coloration, as well as left-right asymmetry in juvenile stage as in other flatfish. In this study, we first assessed the changes in melanophores with development and then investigated their responsiveness to melanin-concentrating hormone (MCH) during metamorphosis. Larval-type melanophores appeared on both sides of the body before metamorphosis, where...

This study aimed to examine the effect of insecticide diazinon on hatchability fish eggs. The research method used a completely randomized design which included 4 treatments with 3 replications, namely P0 (control) P1 (0.4 ml/L), P2 (0.35 and P3 (0.3 ml/L). test parameters fecundity, egg hatchability, larval abnormalities, water quality. results showed that highest fecundity in this contained 1...
