the effect of temperature on demographic parameters of the greater wax moth, galleria mellonella (l.) was studied at 23, 25, 27, and 30 °c, 50 ± 10% rh and a photoperiod of 16:8 (l: d) h. the life table parameters were estimated according to the age-stage, two-sex life table procedure. in addition, the bootstrap technique was employed for estimating the means, variances, and standard errors of ...

this study describes the length-weight and length-length relationships for 28 populations of garra ruffa in different basins of iran, including tigris, karkheh, karun, persis and hormuz. the length-weight relationships from most localities are reported here for the first time. for most populations the b value was not significantly different from 3, indicating an isometric growth, in a few, it w...

We report on basic natural history, life history, and diet of Priapella chamulae (Poeciliidae) from Arroyo Tres, a small creek in Tabasco, southern México. The tertiary (adult) sex ratio was heavily female-skewed, female P. chamulae produced medium-sized offspring (~2.3 mg), one clutch at a time (i.e., showed no superfetation), and relied predominantly on yolk for embryo provisioning (Matrotrop...

trissolcus grandis (thomson) (hymenoptera: scelionidae) is the most important egg parasitoid of the common sunn pest, eurygaster integriceps puton (hemiptera: scutelleridae) in iran. demographic characteristics may be used for preliminary screening of parasitoid species or populations as well as for predicting their efficiency under different physical conditions in the field. in this study, the...
