The eVect of Wve diVerent food resources (Coccus hesperidum honeydew, honey-water, Lobularia maritima, Fagopyrum esculentum and water only) on the longevity, fecundity, and progeny Wtness of female Gonatocerus ashmeadi, an egg parasitoid of the glassy-winged sharpshooter (Homalodisca vitripennis) was investigated in the laboratory. Female G. ashmeadi survived 208–405% longer (up to 11.7 days lo...

Many insects face the challenge to select oviposition sites in heterogeneous environments where biotic and abiotic factors can change over time. One way to deal with this complexity is to use sensory experiences made during developmental stages to locate similar habitats or hosts in which larval development can be maximized. While various studies have investigated oviposition preference and lar...

In this study, susceptibility of the first three larval stages of Spodoptera exigua to Bacillus thuringiensis was investigated. To determine the LC50 values for each larval instar, 6 different logarithmic concentrations of Bacillus thuringiensis were used. A control was also included in each of the bioassays. The value of LC50 for 1st instar larvae, that had been treated one to four hours after...

Certain species of Hermetia illucens, also known as the Black Soldier Fly(BSF), were found in a compost plant in Roorkee located in Northern India. Its larvae arevoracious eaters of organic waste, hence can play an ecologically-important role in solidwaste management. Morphological analysis of various stages of BSF life cycle by SEMshowed that its body along with its wings is densely covered wi...

The purpose of this study was to address the importance of spiritual well-being and hope among cancer patients diagnosed with its different stages. Through stratified sampling techniques, 120 cancer patients from four stages evenly divided into male and female participated in this study. Spiritual Well-being Scale (Paloutzian & Ellison, 1982) and Hope Scale (Snyder, Harris, Anderson, et al, 199...

The polychaete Neanthes arenaceodentata- is cosmopolitan in distribution-, has been used as a laboratory test animal. Life history of this species has several unique features; the female dies after spawning and the male incubates the fertilized eggs through the 21-segmented stage. The larvae leave the tube and commence feeding. Changes in protein abundance and phosphorylation were examined duri...

Proper timing of the reproductive cycle to assure mate access is critical to optimizing success. We tested the importance of male presence on the progression of the female reproductive cycle in the blood python, Python curtus. Upon reaching sexual maturity, captive-born, individually raised virgin female snakes were housed with either a conspecific male or female. At the onset of the reproducti...

The present research which aimed at identifying the effects of astaxanthin pigment in upgrading efficiency in producing goldfish larvae through 4 treatments and 3 replications was conducted in the winter of 2014. For this reason, a sum of 12,4m3fiber glass fish ponds were prepared where in each, 50 female goldfish breeders were introduced with an average body weight of 47.21±2.19g. Then, 4 diet...

Event-related potentials were recorded from sleeping newborns to compare amplitudes and latencies of mismatch negativity (MMN) and late discriminative negativity (LDN) in active and quiet sleep stages. MMN and LDN were obtained in response to changes in semi-synthesized vowels from 20 healthy newborn infants. MMN and LDN responses were significant for both active and quiet sleep. The amplitude ...
