Serpins are ubiquitously distributed serine protease inhibitors that covalently bind to target proteases to exert their activities. Serpins regulate a wide range of activities, particularly those in which protease-mediated cascades are active. The Drosophila melanogaster serpin Spn43Ac negatively controls the Toll pathway that is activated in response to fungal infection. The entomopathogenic f...

During a survey of entomopathogenic nematodes (EPNs) in the eastern Black Sea region of Turkey in 2009-2012, a steinernematid species was recorded and isolated using the Galleria-baiting method. The isolate was identified as Steinernema kraussei based on its morphological and molecular properties. The analysis of the ITS rDNA sequence placed the Turkish population of S. kraussei in the "feltiae...

Biological characteristics of two strains of the entomopathogenic nematode, Heterorhabditis floridensis (332 isolated in Florida and K22 isolated in Georgia) were described. The identity of the nematode's symbiotic bacteria was elucidated and found to be Photorhabdus luminescens subsp. luminescens. Beneficial traits pertinent to biocontrol (environmental tolerance and virulence) were characteri...

The peach fruit fly, Bactrocera zonata (Saunders) (Diptera: Tiphritidae), is an economic insect pest attacking the fruits of mangoes, apricots, guava, citrus, and peaches. This pest is difficult to be controlled by the traditional chemicals due to the behavior of its larvae that hide inside the fruits or its pupae that pupate in the soil. The present study documented the molecular identificatio...

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 ...

Indole-3-acetonitrile obtained from cabbage has been found to inhibit growth of Pyrausta nubilalis (Hbn.), Galleria mellonella (L.), and Penicillium chrysogenum.

EditoriAL Pathogens and their respective hosts interact closely leading to the host–pathogen framework response that could result in different outcomes that range from pathogen elimination to death of the host. To improve our ability to propose new measures that promote pathogen elimination and prevent host death, we need to have a comprehensive understanding of this interaction. Generally , mo...
