Insecticide resistance in natural enemies can be used as a positive trait in integrated pest management programs by increasing the compatibility of two important tools; biological and chemical control. In this experiment, a field population of Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) was selected with chlorantraniliprole for 35 generations (Chlor-Sel) developed a 100.32-fold resistance level compared to an unselected population (Unsel).

Tissue transglutaminase (TG2) is a multifunctional protein that can catalyze the cross-linking between proteins, and function as a G-protein. TG2's unregulated behaviour has been associated with fibrosis, celiac disease and cancer metastasis. Recently, small molecule irreversible inhibitors have been designed, bearing an electrophilic warhead that can react with the catalytic cysteine, abolishing TG2's catalytic and G-protein capabilities.

This study assessed and characterized its mode of inheritance, degree of dominance, realized heritability (h), and cross-resistance. Toxicity bioassays were performed on T.

The as-synthesized materials were morphologically and optically characterized using scanning electron microscopy (SEM), energy dispersive X-ray (EDX), X-ray diffraction (XRD), Fourier-transform infrared (FTIR), and ultraviolet-visible (UV-Vis) spectroscopy. The FTIR spectra clearly showed that two distinguishing bands at 603 and 674 cm of WO were shifted to a higher wavenumber upon doping with zirconium.

In order to use chemical and biological control in an integrated way, it is advantageous to know about natural enemy resistance response to a selected chemical. To determine C.
