In-vivo measurement of the fluorescence spectrum of wild cochineal (Dactylopius opuntiae)

Abstract It is known that the harmful presence of the wild cochineal (Dactylopius opuntiae), unlike the fine cochineal (Dactylopius coccus), in prickly pear crops of farmers leads to consider it as one of the major pests for this crop. In this study, we present the implementation of an optical setup...
