“…In some insects such as Phenacoccus solenopsis and Spodoptera litura the detoxify indoxacarb were related with PMSO and EST enzymes activity while in C. rosaceana and L. botrana larvae, the PMSO, EST, and GST enzymes play an important role (Sayyed and Wright 2006;Sayyed et al 2008;Afzal andShad 2015 andHafez et al 2020).…”

Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae), is the most devastating insect pest that attacks potato crops in fields or storage. Pesticides are important to reduce population of this pest. The intent of this study was to investigate the sensitivity levels of P. operculella population field comparing with a reference to susceptible strain and biochemical analysis of technique(s) engaged in indoxacarb, sulfoxaflor and emamectin benzoate metabolism to 3 different detoxification enzymes (CPR-DPPH, GST-CDNB, and EST-PNPA). Resistance ratios were 11.9, 1.3 and 3.3 folds for indoxacarb, sulfoxaflor and emamectin benzoate, respectively in P. operculella field population. Biochemical analysis displayed that CYP450-DPPH and GST-CDNB activities show no a considerable (p<0.05) superfast compared with susceptible strain, furthermore, EST-PNPA activity showed a 2.7 fold increase compared to susceptible population. Bioassay analyses displayed moderate resistance to indoxacarb while a little resistance showed in at field population to emamectin benzoa of P. operculella. Esterases have a major role in the increase of resistance to indoxacarb, cytochrome P450 may have an elementary role in resistance against emamectin benzoate, GSTs do not apparently involve in the development of resistance against indoxacarb and emamectin benzoate of P. operculella. These results involved important practical application in managing pesticide resistance in P. operculella populations.

“…The development of waxy secretions protects the species from natural enemies (Franco et al, 2009). Chemical control has proved to be effective against the cotton mealybug El-Zahi et al, 2016), although moderate to high levels of resistance to several classes of insecticides have been developed (organophosphates, pyrethroids, avermectins, insect growth regulators, neonicotinoids) (Afzal & Shad, 2015;Ahmad & Akhtar, 2016;Saddiq et al, 2014Saddiq et al, , 2015Saddiq et al, , 2017.…”

Phenacoccus solenopsis Tinsley, 1898 (Hemiptera: Pseudococcidae), commonly known as the cotton mealybug or solenopsis mealybug, is a highly polyphagous species. This paper provides the first report of this species in Greece. It was detected in high numbers on tomato (Solanum lycopersicum) plants cultivated in a greenhouse in the region of Mirtos, close to the city of Ierapetra in the Southeast part of the island of Crete. The species identification was carried out using morphological and molecular analyses. The fact that P. solenopsis can be transferred easily via trade of live plant material, in combination with its ability to affect many different hosts causing severe damage, constitutes an increasing threat to Greek cultivation and especially to horticultural and vegetable crops. Additional surveys should be conducted to investigate the species distribution in Greece.

“…Since 2005, P. solenopsis has been recognized as posing a threat to ornamental plants, cotton, and vegetables. P. solenopsis affects in excess of 24 countries in Africa, Asia, Europe, and the Americas [22,23,24]. P. solenopsis secretes honeydew, which inhibits photosynthesis and produces sooty mold [25].…”

The quarantine insect pest Phenacoccus solenopsis (Hemiptera: Pseudococcidae) has a broad host range and is distributed worldwide. Each year, P. solenopsis causes significant crop losses. The detoxification of various xenobiotic compounds involves the cytochrome P450 monooxygenase (CYP) superfamily of enzymes. However, the functions of CYPs in P. solenopsis are poorly understood. In the present study, P. solenopsis was reared from the egg to the adult stage on three host plants: Tomato, cotton, and hibiscus. Thirty-seven P. solenopsis CYP genes were identified and their phylogenetic relationships were analyzed. Eleven CYP genes (PsCYP4NT1, PsCYP4G219, PsCYP6PZ1, PsCYP6PZ5, PsCYP301B1, PsCYP302A1, PsCYP305A22, PsCYP315A1, PsCYP353F1, PsCYP3634A1, and PsCYP3635A2) were selected for quantitative real-time PCR analysis. The results demonstrated marked differences in CYP expression levels in P. solenopsis grown on different host plants. The results will aid the molecular characterization of CYPs and will increase our understanding of CYP expression patterns in P. solenopsis during development and growth on different hosts.
