Crapemyrtle bark scale [CMBS (Acanthococcus lagerstroemiae)], a newly emerged pest in the United States, has spread to 16 U.S. states and unexpectedly spread on a native species american beautyberry (Callicarpa americana) in Texas and Louisiana in 2016 since it was initially reported on crapemyrtles (Lagerstroemia sp.) in Texas in 2004. The infestation of CMBS negatively impacted the flowering of crapemyrtles. We observed the infestation on the two most commercially available edible fig (Ficus carica) cultivars Beer’s Black and Chicago Hardy in a preliminary trial in 2018. To help estimate CMBS potential in aggravating risks to the ecosystem stability and the green industry, we conducted a host range and suitability test using ‘Bok Tower’ american beautyberry as a positive control with other eight beautyberry (Callicarpa) species [mexican beautyberry (C. acuminata), ‘Profusion’ bodinieri beautyberry (C. bodinieri), ‘Issai’ purple beautyberry (C. dichotoma), japanese beautyberry (C. japonica var. luxurians), ‘Alba’ white-fruited asian beautyberry (C. longissima), taiwan beautyberry (C. pilosissima), luanta beautyberry (C. randaiensis), and willow-leaf beautyberry (C. salicifolia)] and three fig (Ficus) species [creeping fig (F. pumila), roxburgh fig (F. auriculata), and waipahu fig (F. tikoua)] over 25 weeks. All the tested beautyberry species and waipahu fig sustainably supported the development and reproduction of nymphal CMBS and were confirmed as CMBS hosts. Furthermore, comparing with the control, mexican beautyberry, ‘Profusion’ bodinieri beautyberry, taiwan beautyberry, and willow-leaf beautyberry were significantly less suitable, while ‘Issai’ purple beautyberry, japanese beautyberry, ‘Alba’ white-fruited asian beautyberry, and luanta beautyberry were as suitable as ‘Bok Tower’ american beautyberry. Thus, when using beautyberries in landscapes, their different potential to host CMBS should be considered to minimize spreading CMBS through the native ecosystems.

The Chinese soft scale species in the genus Coccus Linnaeus, 1758 (Hemiptera: Coccomorpha: Coccidae) were studied. Coccus cambodiensis Takahashi and the Malaysian species C. cameronensis Takahashi are considered to be non-congeneric with Coccus hesperidum Linnaeus, 1758, the type species of Coccus, and are transferred to Prococcus Avasthi, 1993, as Prococcus cambodiensis (Takahashi, 1942), comb. n. and Prococcus cameronensis (Takahashi, 1952), comb. n. The generic diagnosis of Prococcus is revised. In the genus Coccus, two new species are described and illustrated based on adult females: Coccus nanningensis Cao & Feng, sp. n. from Guangxi, China, on Ficus carica (Moraceae), and Coccus cephalotaxus Cao & Feng, sp. n. from Shannxi, China, on Cephalotaxus sinensis (Taxaceae). Identification keys to separate adult females of Prococcus from Coccus, the 14 species of Coccus found in China, and all three species of Prococcus are provided.

Tyrosinase is a key enzyme in melanogenesis and its high activity leads to increasedpigmentations causing skin disorder like freckles, melanosoma and black spot. Therefore to search for new tyrosinase inhibitors is desirable. In present study, methanolic (MeOH) extracts from leaves, fruit peel and pulp of Citrus bergamia (CB) and, leaves and fruitof Ficus carica (FC) were prepared which were further process for fractional ethyl alcohol (EA), n-hexane (n-Hx) and chloroform (CHCl3)extractions (total 20 extracts) aiming to test their anti-tyrosinase potential, in-vitro. Our results confirmed that all MeOH FC and CB extracts showed significant anti-oxidant activity with IC50 range of 461.9 ± 16.1µg/ml to 2324.4 ± 116.1 µg/ml. Moreover, CB and FC all 20 extracts have significant anti-tyrosinase activity with IC50 range of 13.9 ± 0.5 µg/ml to 320.5 ± 3.3 µg/ml.  Interestingly, CB MeOH-EA peel and leaf extracts showed tyrosinase inhibition (IC50) 13.9 ± 0.5 µg/ml and 17.2 ± 0.8 µg/ml, respectively) is better than all other tested extracts and positive control kojic acid (IC50=18.75±5.29µg/ml). Thus, CB MeOH-EA peel extract with lowest IC50 value among all the tested extracts and kojic acid is proposed as potent candidate to control tyrosinase rooted hyperpigmentation.
