SUMMARYDespite treatment with praziquantel (PZQ) at 40 mg/kg in food, several chimpanzees on Ngamba Island Chimpanzee Sanctuary (NICS) continue to excrete eggs of Schistosoma mansoni. To monitor disease, 8 animals were closely examined under anaesthesia in March 2011 with portable ultrasonography and by rectal snip biopsy. Schistosome genetic diversity had been previously assayed within 4 of these chimpanzees, finding extensive diversity with 27 DNA barcodes encountered, although none was common to all animals. Calcified schistosome eggs were found in the rectal snips from 5 chimpanzees and liver fibrosis was clearly documented, indicative of progressive disease in 6 animals, the latter being surprisingly advanced in a younger chimpanzee. All 8 animals were treated under anaesthesia by oral gavage with PZQ at 60 mg/kg dosing that was well tolerated. These animals were again re-examined in June 2012 using stool and urine sampling. Only 1 chimpanzee appeared to be free from infection and active egg excretion was confirmed in 6 animals. If intestinal schistosomiasis is to be controlled within this setting, a long-term disease management plan is required which should combine active case-detection with an insistent treatment regime with praziquantel for these chimpanzees, exploring perhaps the performance of even higher dosing.

Dough Stage

Wheat grown in a growth chamber was infested at various stages of growth with adults of Say stink bug, Chlorochroa sayi Stål (Hemiptera:Pentatomidae). Feeding during the boot stage stunted the plants, and feeding just before heading reduced the numbers of kernels in the heads. Damage after heading varied directly with duration of feeding and numbers of insects but inversely with development of the kernels. Damage consisted of reduced numbers of kernels per head, lowered mean weights of kernels, or discolored kernels. Yield was reduced by more than 75% when wheat was fed upon just before, or 5 days after, the heads emerged. When the feeding occurred in the dough stage, damage was slight.

Abstract BackgroundBrown marmorated stink bug (BMSB), Halyomorpha halys (Hemiptera: Pentatomidae) is native to East Asia but has invaded many countries in the world. It is a polyphagous insect pest and causing significant economic losses to agriculture worldwide. Knowledge on the genetic diversity among BMSB populations is scarce but is essential to understand the patterns of colonization and invasion history of local populations. Efforts have been made to assess the genetic diversity of BMSB using partial mitochondrial DNA sequences but genetic divergence on mitochondria is not high enough to precisely identify and distinguish various BMSB populations. Therefore, in this study, we applied a ddRAD (double digest restriction-site associated DNA) sequencing approach to ascertain the genetic diversity of BMSB populations collected from 12 countries (2 native and 10 invaded) across four continents with the ultimate aim to trace the origin of BMSBs intercepted during border inspections and post-border surveillance.ResultA total of 1775 high confidence single nucleotide polymorphisms (SNPs) were identified from ddRAD sequencing data collected from 389 BMSB individuals. Principal component analysis (PCA) of the identified SNPs indicated the existence of two main distinct genetic clusters representing individuals sampled from regions where BMSB is native to, China and Japan, respectively, and one broad cluster comprised individuals sampled from countries which have been invaded by BMSB. The population genetic structure analysis further discriminated the genetic diversity among the BMSB populations at a higher resolution and distinguished them into five potential genetic clusters. ConclusionThe study revealed hidden genetic diversity among the studied BMSB populations across the continents. The BMSB populations from Japan were genetically distant from the other studied populations. Similarly, the BMSB populations from China were also separated from the Japanese and other populations. Further genetic structure analysis revealed the presence of at least three genetic clusters of BMSB in the invaded countries, possibly originating from multiple invasions. Furthermore, this study has produced novel set of SNP markers to enhance knowledge of genetic diversity among BMSB populations and demonstrate a great potential to trace the origin of BMSB individuals for future invasion events.

AbstractThis paper reviews the occurrence of the genus Chlorochroa Stål in Canada. It is shown that 10 species occur in this country, namely C. belfragii (Stål), C. faceta (Say), C. congrua Uhler, C. granulosa (Uhler), C. ligata (Say), C. opuntiae Esselbaugh, C. persimilis Horvath, C. rossiana Buxton and Thomas, C. uhleri (Stål), and C. viridicata (Walker). Chlorochroa sayi (Stål) does not occur in Canada. The published records of C. sayi as a pest of agricultural crops and ornamentals in Canada refer to C. uhleri.

Abstract. Meinita MDN, Akromah N, Andriyani N, Setijanto, Harwanto D, Liu T. 2021. Molecular identification of Gracilaria species (Gracilariales, Rhodophyta) obtained from the South Coast of Java Island, Indonesia. Biodiversitas 22: 3046-3056. The study of seaweeds diversity and species identification is an important component of marine resource management. However, seaweed identification based on morphological characteristics has several limitations. Besides, DNA barcodes or the partial sequences of cytochrome c oxidase I (COX1) have been proved to identify seaweeds at the species level. To date, Gracilaria species molecular diversity has not been studied in the South Coast of Java Island. Hence, this study aimed to identify the Gracilaria spp. obtained from 6 different beaches along the South Coast of Java, based on the COX1 gene. COX1 gene utilization for identifying and observing the genetic diversity, both intraspecific (genetic variation within species) and interspecific (variations between species) of Gracilaria species in this study has produced good results. A total of 13 seaweed samples collected from beaches in this study were identified as Gracilaria salicornia, G. edulis, G. firma, and G. textorii. The results of genetic diversity analysis conducted using the COX1 gene showed the intraspecific diversity of G. edulis obtained from the beaches of Kondang Merak, Kukup, Nusakambangan, and Karapyak was included in the moderate diversity category. Also, the intraspecific diversity of G. salicornia obtained from the beaches of Kondang Merak, Kukup, and Nusakambangan was included in the moderate diversity category, while the intraspecific diversity of G. textorii from Menganti and Karapyak Beach had no diversity.
