Abstract Two distinct morphologies of Cymothoidae isopod, Lobothorax typus were collected from the marine water of Bay of Bengal, Goapalpur-on-Sea as the first record of this parasite from coastal water of Odisha, India. All specimens were found attached to the buccal region of different individuals of the same host fish Trichiurus lepturus. With the aid of COI gene sequencing and morphological analysis, the individuals were found to be conspecific. The most prominent variation among the two morphologies includes the size of 5th pereonite and pleon length to total body length ratio. These variations are as a result of the biphasic moulting process. Maximum Likelihood (ML) tree analysis based on COI gene sequences concluded the monophyletic taxonomy of different buccal attaching genera under the family Cymothoidae which is in congruence with their morphological divergence.

A new quill mite species, Syringophilopsis bochkovi sp. n. (Acariformes: Syringophilidae), is described from two species of manakins (Passeriformes: Pipridae), Corapipo altera (type host) and Manacus vitellinus collected in Panama. Females of the new species differ from those of morphologically similar S. nitens Skoracki et Dabert, 2001 by the following features: the total body length is 960–1,010 µm (vs. 1,265–1,285 µm in S. nitens); the dorsal shields (propodonotal, hysteronotal and pygidial) and coxal fields I–IV are apunctate (vs. all these sclerites are punctate); each lateral branch of the peritremes has 11 chambers (vs. 13 chambers); and the lengths of dorsal idiosomal setae d2 and e2 are 330–350 and 330–370 µm, respectively (vs. 390–400 and 420–460 µm). Syringophilopsis bochkovi represents the first record of the family Syringophilidae on passerines of the family Pipridae.

Mixed Infestation

The current study was conducted in 28 farms from 11 administrative districts in Bulgaria and included 4132 goats from six breeds, naturally infested with ectoparasitic insects. The visit to the farms was paid after the owners alarmed for signs of strong discomfort and itching among the animals. From the 28 studied herds, 14 (50%) turned out to be infested with the African sucking louse of goats: Linognathus africanus (Kellog & Paine, 1911) belonging to the family Linognathidae, suborder Anoplura, order Phthiraptera. All documented cases were of mixed infestation with other ectoparasitic species. The ectoparasites were collected and preserved in 70o ethanol for laboratory identification, morphological observation and for preparing photographic material. The full morphological description of the species showed that the total body length (TBL) of the male individuals varied between 0.912-1.556 mm, and that of the females: from 1.159 to 1.784 mm. A morphological identificationof the phylogenetically close species Linognathus africanus (Kellog & Paine, 1911) and Linognathus stenopsis (Burmeister, 1838) was conducted in laboratory conditions. The population structure of the species was presented through the sex identification of Linognathus africanus which demonstrated a numerical ratio of F:M = 2.2:1.

Abstract The present study report the parasitic isopod infection on commercial fishes of the northern part of the east coast of India collected during the period 2010-2015 from the marine water of Odisha and West Bengal. During the study, 394 isopods were collected after examining 2668 fishes. These include 14 species of isopods, out of which 13 belong to 5 genera under the family Cymothoidae, and a single species Alitropus typus belongs to the family: Aegidae. Of theses, 03 species viz., Catoessa boscii, Cymothoa eremita and Nerocila loveni are first record to the northern part of east coast of India. Out of the 2668 fishes examined, 326 examples belonging to 34 species under 19 different families were infected by different isopods. Member of the host fish family Carangidae was more parasitized by isopods, followed by Clupeidae, Scoberidae, and Leiognathidae. The dominant isopods were Nerocila phaiopleura and Catoessa boschii. The total prevalence was 12.21. The prevalence was high on the host fish Alepes djedaba and lowest on Lutjanus johnii. The total infection caused by genus Alitropus was 1.52%, Anilocra was 5.07%, Catoessa was 24.87%, Cymothoa was 0.25%, Nerocila was 65.73%, and Norileca was 2.55%. The isopod prevention was high during the post-monsoon and low during the monsoon period.

Herein two new species of the genusSyngastesMonard, 1924 are described from South Korea, with detailed descriptions and illustrations. Both new copepods,Syngastesmulticavussp. nov. andS. pseudofoveatussp. nov., have two inner setae on the first exopodal segment of P2 and P3.Syngastesmulticavussp. nov. most closely resemblesS. gibbosusBartsch, 1999 reported from Australia, as they both have a five-segmented antennule in the female. However,Syngastesmulticavussp. nov. has a rounded body outline instead of the gibbose outline observed inS. gibbosus.Syngastespseudofoveatussp. nov. resemblesS. foveatusBartsch, 1994 in almost all aspects. However, they differ clearly in the number of setae on the first exopodal segment of P2 and P3. We also provide a key to species of the genusSyngastesworldwide. The present study is the first record of the family Tegastidae in Korean waters.

The tapeta lucida of three species of teleosts were examined to determine the composition of the reflecting material. The fishes were bay anchovy Anchoa mitchilli (Engraulidae), gizzard shad Dorosoma cepedianum (Clupeidae) and pigfish Orthopristes chrysopterus (Haemulidae). The tapetum of each species was situated in the pigment epithelium of the eye. That of the pigfish contained triglycerides identified as chiefly glyceryl tridocosahexaenoate. A reduced pteridine, 7, 8-dihydroxanthopterin, occurred in the tapetum of the gizzard shad. Guanine occurred in the tapetum of the bay anchovy. The tapetum of the shad contained brightly reflecting particles about 0.5 μm in diameter There were 10.8 mg of dihydroxanthopterin in the tapetum of a shad (total body length 23 cm) and 0.46 mg of guanine in the tapetum of an anchovy (total body length 9 cm). This is the first report of a pteridine acting as a retinal reflector in vertebrates. Various aspects of retinal reflectors of teleosts are discussed and their variety and common characteristics commented upon.

The genetic structure of field populations of begomoviruses and their whitefly vector Bemisia tabaci in Pakistan was analyzed. Begomoviruses and B. tabaci populations were sampled from different crops and weeds in different locations in Punjab and Sindh provinces, in areas where cotton leaf curl disease (CLCuD) occurs or does not occur. Phylogenetic analysis based on nucleotide sequences of the intergenic region in the viral DNA-A provided evidence of two clusters of isolates: viruses isolated from species in the family Malvaceae, and viruses isolated from other dicotyledon families. Analysis of the capsid protein (CP) open reading frame grouped isolates into three geographical clusters, corresponding to isolates collected in Punjab, Sindh, or both provinces. Random amplified polymorphic DNA analyses of the B. tabaci population showed that intrapopulation diversity was high at both the local and regional scales. Sequence analysis of the mitocondrial cytochrome oxydase I (mt COI) gene showed that the B. tabaci population was structured into at least three genetic lineages corresponding to the previously described Indian, Southeast Asian, and Mediterranean-African clades. The Indian clade was present only in Punjab, the Mediterranean-African only in Sindh, and the Southeast Asian in both provinces. B. tabaci haplotypes of the Indian clade were found only in the Punjab, where CLCuD occurs. Hence, the geographical distribution of virus and vector genotypes may be correlated, because similar phylogenetic relationships were detected for the viral CP and the vector mt COI genes.

ABSTRACT Turtles are reptiles that live in the sea and are able to migrate over long distances along the Indian Ocean, Pacific Ocean and Southeast Asia. Currently the number of turtle populations in nature has greatly decreased. This population decline is caused by natural factors and human activities that endanger the population directly or indirectly. At this time the tagging set technique (ID tag code) is a method that is often used to detect the presence of turtles by attaching tags to female turtles who are landing to lay eggs on the beach or while in captivity or the discovery of the mother turtle by fishermen. One other method that can be used to detect the presence of turtles is to use the acoustic method. The purpose of this study was to analyze the characteristics of the acoustic backscattering energy of the green turtle (Chelonia mydes) and to analyze the relationship between target strength and total body length of the green turtle (Chelonia mydas). This research was conducted in the Tapak Paderi waters pond, Bengkulu City, in August-October 2020. The average target strength (TS) value for green turtles was -48.07 dB. Based on the regression equation, the value of determination (R2) obtained is 0.78. Where this value shows that the total length of the green turtle has an effect of 78% on the average target strength (TS) value, while for 22% it is caused by other factors such as body shape, environmental factors and other factors. Based on the ANOVA test, it can be concluded that there is a relationship between the total length and the value of the target strength (TS) on the green turtle or the value of the total length has an influence on the value of the target strength (TS) on the green turtle.
