The seasonal abundance of spider mite T. urticae on twenty vegetable and twenty four ornamental plants in Rajshahi was conducted during August 2010 to January 2011. The mite was present on joscpks coat, kathua, lady’s finger, cucumber, brinjal, tomato, bottle gourd, bean, loofah, spinach, bitter melon, pointed gourd, radish, and cowpea but no mite was recorded on other six plants. But all the ornamental plants bagan-bilash, bottlebrush, nayantara, morog-jhuti, hasnahena, chandramallika, dalia, krisno-chura, togor, joba, madhobilata, rongon, beli, daisy, sondhamaloti, kamini, musanda, rakto-karobi, shewli, kath-golap, rajanigandha, golap, ganda, zinia contained mites. The pick population was prevailed during August. The increase of mite number is directly related with the increase of temperature. DOI: http://dx.doi.org/10.3329/ujzru.v30i0.10745 Univ. j. zool.

A survey of the Odonate fauna was conducted in the Sylhet and Srimangal Districts of Sylhet Division and Chittagong, Khagrachari, Rangamati, Bandarban and Cox’s Bazar Districts of Chittagong Division. The designated areas were visited periodically for nearly seven years from 1994 to 2000. The present paper includes a list of the odonate species collected during the survey period. A total of 764 specimens were collected which comprised 49 species of Anisoptera in 32 genera, and 47 species of Zygoptera in 18 genera. Of these 15 species in 8 genera of the former and 27 species in 11 genera in the latter suborder are new records from Bangladesh. The collection also includes females of three species and males of two species that happen to be new to science. The specimens are preserved in our personal collection.

Field studies of butterflies were carried out in four different selected areas i.e. Krishnopur, AERE campus, Rajalak Farm and Horters (Part of JU campus) at Savar, Dhaka. Butterflies identified of those areas constituted 158 species belonging 10 families, 87 species of which are newly-recorded in Bangladesh. Numbers of species identified in each family reached 47 in Lycaenidae (30 newly recorded), 32 in Hesperiidae (22 new), 22 in Pieridae (11 new), 19 in Nymphalidae (6 new), 14 in Papilionidae (7 new), 14 in Saytridae (8 new), 5 in Danaidae (1 new), 3 in Riodinidae (1 new), 1 in Acraeidae and 1 newly recorded Amathusiidae. The maximum 130 species and the minimum 65 species were recorded in Krishnopur and Rajalak Farm, respectively. Almost all butterfly families were found to be dominant in Krishnopur. Among the total identified species, 35.44% belonged to very rare (VR) and 20.25% to rare (R) categories, whereas 12.18%, 12.03% and 13.29% species were very common (VC), common (C) and not rare (NR) categories, respectively. It may be that the numbers of butterfly species as well as their fauna vary greatly depending on the floral and ecological conditions in and around the study areas.

Some aspects of the reproductive biology viz. sex-ratio gonadal length index (G.L.I.), gonado somatic index (G.S.I.) and sex-ratio of Cirrhina reba were studied during September 2004 to July 2005. In present study the highest values of GLI (33.76) and GSI (0.63) were in the month of July. Total length (TL) and gonadal length (GL), total weight (TW) and gonadal weight ( GW ), standard length (SL) and gonadal length ( GL ) and gonadal weight relationships were found to be positive; and the relationships were: GL = -3.873 + 0.219 TL (r = 0.992), GW = 0.01511+0.000815 TL (r = 0.979), GL = -2.6030+0.253 SL (r = 0.990), GL = 0.01997+0.000938 SL (r= 0.976), GW = 13.2952+0.6064 TW (r = 0.958), GW = 0.0772+0.00233 TW (r = 0.979). The sex- ratio of C. reba were 1:1.62 for male and female respectively. The Chi-square test showed significant differences of sex-ratio among months and totals.

The study was conducted to investigate the incidence of gastrointestinal parasites of buffalo in different slaughter houses of Chittagong Metropolitan Area, Bangladesh. A total of 100 faecal samples were collected from three slaughter houses and studied by coproscopic examinations. Direct smear, sedimentation and floatation techniques along with egg micrometry were conducted to identify various parasitic eggs. Among 100 faecal samples 69% were positive for different individual parasitic infestation. Trematodes, nematodes, cestodes and protozoan infestations were 48%, 16%, 2% and 3%, respectively. Among the trematodes Schistosoma sp. (23%), Paramphistomum sp. (15%) and Fasciola sp. (10%) were found. Incidence of nematode infestations were Toxocara sp ( 4%) , Oesophagostomum sp . (5%), Cooperia sp . (2%) , Bunostomum sp. (3%) and 1% for both Trihostrongylus sp. and Strongyloides sp. Mixed infection were observed 7% of positive samples. Results indicate that the heavy worm burden in buffaloes causes severe economic loss to the farmers by reducing the overall productivity.

A study was carried out in Faridpur, Habiganj and Barisal to identify the prevalence of diseases, morbidity and mortality of Black Bengal goats (BBGs) under semi-intensive system reared by moderate and ultra poor households in Bangladesh during the period from February 2008 to July 2009. A total of 168 female goats and 9 bucks were recorded from two types of households of which 125 goats were infected (74.70%) by a number of diseases and lead to mortality (17.26%). Survival rates and mortality percentage of kids were 80.60 and 19.40, respectively but the highest mortality was in Habiganj (21.18%). Seasons had special influences on mortality of adult goats (35.81%) and kids (64.19%) where the highest mortality rates were 22.22% and 25.93%, respectively in rainy season. PPR had the highest mortality rates (37.93% in adults and 25.00% in kids) followed by pneumonia (24.14% and 21.15%, respectively). Predator invasion was the other remarkable cause for increased kids’ mortality (23.08%).

在2008年2月至2009年7月期间，在Faridpur、Habiganj和Barisal开展了一项研究，以确定孟加拉国中等和极端贫困家庭在半集约化系统下饲养的黑孟加拉山羊(bbg)的患病率、发病率和死亡率。共记录了来自两类家庭的168只母山羊和9只公山羊，其中125只山羊感染了多种疾病(74.70%)并导致死亡(17.26%)。儿童生存率和死亡率分别为80.60%和19.40%，但死亡率最高的是哈比干季(21.18%)。季节对成年山羊(35.81%)和幼山羊(64.19%)的死亡率有特殊影响，其中雨季死亡率最高，分别为22.22%和25.93%。小反刍兽疫死亡率最高(成人37.93%，儿童25.00%)，其次是肺炎(分别为24.14%和21.15%)。食肉动物入侵是儿童死亡率增加的另一个显著原因(23.08%)。该研究表明，在农村一级的羊羊半集约化饲养系统中，卫生管理实践、充足的营养供应以及疫苗接种和驱虫规划将提高成年山羊和山羊的存活率。DOI: http://dx.doi.org/ 10.3329/ujzru.v30i0.10702 Univ. j. zool。Rajshahi university .

A total of 168 female goats and 9 bucks were recorded from two types of households of which 125 goats were infected (74.70%) by a number of diseases and lead to mortality (17.26%). Survival rates and mortality percentage of kids were 80.60 and 19.40, respectively but the highest mortality was in Habiganj (21.18%). Seasons had special influences on mortality of adult goats (35.81%) and kids (64.19%) where the highest mortality rates were 22.22% and 25.93%, respectively in rainy season. PPR had the highest mortality rates (37.93% in adults and 25.00% in kids) followed by pneumonia (24.14% and 21.15%, respectively). Predator invasion was the other remarkable cause for increased kids’ mortality (23.08%).

Dishwashing liquids viz . Vim and Trix at concentrations of 0.5, 1.0, 1.5 and 2.0% were toxic against the adult American cockroach, Periplaneta americana L. after 24-h of exposure. Knockdown effect of the detergents was found to be 70-78% by contact with both the detergents. Whereas, by dipping 100% of the cockroaches were knocked down and ultimately died at 24-h exposure. The LC 50 values were calculated for contact toxicity were 1.490% for Vim and 0.883% for Trix. The results revealed that Trix is more toxic than Vim against the adult P. americana.

The research work was conducted to find out the seasonal occurrence of parasites of the major carp, Cirrhina mrigala from different water bodies of Rajshahi district during April 2009 to January 2010. A total of 95 fishes were examined of which 72 fishes were infected. Thirteen species of parasites viz. Trichodina pediculatus, Chilodonella cyprini, Ichthyophthirius multifiliis, Apiosoma sp., Dactylogyrus vastator, Gyrodactylus elegans, Hirudo sp., Argulus foliaceus, Lernaea sp. Phyllodistomum agnotum, Eucreadium sp., Camallanus ophiocephali and Pallisentis sp. were recorded from the infected fishes. Among all the parasites G. elegans was the most dominant parasite and skin had been found as the most vulnerable site for parasitic infestation. The maximum infestation was observed in winter season and the minimum infestation was observed in rainy season. Key words: Cirrhina mrigala; parasite; prevalence; abundance; mean intensity; infestation. DOI: http://dx.doi.org/10.3329/ujzru.v29i1.9465 UJZRU 2010; 29(1): 47-50
