Key to the Tribes and Genera of Deltocephaline Leafhoppers (Auchenorrhyncha, Hemiptera, Cicadellidae) of Pakistan

Abstract A key with accompanying figures is provided for the 14 tribes and 35 genera of Deltocephalinae (Cicadellidae) from Pakistan.

Systematic status of true katydids Sathrophyllia (Orthoptera, Tettigonioidea, Pseudophyllinae) from Pakistan, with description of two new species.

Abstract The genus Sathrophyllia Stål, 1874 from Pakistan is reviewed with four species recorded. The diagnostic characters are given and two new species Sathrophyllia saeedi sp. n. and Sathrophyllia irshadi sp. n. are described. In addition to that Sathrophyllia nr. rugosa (Linnaeus, 1758) and Sathrophyllia femorata (Fabricius, 1787) are re-described. Further information on the distribution and ecology of the species is given and a key to studied species of Sathrophyllia is presented. Sathrophyllia femorata (Fabricius, 1787) and Sathrophyllia rugosa (Linnaeus, 1758) are recorded from Rawalakot (KPK) and Tharparker (Sindh), Pakistan for first the time.

Fiber Quality Evaluation of Pakistan’s Locally Developed Cotton Varieties for Yarn Manufacturing

ABSTRACT This paper discusses relation between fiber quality parameters and yarn quality, presenting results of the quality assessment of Pakistan’s five popular cotton varieties. Abadgar-901 was found to have highest effective length followed by Tarzen-1 when compared to other fibers studied and the Sattari showed the least effective length. Whereas, Tarzen-1 showed highest tenacity, Sindh-1 was second to that, yet Nayab-78 showed the least strength of the studied cotton fibers. Further, it was also found that except Nayab-78, all the other cotton varieties were found to have fineness value of premium cotton standards, however, Nayab proved to be a coarse fiber, Sindh-1 was finest fiber of them all. Moreover, Sattari was found to be the whitest in color when measured for CIE and Berger whiteness index, Nayab-78 followed it just after and the Abadgar proved to be the least white compared to the studied cotton varieties.

Identification and Oviposition Response of Sitophilus oryzae (L.) (Coleoptera: Curculionidae: Dryophthorinae) on Various Food Grains

In this study weevils were collected from the local areas of Tandojam and its surroundings. While further identification was performed at the Laboratory of postgraduate student, Department of Entomology, Faculty of Crop Protection, Sindh Agriculture University, Tandojam. The collected weevils from the local areas of Tandojam, were killed in a jar by applying potassium cyanide and were mounted through entomological pins on their right elytron. The specimens were also labeled, which contains information about the date of collection, name of collector, host of plant if was known. After that abdomen were separated and put at 10% potassium hydroxide for overnight at room temperature separately and were heavily sclerotized. The specimens were also heated for 10 minutes. In the next day these specimen were rushed in water for 5 minutes. During this experiment habitus images were taken with the help of camera fitted in microscope. The examination of gentile and other remaining parts were performed under the microscope for capturing of necessary images. For habitus images model of camera canon Power shot (sx510 HS) were utilized and for the gentile organ images USB camera fitted microscope 350k pixel (1) Kyowa Medilux (2) Labomed CSM2 20 to 40x were used. For the oviposition response on various grains, tested grains include; wheat, barley, oat, maize, gram, millet. A pair of newly emerged Sitophilus oryzae (Fabricius, 1775) from a laboratory colony was placed in plastic jars of 150 ml. There were 6 treatments, each treatment with 3 replications. Eggs were counted in each jar containing pair of weevils. Analysis was carried out through statistical software SXW 8.0, to categorize the preference of Sitophilus oryzae .

Genus Exitianus (Auchenorrhyncha, Cicadellidae, Deltocephalinae, and Chiasmini) in Tando Jam, Sindh, Pakistan

Abstract Exitianus Ball, 1929 is studied from Tando Jam, Pakistan. Two species, Exitianus indicus (Distant, 1908) and Exitianus nanus (Distant, 1908), are reviewed and their characters, habitus, and line drawing are given.
