Methods: A total of 626 specimens were captured as a consequence of this investigation from 07 various places in the District of Mirpurkhas. Gryllidae are phytophagous insects that eat a vast number of crops, in addition, crickets damage paper, clothing, carpets and furniture. The standard entomological technique and instruments were used to correctly identify cricket species. The taxonomic work was mounted, labeled and sorted properly.
Result: As a consequence of this work during 2019-2020. 05 genera and 11 species with 01 subspecies belonging to 02 subfamilies of family Gryllidae were distinguished during the current examination. Out of these species, 01 species and 01 subspecies; Gryllus multipulsator and Gryllus (gryllus) assimilis assimilis subspecies were recorded for the first time from the area.
Ghouri and Ahmed (1959); Chopard (1969); Yunus et al., (1980); Ramzan (1984); Qayoom et al., (1987); Abdullah (1995); Saeed et al., (2000); Malik et al., (2015) and Riffat et al., (2016) all identified cricket fauna in Pakistan. The majority of researchers gathered material in Punjab, with only a few allusions to specific locations in Sindh in the literature, such as Karachi, Sukkur, Badin Hyderabad and the Thar Desert. As a result, the point of the study was to survey and identify cricket species in the district of Mirpurkhas-Sindh.
MATERIALS AND METHODS
The procedure proposed by Vickery and Kevan (1983) was used for specimen killing and preservation. All samples are obtained with an insect net and by hand. Captured samples were taken to the lab for additional examination. After killing all specimens in a glass jar with chloroform, samples were pinned using a standard entomological approach. The morphology and hidden genitalia of the obtained material were used to identify them. The Standard Entomological technique and instruments were used to correctly identify cricket species. The taxonomic work was mounted, labeled and sorted properly.
RESULTS AND DISCUSSION
Key to subfamilies of gryllidae occurring in district mirpurkhas
As a consequence of this work, 626 samples were collected from Digri, Jhuddo, Mirpurkhas, Mirwah (Shujaabad), Sindhri, Kot Ghulam Muhammad and Hussain Bux Mari in District Mirpurkhas (Table 1). The specimens were mostly captured from agricultural land, trees, herbs, natural vegetation and holes in homes, among other places. Gryllinae and Nemobiinae were the two sub-families that were identified from the collected material. These 02 subfamilies belong to 03 tribes (Gryllini, Medicogryllini and Pteronemobiini) and 05 genera (Acheta domesticus, Linnaeus, 1758, Acheta chudeaui, Chopard 1927, Acheta meridionalis, Uvarov, 1921, Acheta thoracica saeed et al. 2000, Gryllus bimaculatas, De Geer, 1773, Gryllus (gryllus) quadrimaculatus apicalis Bolivar, 1900, Teleogryllus (macroteleogryllus) mitratus Burmiester, 1838, Gryllus (Gryllus) assimilis assimilis Fabricius, 1775, subspecies, Gryllus multipulsator, Weissman, 2009, Grylline subfamily representatives Gryllodes sigillatus Walker, 1869 and Gryllodes supplicans Walker, 1859. Walker, 1871 identified Pteronemobius concolor as a member of the Nemobiinae family. Acheta domesticus ranked first with 30.51 per cent of the total species collected, followed by Gryllodes sigillatus with 23.32 per cent. Furthermore, a large number of specimens were taken in Digri (32.42%), followed by Mirwah (14.85%) and the smallest population of Gryllidae was found in Hussain Bux Mari (10.06%) and Sindhri (10.06%) (Fig 1).
The purpose of this study was to discover the cricket fauna and their host plants (Table 2) in the Mirpurkhas district. Several researchers have carried out taxonomic studies on the spread of the Gryllidae fauna. Chopard (1969) described species from Pakistan and neighboring countries that belong to 12 Grylliodea groups. Saeed et al., (2000) conducted a detailed survey of Gryllidae fauna in Pakistan, visiting various locations and identifying fauna at the family, subfamily and generic levels. However, the number of workers collected material from Punjab and only references to specific areas in Sindh, such as Karachi, Sukkur, Badin, Hyderabad and the Thar Desert, can be found in the literature.
