Diversity of beetles associated with watermelon crops Citrullus lanatus (Thunb.) Mats. in the region of Ouargla (southern Algeria)Acrónimo: MCNB-Kacha-et-al-2021
We studied the diversity of beetle families in watermelon fields in the palm grove of Zaatote at Ouargla (34° 54' N., 5° 20' E.). The sampling method used was Barber pots as they allowed the largest number of captures of insects, regarding both individuals and species. Over the three years of the study (2016, 2017 and 2018), we identified 787 individuals from 12 taxonomic families. Throughout the sampling period, the Coccinellidae family was clearly dominant, with an Fc% of 35.02 % in 2016, 36.2 % in 2017 and 34.34% in 2018. The second most dominant family was Tenebrionidae with an Fc% of 26.35% in 2016, 30.04% in 2017, and 33.33% in 2018. Other families were poorly represented. In 2016, regarding their trophism, 18 species of beetles (30.91%) were phytophagous and feed on the watermelon crop, while 26 species were predatory and decomposing auxiliaries.
The present experiment was carried out in the palm grove of Zaatote at Ouargla. This palm grove is located on the road between the region of Ouargla and El-Goléa (10 km south-east of Ouargla). The region of Ouargla is located in the Saharan bioclimatic zone. It has clay-sandy soils. The winter is temperate and summers are hot and dry.
Calidad de los datos
Insects were identified by Professor Faiza Marniche at the zoology laboratory at the National Veterinary School of El Alia, and confirmed in the Arthropod section of the Museu de Ciències Naturals de Barcelona by Mr. Amador Viñolas.
The identified species were classified according to the trophism of images and grouped into four functional groups: pests, predators, scavengers and miscellaneous in order to determine the role played by each species.
Recorded data based on identified beetle catches were analysed using software PASTsoftware (PA-leontologicalSTatistics) Version 2.17 (Hammer et al., 2001). The following numerical indices were used: the centesimal frequency (Fc), the Shannon Diversity Index (H’)and the Pielou equity index (E).
