“…A gall usually forms 1-2 days after juvenile penetration, with gall size correlated with the number of nematodes present in the tissue (Eisenback and Triantaphyllou 1991). The presence of nematodes in plant root tissues is difficult to see directly, specifically for female nematodes, as they are in root tissue and have a color similar to that of plant root tissue (Mutalaliah et al 2019). Therefore, the presence of rootknot nematodes in plant tissues can be observed through staining by the Bybd method.…”

Abstract. Plena SNG, Indarti S, Widiastuti A, Putra NS. 2022. Identification of the root-knot nematode species associated with Carica papaya.Biodiversitas 23: 6212-6217. Root-knot nematodes (Meloidogyne spp.) are important economic pests causing low production and yield losses in horticultural crops. Meloidogyne spp. is widespread and regarded as a major pest since they are found all over the world in a variety of geographic locations, most frequently found in tropical and subtropical climate zones. They are obligate parasites that feed on various plants, including papaya and other horticultural plants. They are root-galling in host plants. Many species of root-knot nematodes may be found in a suitable environment. Therefore, accurate identification of the root-knot nematode species in papaya plants is important for developing and applying control and management measures. Surveys and sampling of nematodes on papaya plants were performed at the Agrotechnology Innovation Center, Universitas Gadjah Mada, the Special Region of Yogyakarta, Indonesia, and its surroundings. Identification was performed both morphologically (based on the perineal pattern of female nematodes) and molecularly (using root-knot nematode species-specific primers). The results revealed that the species of root-knot nematode associated with papaya plants was Meloidogyne javanica based on the perineal pattern of female nematodes, specifically the lateral lines. This finding was also supported by the results of the DNA amplification at 670-bp product using specific primers for M. javanica (FJav/RJav). Consequently, plant protection efforts will need to focus on minimizing M. javanica damage in papaya cultivation.

“…Male nematodes will migrate from the roots whereas females remain sedentary and continue to feed on giant cells (Eisenback and Triantaphyllou, 1991). The egg sacs are typically attached to the posterior of the females and are slightly darker brown color than the gall tissue (Mutalaliah et al 2019).…”

“…Root-knot nematodes (RKNs) are the most problematic and destructive in warm moist sandy soil conditions. Under these conditions, they highly caused a reduction in the yield, quality, and quantity of the sweet potato tubers [10][11][12]. e well-known RKN species are Meloidogyne incognita [9,12] and M. enterolobii (guava root-knot nematode) [12].…”

Sweet potato is the seventh-ranked food crop produced after wheat, rice, maize, potato, barley, and cassava in the world. It is the most important root tuber crop in temperate, subtropical, and tropical areas of the world. It is grown for food, income-generating, and jobs for farmers and retailers. The important nutritional substances of sweet potatoes are ß-carotene and anthocyanins. However, the production and its valuable products are limited due to root-knot nematode parasitism. One of the most important destructive species of root-knot nematode to this crop is Meloidogyne incognita. The most destructive stage to sweet potato is at its second juvenile stage (J2). At this stage, it invades the roots and tubers of sweet potato highly in warm sandy soil conditions. It is an obligate plant-parasitic nematode. M. incognita caused significant yield loss to sweet potato in terms of quality, quantity, disturbing the process of photosynthesis and nutrient uptake through the formation of galling, establishing of its feeding sites, or induced galls that contain giant-feeding cells, and cracking of tubers and roots directly. It also reduces the market values of the infected tuber of sweet potato by downgrading the production values. The problem of quality and quantity losses to sweet potato by this pest is one of the major problems nowadays. It caused this problem alone or interaction with other plant-parasitic pathogens or through synergistic of fungi, bacteria, viruses, and others. Therefore, this review paper is focused on the sweet potato M. incognita biology, taxonomy, geographical distribution, and management measures.

Abstract. Putri A H, Indarti S, Harjaka T. 2021. Diversity and abundance of nematodes in soil treated with solarization treatments. Biodiversitas 22: 2612-2618. Solarization is a tillage cultivation technique that influences the presence of nematodes in agricultural land. This research aims to determine the solarization effect on soil temperature and nematode abundance and diversity in the soil. Observations on species, diversity, and abundance of the nematodes were performed at the Nematology Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, Gadjah Mada University. A completely randomized design (CRD) was used with six treatments and three replications. Meanwhile, the treatment groups were based on solarization duration (in days) on the soil which includes A(3), B(7), C(14) D (30), and K0 (control, without solarization) and K1 ( control, farmer treatment). Field observations were performed to measure soil temperature, moisture, and pH. Nematodes were analyzed in the laboratory to determine the genus, abundance, and diversity. Furthermore, extracted plant-parasitic nematodes were isolated by using the whitehead tray method while the entomopathogenic group was isolated using the baiting method. The results showed the differences in tillage treatment and solarization affect soil temperature (diversity and abundance). A polynomial regression model explained the relationship between increased solarization time and soil temperature. The highest soil temperature was found in cultivated land and solarization land for 14 days (41.0oC) and the lowest was in the treatment of farmers (33.67oC). The lowest abundance was found at 14 days solarization, namely 286 individuals/100g, and the diversity index value of 1.37. The highest diversity index was found in the treatment of farmers with an index value of 1.75. The solarization treatment is best applied in the field for 14 days.
