“…In this study, reductions in grain yield of wheat varieties varied between 4.3% and 25.7% over the 2 growing seasons. In other studies, yield losses in wheat caused by H. avenae were reported to be between 15% and 20% in Pakistan (Maqbool, 1988), 40% and 90% in Saudi Arabia (Ibrahim et al, 1999), and 23% and 50% in Australia (Nicol et al, 2002). Thus, our work demonstrates that the damage from H. avenae is lower in Turkey than in the other countries mentioned above.…”

Cereal cyst nematode Heterodera avenae is found predominantly in the spring wheat-growing areas in Adana Province in the eastern Mediterranean region of Turkey. The impact of H. avenae on wheat yield has been observed but not quantified. This study was conducted to determine the effect of H. avenae on the yield of 6 wheat varieties in the 2011/2012 and 2012/2013 growing seasons in the naturally infested fields of Adana. According to our results, H. avenae significantly suppressed grain yield of the wheat varieties, ranging from 4.3% to 25.7%. Negative or positive linear regressions between the reproduction factor of H. avenae and grain yield of the wheat cultivars depended on the variety. Regression analysis of the data revealed that reproduction factors of H. avenae were positively correlated with grain yield in cultivars Adana-99, Ceyhan-99, and Silverstar, whereas reproduction factors were negatively correlated with the Karatopak, Osmaniyem, and Seri-82 cultivars.

“…initial nematode inoculum density has been reported in several crops by early authors (Di Vito et al, 1986Vito et al, , 2004Vovlas et al, 2008;Sharma and Sharma, 2015 (Lamondia and Brodie, 1986;Rioval and Sarr, 1987;Ibrahim et al, 1999). The decrease in the reproductive factor with an increase in the inoculums density could be attributed to increased competition for feeding sites among the nematodes and the greater damage of infected roots with increasing initial population (Al-Abed et al, 2013).…”

Root-knot nematodes cause substantial economic yield loss in tobacco production and many other crops in the world. Their control has been achieved for decades by use of chemical nematicides. However, concern for the environment has led to the banning and phasing out of some effective chemical nematicides. The use of crop rotation is one of the environmentally friendly and sustainable management strategies for managing root-knot nematodes, insect pests and pathogens. The strategy is widely used by resource poor farmers in developing countries. In this study, greenhouse experiments were conducted with the objective of evaluating four leguminous crops (groundnut, sunhemp, common bean and cowpea cultivars) for their efficacy in the management of the root-knot nematode (Meloidogyne javanica). Experimental plants were grown in 15 cm diameter pots and artificially inoculated with nematode eggs. Four different initial inoculums levels of 0, 500, 1,000 and 1,500 nematodes eggs per plant were used. After inoculation the plants were maintained in the greenhouse for 54 days. Thereafter, the nematode reproductive factor and the number of eggs were evaluated. Significant differences (P<0.05) in nematode population built up were observed in plots with the different legumes. Generally, all the groundnut cultivars were effective in reducing populations while common bean was a susceptible host and supported high nematode populations. The results from this study demonstrate that some leguminous crops affect this pest's capacity to develop within their roots. The test legumes may contain compounds that either kill or deter root-knot nematode reproduction.

“…Significant economic losses have been reported from different continents (Nicol & Rivoal 2008, Sahin et al 2009). In China, studies conducted in the provinces Anhui, Henan and Hebei indicated yield losses in wheat of 10-40% (Peng et al 2007), whereas in Saudi Arabia losses range from 40 to 92% in wheat and from 17 to 77% in barley (Ibrahim et al 1999). Studies in Oregon (USA) have indicated losses in spring wheat of 35% (Smiley et al 2005).…”

Distribution of the Cereal Cyst Nematodes (Heterodera spp.) in Wheat and Barley Fields in North-Eastern Regions of Syria

et al. 2015

Cereal cyst nematodes (CCN) are important plant-parasitic nematodes of wheat and barley, and exist in most of the cereal growing regions of the world. As there is limited information on the nature and distribution of CCN species in Syria, a survey was conducted in north-eastern Syria to assess the distribution of CCN in the main wheat and barley growing areas. In the summer of 2009, a total of 167 composite soil samples were collected from 167 wheat and barley fields. Cysts were extracted from soil using the Fenwick can technique, then quantified and identified up to the species level by using both morphological and molecular methods. The study revealed that 62% of the fields were infested with the three Heterodera species: H. avenae, H. filipjevi and H. latipons. However, the most prevalent species was H. latipons, which was present in 76% of the infested samples, while it occurred alone in 67% of those samples. Heterodera avenae was detected singly in 20% of the samples, while 11% consisted of mixed populations with other species. Heterodera filipjevi was never detected alone; it was found mixed with H. avenae and/or H. latipons in 9% of the samples. The high number of extracted cysts (up to 116 cysts × 200 g -1 of soil) is most likely related to the monoculture practiced in that region and the fact that growers are unaware of the existence of resistant varieties.
