“…Contrastingly, Mutlu et al (2016) observed that weeds increased the population of cicadellids in rice fields as 71.4% of individuals were recorded from weedy fields, whereas 28.6% were noted from weed-free fields. On the other hand, Paradell et al (2014) reported that weeds resulted in significantly higher leafhopper species from rice fields. Similar studies in different crops have reported that certain weeds (such as Johnson grass, purslane, nutgrass and common cocklebur) significantly increase the population of Cicadellidae, indicating the necessity of weed control (Andow, 1992;Margues et al, 2012;Mutlu and Sertkaya, 2015a).…”

Weed-insect interaction has been studied for decades to determine the role of weeds in insect infestation. This study investigated the impact of weed density on the population density of important leafhopper species (Cicadellidae: Hemiptera) and their egg parasitoid Anagrus atomus (L.) (Hymenoptera: Chalcidoidea) in maize (Zea mays L.) planted as second crop in Şanlıurfa province, Türkiye during 2022 and 2023. Population densities of harmful leafhopper species, i.e., Zyginidia sohrab (Zachvatkin), Empoasca decipiens (Paoli), Asymmetrasca decedens (Paoli), Psammotettix striatus (Linnaeus), and their parasitoid, i.e. A. atomus were monitored by yellow sticky traps (RAL-1016) under weedy and weed-free conditions. Three traps were hung in each experimental unit and the densities of target species were recorded weekly. The population densities of leafhopper species feeding on Sorghum halepense (L.) (Johnsongrass) and the effect of A. atomus on their population density were also determined in weedy treatment. A total 15 maize leaves were taken from both weedy and weed-free treatments, and S. halepense leaf tissues containing leafhopper eggs parasitized by A. atomus were counted weekly. Weed density had non-significant effect on the population density of Z. sohrab during both years. Contrastingly, increasing weed density increased the population density of E. decipiens & A. decedens complex in 2022. Nevertheless, weed density had non-significant effect on the population density of E. decipiens & A. decedens complex during 2023. Weedy treatment recorded higher population density of P. striatus (140 and 100 adults, respectively); however, both weedy and weed-free treatments recorded similar density (125 and 97 adults) during 2023. Weed density proved a significant factor in increasing A. atomus density. A total of 2935 parasitized eggs were recorded from the weedy treatment, whereas 1609 parasitized eggs were recorded from weed-free treatment. Although direct relationship between leafhoppers and weed density remains uncertain, integrated pest management strategies must consider phytophagous insects feeding on weeds at field edges and within fields and the natural enemy complex.

“…Diğer iki familyadaki birey sayıları yabancıotlu-otsuz karakterde sayısal olarak yakın değerler elde edilmiş ve yabancıotların bu iki familyanın popülasyon yoğunluğu üzerinde önemli bir etkisinin olmadığı sonucuna varılmıştır. Cicadellidae familyası için elde edilen sonucu destekler nitelikte, Paradell et al (2014), çeltikte yabancıotlar üzerinde %83, yabancıotsuz alanda ise %17 oranında yaprakpiresi belirlediklerini ve yabancıotlu alanların çeltikten daha fazla yaprakpiresi toplandığını bildirmişlerdir. Yabancıotlu ve otsuz alanlardan elde edilen verilere yapılan varyans analizi Çizelge 2 ve 3'te verilmiştir.…”

The species of Cicadellidae, Cixiidae and Delphacidae (Hemiptera) on Karacadag rice and the effects of weeds on their populations were investigated in Diyarbakir and Sanliurfa provinces between 2010-2012. For specimen collection, sweep net and D.vac were used, and randomized complete block desing were employed by hanging yellow sticky traps for monitoring the populations of fluctations and densities of Cicadellidae and Delphacidae family in weedy and unweeded plots. A total of 17 species including 10 species belonging to Cicadellidae family, 3 species Ciixiidae and 4 species from Delphacidae were determined. The most abundant and common species were recorded to be Agallia harrarensis Melichar, 1911 and Empoasca sp., from Cicadellidae, Tachycixius desertorum (Fieber, 1876) and Hyalesthes obsoletus Signoret 1865 from Cixiidae, Laodelphax striatellus (Fallen), Sogotella vibix from Delphacidae family. It was determined that the weeds in rice increased the population of cicadellid and while 71.4% of individuals was captured from weedy plots, 28.6% was obtained from unweeded plots. The population of Delphacidae and Cixiidae were recorded slightly higher in weedy plots The population densities of Cicadellidae and Delphacidae began to increase starting from vegetative stage and reached to pick level at generative-maturity stage. It is suggested that the control of weeds must be performed strictly and to be considered in rice cultivated areas.

Genus Plesiommata Provancher (Hemiptera: Cicadellidae) in Argentina: first detailed description of the female genitalia and comparisons with its neotropical congeners

2016

Plesiommata Provancher is a sharpshooter genus with six species described, three present in the Neotropics. The morphology of the female genitalia of this genus is still poorly known. In this contribution, the female genitalia of P. mollicella (Fowler) and P. corniculata Young are described and illustrated for the first time. The vector species P. corniculata Young is recorded as new for Argentina. A key to Neotropical species including new female genital characters is presented along with updated information as new distribution records, host plant records and phytosanitary importance.
