Effects of two plant extracts on the damage of Meloidogyne incognita in tomato plants [İki bitki ekstrakti{dotless}ni{dotless}n domates bitkilerinde Meloidogyne incognita, chitwood (Nematoda: Heteroderidae) zarari{dotless}na etkileri]

The effects of the aqueous extracts of Euphorbia myrsinites (Euphorbiaceae) and Urginea maritima (Liliaceae) on the damage of Meloidogyne incognita (Nematoda: Heteroderidae) to tomato plants was evaluated. The trials were conducted in two series in climatized rooms and in greenhouse conditions. The results of both the climatized rooms and greenhouse trials are parallel each other. All dilutions (1:100, 2:100 and 4:100 v v-1) of the extracts applied to the soil reduced the root galling caused by M. incognita and enhanced tomato yield compared to an untreated control. Efficacy of the highest concentration (4:100 v v-1) of both extracts on the control of M. incognita was similar to the positive chemical control (Oxamyl). The highest concentration of U. maritima was superior to the extracts of E. myrsinites. Aqueous extracts from these two plants reduced the damage of root-knot nematodes

Review of the Turkish Dolichopodidae (Diptera) with first description of male Hercostomus phoebus Parent, 1927, new synonyms and new records

Male Hercostomus phoebus Parent, 1927 hitherto known only from female is described for the first time. Two new synonyms are proposed: Dolichopus thalhammeri Knézy, 1929 (=Dolichopus balius Meuffels, 1982, syn. n.); Tachytrechus beckeri Lichtwardt, 1917 (=Tachytrechus gussakovskii Stackelberg, 1941, syn. n.). New records for 48 dolichopodid species collected in Turkey are given. The fauna of the region comprises now 69 specie

The invasive Liriomyza huidobrensis (Diptera: Agromyzidae): understanding its pest status and management globally.

Liriomyza huidobrensis (Blanchard) is native to South America but has expanded its range and invaded many regions of the world, primarily on flowers and to a lesser extent on horticultural product shipments. As a result of initial invasion into an area, damage caused is usually significant but not necessarily sustained. Currently, it is an economic pest in selected native and invaded regions of the world. Adults cause damage by puncturing abaxial and adaxial leaf surfaces for feeding and egg laying sites. Larvae mine the leaf parenchyma tissues which can lead to leaves drying and wilting. We have recorded 365 host plant species from 49 families and more than 106 parasitoid species. In a subset of the Argentinian data, we found that parasitoid community composition attacking L. huidobrensis differs significantly in cultivated and uncultivated plants. No such effect was found at the world level, probably due to differences in collection methods in the different references. We review the existing knowledge as a means of setting the context for new and unpublished data. The main objective is to provide an update of widely dispersed and until now unpublished data, evaluate dispersion of the leafminer and management strategies in different regions of the world, and highlight the need to consider the possible effects of climate change on further regional invasions or expansions
