“…kurstaki (Karuppaiah 2014), in terms of IPM, resulted in the efficient control of A. catalaunalis in sesame (Sasikumar and Kumar 2014). Furthermore, two applications of insecticides at 2 and 4 weeks after sesame germination resulted also in the efficient control of A. catalaunalis (Gebregergis et al 2016b). However, in Greece, to date, there is no chemical or microbial pesticide approved for the control of sesame crop pests.…”

In August 2016, severe infestations of sesame crops by the sesame leaf webber and capsule borer, Antigastra catalaunalis (Duponchel) (Lepidoptera: Crambidae), were recorded in rural areas of the Regional Unit of Drama, Northern Greece. Larval feeding-damage symptoms were observed on leaves and capsules. Infestations were recorded in all of the inspected sesame fields. The infestation levels were considerable high resulting in significant economic loss. To our knowledge, this is the first report of A. catalaunalis severe infestation on sesame in Greece.

“…Sesame is a crop that is adapted to deep soils which have a loamy texture, are well drained and good natural fertility. Regardless of having an optimal range of between 500 and 650 mm of water during its production phase (Grilo et al, 2013), sesame productivity is threatened by biotic and abiotic factors such as rainfall intensity and distribution on one side and insect pest on the other side; factors responsible for 0.35 -4 t/ha yield reduction in sesame production (Gebregergis et al, 2016). Therefore, productivity could be attained through creating new cultivars with high yield potentiality as well as application of suitable cultural practices such as fertilization, in-situ water harvesting technique and weed control etc (El-Habbasha et al, 2007).…”

Sesame (Sesamum indicum L.) is one of the exportable commodities in Ethiopia, though its productivity is threatened by moisture stress. This research aims to study effect of organic mulches and land preparation methods on sesame productivity and in-situ moisture conservation. The experiment was carried out in Humera, Western Tigray during 2015/16 growing season. The experimental design was factorial randomized complete block design with three replications. There were four type of organic mulches (rice straw, sorghum straw, sesame straw and "Sudan grass") compared with control (no mulching) and two land preparation methods (ridge and flat land preparation). Sesame, variety Setit-1 was used in the experiment. The organic mulching rate of application was 10 ton ha -1 and this was applied evenly to the soil immediately after emergence. Soil water content, phonological characteristics, yield and yield components of sesame were collected. Partial budget analysis was computed to evaluate the economic visibility of both factors. The data collected was analyzed with Genstat15 software and treatment showed that significant difference was subjected to mean comparison test. The analyzed results indicated that land preparation methods with organic mulching had significant effect on soil moisture content at different soil depth and grain yield. The highest yield (750 kg ha -1 ) was recorded under flat land preparation with "Sudan grass" while the lowest yield (140 kgha -1 ) was recorded under no mulch with flat land preparation methods. The economic analysis showed that flat land preparation with "Sudan grass" produces the highest net benefit (9,499 Birr) and marginal rate of return (223.3%). The overall result showed that investing 1.0 Birr on flat land preparation method mulched with "Sudan grass" earns 2.23 birr. Thus, using flat land preparation with "Sudan grass" as mulch could be an advantage to obtain highest yield and profit for the farmers in dry land areas.
