“…In Egypt, population densities of Sesamia cretica are high in the Nile delta, especially on early maize crops, sown between late March and mid-May (Mostafa, 1981), in which the borer may cause severe damage (Semeada, 1985 and1988). In another study, Ezzeldin et al (2006) revealed that the reduction of Sesamia cretica population play an important role in increasing the yield of maize and sorghum in Egypt where it attacks those crops less than 4 -6 week old. On the other hand, Adham et al (2009) showed that the cotton leafworm (Spodopetra littoralis) is a well polyphagous herbivore and is regarded as one of the most important agricultural pest in the Middle East.…”

The present investigation was carried out at Giza Agricultural Experiments and Research Station, Agricultural Research Center (ARC), Giza, Egypt during the two successive seasons 2016 and 2017. The objective of this investigation was to assess the effect of applied irrigation water, infestation with insects and infection with virus on cowpea and maize productivity, as well as farmer income under intercropping condition. The experiment included nine treatments which were the combinations between three applied irrigation water levels (80, 100 and 120% of the recommended applied irrigation water level of maize) and three cropping systems (intercropping cowpea with maize, sole cowpea and sole maize), in addition to recommended sole maize that grown on ridges 70 cm width and received 100% of applied irrigation water. The experimental design was a strip plot with three replications. Irrigation water treatments were randomly assigned to the vertical strips and cropping systems were allocated in the horizental strips. Data indicated that the highest applied irrigation water level (120% ETo) had higher water consumptive use than the others. The intercrops had higher water consumptive use than those of sole plantings. With respect to maize crop, increasing applied irrigation water from 80 to 120% ETo significantly increased infestation with aphids, jassids, Hawaiian beet webworm, cotton leafworm and whiteflies on maize leaves, as well as higher grain yield per ha and its attributes. Intercropped maize had higher infestation with aphids, jassids, cotton leafworm and whiteflies, as well as ear leaf area per plant than those of sole maize, meanwhile, the reverse was true for greater sugarcane borer. Intercropped maize plants that received the highest applied irrigation water (120% ETo) had higher infestation with aphids, jassids and cotton leaf worm on maize leaves than the other treatments, meanwhile higher ear leaf area per plant was recorded by application of the recommended applied irrigation water of maize (100% ETo). With respect to cowpea crop, increasing applied irrigation water from 80 to 120% ETo significantly increased infestation with aphids, jassids, leaf miner fly, Hawaiian beet webworm, cotton leafworm and whiteflies, as well as soybean mosaic virus (SMV) infection on cowpea leaves, beside higher plant height, number of branches per plant and forage yield per ha. Intercropped cowpea had lower infestation with aphids, jassids, leaf miner fly and Hawaiian beet webworm, as well as lower SMV infection and number of branches per plant and forage yield per ha than those of sole cowpea. Sole cowpea that received the recommended applied irrigation water of maize (100% ETo) had higher infestation with Hawaiian beet webworm, jassids and leaf miner fly on cowpea leaves than the other treatments, meanwhile, SMV infection was not by the interaction between applied irrigation water levels and cropping systems. Sole cowpea that received the highest applied irrigation water level (120% ETo) had a higher number of branches per ...

“…In a recent survey conducted in Tendaho sugarcane estate, northeastern Ethiopia, that started sugarcane production a few years before by clearing the natural vegetation, S. cretica was found as the only economically important sugarcane stem borer pest (Goftishu et al., ). Sesamia cretica is a major pest of sorghum and sugarcane in East and North Africa (Kfir et al., ; Leslie, ; Ezzeldin, Sallam, Helal, & Fouad, ). A similar survey carried out in three sugarcane estates located in the central Rift Valley of Ethiopia also found high infestation of S. nonagrioides and recorded the species for the first time as one of the major sugarcane stem borer pest in the estates (M. Goftishu, Y. Assefa, C. Fininsa, A. Niba, C. Nyamukondiwa, C. Capdevielle‐Dulac, & B. P. Le Ru, unpublished results).…”

Lepidopteran stem borers are among the most important insect pests of maize, sorghum and sugarcane in sub‐Saharan Africa. Except for Chilo partellus, the other stem borer pests in Ethiopia are indigenous to Africa and are assumed to have coevolved with some native grasses and sedges in the natural habitat. In addition to pest species, natural habitats harbour diverse non‐economic stem borer species, some of which are new to science. However, with the growing threats to natural habitats, some non‐economic stem borer species may switch or expand their host ranges to include cultivated crops and evolve as “new” pests. Besides host switch, some of the unknown species currently limited to natural habitats may disappear. We examined the diversity, abundance and interactions of lepidopteran stem borers and their wild host plants in five different vegetation mosaics in Ethiopia. The stem borer species diversity varied among vegetation mosaics and host plants. Forty‐four stem borer species belonging to 14 different genera in the families of Noctuidae, Crambidae, Pyralidae and Tortricidae were recorded from 34 wild host plants and through light trap. Among these families, Noctuidae was the highest in species richness in which 31 species were identified, out of which 15 species and two genera were new to science. This paper discusses the ecological interpretation of host plant–stem borer species interactions, particularly in relation to habitat disturbances.

“…Problems such as insect resistance and environmental contamination by insecticides (FAO 1998) soon developed, increasing both direct and indirect costs of insect control (Abate et al 2000). Much controversy now surrounds the whole subject of insecticide use (Ezzeldin et al 2008). In spite of recent emphasis on the development of alternative methods of insect control, the of bio-control agents to suppress the insect pests Gardner et al 2007;El-Wakeil et al 2008), the properly timed use of the right insecticide will, for the foreseeable future, continue to play an integral part in pest-management programs , and keep the environment clean (Bergweiler et al 2008).…”
