“…In recent years, pest control of stored products (including T. granarium ) is undergoing a rapid change from an insecticide-based approach to an integrated management. Host plant resistance is an alternative approach for pest management, as it is both economically and environmentally acceptable (Golizadeh & Razmjou, 2010). Evaluating the resistance of various cultivars and crop species to pests may offer useful information about their suitability or unsuitability for the target pest species (Tsai & Wang, 2001; Golizadeh et al ., 2016).…”

The Khapra beetle, Trogoderma granarium Everts (Coleoptera: Dermestidae), is a common pest of cereal grains and other stored products. In this study, the effects of ten barley cultivars (Abidar, Bahman, Line20, Line22, Line30, Lisuei, Lokht11, Makuyi, Sahand, and Sahraa) were evaluated on life table parameters and nutritional indices of T. granarium under the following laboratory conditions: 33 ± 1°C, 60 ± 5% RH, and a photoperiod of 14: 10 (L: D) h. Life history parameters of T. granarium could be appropriate indices in resistance and susceptibility evaluation of barley cultivars. The maximum survival rate of immature stages was observed on Makuyi and Lisuei cultivars and the minimum rate was on Abidar and Line22 cultivars. The shortest development time was on Makuyi cultivar and the longest on Line22 cultivar. Pupal weight was ranged from 2.56 mg on Lokht11 to 4.86 mg on Makuyi. Fecundity and egg-hatching rates were highest on Lisuei cultivar and the adults were long-lived on Makuyi cultivar. The highest r m values were observed on Makuyi and Lisuei cultivars but lower value of it resulted from rearing of T. granarium on Line22 cultivar (0.0350 female per female day-1). The results showed that T. granarium larvae fed on Makuyi cultivar had higher values of relative consumption rate and relative growth rate. The results indicated that Makuyi and Lisuei cultivars were relatively susceptible barley cultivars and Line22 was the most inappropriate cultivar for feeding of T. granarium, which could prove useful in the development of Integrated Pest Management programs for this pest.

“…In field experiments, glandular trichome clones showed a high level of resistance to potato pests, including PTM [69]. The cultivation of resistant varieties could reduce the chemical application and increases the effectiveness of alternative control methods [70]. It is known that some varieties such as earliness and deep tuberization that are set deeper in the hills have less potential for tuber infestation.…”

Potato is the fourth major crop of the world after rice, wheat and maize. However, in Ethiopia, the yield per unit area of potato is very low compared to those of other countries. There are many factors that reduce the yield of the crop among which the diseases like late blight and insect like tuber moth which play an important role in reduction of the yield. Hence, the objective of this review is to review the importance of these late blight and tuber moth of potato and their management in Ethiopia. In Ethiopia, late blight is occurs throughout the major potato production areas and researches have made estimates of losses ranging from 6.5 to 61.7%, depending on level of susceptibility of the varieties. Different types of management options like cultural, Fungicide Use, biological and Resistant Cultivars are the major management practices which can help in reducing late blight effect. However, because of its new strain development, there is no single effective management strategy of this disease. Therefore adopting integrated disease management approach is the most effective, environmentally safe and low costly to the users. In addition to late blight, potato tuber moth can also cause significant yield loss to potato. Potato tuber moth is the most important constraints of potato production in Ethiopia and it causes up to 42% yield loss in storage. Using different integrated pest management approaches including appropriate cultural practices, using pheromone traps, using biological control, host plant resistant, using botanicals and appropriate rate and time of chemical applications are used for reducing the damage of potato tuber moth.

“…As a result, tuber quality is reduced and the risk of pathogen infection is increased [2][3][4]. Previous findings revealed no significant difference in the life history and fecundity of PTMs living on potato leaves and tubers [2,3], although a significant difference was found in the nutrient contents of potato leaves and tubers [5,6]. It remains unclear how PTMs adapt to these two different food sources.…”

Midgut microbiota diversity of potato tuber moth associated with potato tissue consumed

et al. 2020

Background: The potato tuber moth (PTM), Phthorimaea operculella (Zeller), is a worldwide pest that feeds on both the leaves and tubers of potato plants. PTM larvae can digest leaves, or tubers, resulting in serious damage to potato plants in the field and potato tubers in storage. To understand how midgut bacterial diversity is influenced by the consumption of these two tissue types, the symbiotic bacteria in the potato-feeding PTM midgut and the endophytic bacteria of potato tissues were analyzed. Results: At the genus level, the bacterial community composition in the PTM midgut was influenced by the tissues consumed, owing to their different nutrient contents. Escherichia_Shigella and Enterobacter were the most dominant genera in the midgut of leaf-feeding and tuber-feeding PTMs, respectively. Interestingly, even though only present in low abundance in leaves and tubers, Escherichia_Shigella were dominantly distributed only in the midgut of leaffeeding PTMs, indicating that specific accumulation of these genera have occurred by feeding on leaves. Moreover, Enterobacter, the most dominant genus in the midgut of tuber-feeding PTMs, was undetectable in all potato tissues, indicating it is gut-specific origin and tuber feeding-specific accumulation. Both Escherichia_Shigella and Enterobacter abundances were positively correlated with the dominant contents of potato leaves and tubers, respectively. Conclusions: Enrichment of specific PTM midgut bacterial communities was related to different nutrient levels in different tissues consumed by the insect, which in turn influenced host utilization. We provide evidence that a portion of the intestinal microbes of PTMs may be derived from potato endophytic bacteria and improve the understanding of the relationship between potato endophytic bacteria and the gut microbiota of PTMs, which may offer support for integrated management of this worldwide pest.
