Tetrigidae is a caeliferan family of Orthoptera constituting a diverse and relatively ancient lineage of small Orthopterans, which has its greatest diversity in tropical and subtropical areas. However, to date, few studies have been conducted on the identification and description of Tetrigidae species in Ethiopia, and even fewer molecular data are available. Hence, we performed the first species delimitation study via DNA barcoding of species belonging to the genera Paratettix, Leptacrydium, Dasyleurotettix, and M…

This study aimed to analyze farmers’ perceptions of maize production constraints and determine the effects of push–pull technology (PPT) on crop yield, pest control, and improving soil fertility status. Increasing fertilizer prices and pesticide prices, FAWs (fall armyworms) and stemborers, declining soil fertility, and drought are the main maize production constraints in the area. Seventy percent of the respondents indicated that an increase in input prices such as those of fertilizer and seeds is the major const…

Summary Maize is an important cereal crop in sub-Saharan Africa (SSA). Plant-parasitic nematodes significantly impact maize production. However, research on maize nematodes in SSA is limited. The current study aimed to assess the occurrences and densities of nematodes associated with maize and to assess the correlation of some soil physicochemical properties with nematodes in southern and southwestern Ethiopia. One hundred and eighty-six soil and root samples were collected from 62 maize fields (31 from Hawassa Zu…

Bacillus firmus, commercial WP formulation (BioNem) was evaluated against root-knot nematode, Meloidogne incognita on tomato plants under field conditions of Dire Dawa and Haramaya University (Ethiopia). Studies were conducted with the objectives to find out the effect of BioNem on nematode infestation and plant growth/yield of tomato and to compare two methods of application of BioNem for the control of root-knot under field conditions. Soil application of BioNem at transplanting in the field @ 200 and 400 kg/ha …

Abstract Background Chickpea ( Cicer arietinum L.) is one of the most principally important legume crops in Ethiopia. Its production is mainly constrained by insect pests. Dissemination of updated information on its status and addressing alternative management options are important. Main body This article reviews the research status of the cotton bollworm ( Helicoverpa armigera ) and Azuki bean beetle ( Callosobruchus chinensis ) in chickpea, focusing on their distributions, host range, nature of the damage, biolo…
