Abstract There is a paucity of information on the edible grasshoppers and their host plants in East Africa. This study adopted morphological and molecular analysis to identify edible grasshoppers in Kenya and Uganda. The associated host plants were identified through molecular analysis of the gut contents of the grasshoppers. The cytochrome b and 16s gene primers were used for grasshopper DNA analysis; while matK gene primers were used for plant DNA analysis. All long-horned grasshoppers sampled were identified as Ruspolia differens (Serville) (Orthoptera: Tettigonidae); whereas short-horned grasshoppers were identified as Acanthacris ruficornis (Fabricius) (Orthoptera: Acrididae) and Cyrtacanthacris tatarica (L.) (Orthoptera: Acrididae). Host plants of A. ruficornis were Achyranthes aspera (L.), Centella virgata L.f. Drude, Digitaria gayana (Kunth), Galinsoga quadriradiata Ruiz and Pavon, and Triumfetta pilosa Roth; whereas those of C. tatarica were Alysicarpus rugosus (Willd.) DC and Teramnus uncinatus (L.) SW. Host plants of R. differens were Ageratum conyzoides (L.), Citrus depressa Hayata, Cynodon dactylon (L.), D. gayana, Eragrostis mexicana Hornem, Eucalyptus saligna SM., Indigofera arrecta Hochst. ex A. Rich., Persicaria nepalensis (L.), and Sorghum halepense (L.). Information on the host plants of edible grasshoppers can help in the development of their mass rearing protocols.

东非食用短角和长角蚱蜢及其寄主植物的鉴定

摘要 关于东非可食用蚱蜢及其寄主植物的信息很少。本研究采用形态学和分子分析方法对肯尼亚和乌干达的可食用蚱蜢进行鉴定。通过对蚱蜢肠道内容物的分子分析，确定了相关宿主植物。细胞色素b和16s基因引物用于蝗虫DNA分析；而 matK 基因引物用于植物 DNA 分析。采样的所有长角蚱蜢均被鉴定为 Ruspolia differentens (Serville) (Orthoptera: Tettigonidae)；而短角蚱蜢被鉴定为 Acanthacris ruficornis (Fabricius) (Orthoptera: Acrididae) 和 Cyrtacanthacris tatarica (L.) (Orthoptera: Acrididae)。A. ruficornis 的寄主植物是 Achyranthes aspera (L.)、Centella virgata Lf Drude、Digitaria gayana (Kunth)、Galinsoga quadriradiata Ruiz 和 Pavon 和 Triumfetta pilosa Roth；而那些 C. tatarica 是 Alysicarpus rugosus (Willd.) DC 和 Teramnus uncinatus (L.) SW。R. differentens 的寄主植物是 Ageratum conyzoides (L.)、Citrus depressa Hayata、Cynodon dactylon (L.)、D. gayana、Eragrostis mexicana Hornem、Eucalyptus saligna SM.、Indigofera arrecta Hochst。ex A. Rich.、Persicaria nepalensis (L.) 和 Sorghum halepense (L.)。有关可食用蚱蜢寄主植物的信息有助于制定其大规模饲养方案。Eragrostis mexicana Hornem，Eucalyptus saligna SM.，Indigofera arrecta Hochst。ex A.
