Expression patterns of ASR1 , PIN2, and PAL genes in tomato and eggplant after treatment with different inducers Int. J. Trop. Insect Sci. (IF 0.536) Pub Date : 2021-03-02 Fatemeh Jafarbeigi, Mohammad Amin Samih, Hossein Alaei
Salicylic acid (SA) and β-aminobutyric acid (BABA) are signaling compounds that regulate a large number of defense responses in plants after exposure to the biotic and abiotic stresses. The antagonistic fungus Trichoderma harzianum is well-known as a potential biocontrol agent that also induces defensive responses. In the present study, we tested the up- and down-regulation of defense responses of

Exploring community knowledge, perception and practices of entomophagy in Kenya Int. J. Trop. Insect Sci. (IF 0.536) Pub Date : 2021-03-02 Elizabeth Siago Kusia, Christian Borgemeister, Chrysantus M. Tanga, Sunday Ekesi, Sevgan Subramanian
In recent years, community’s perceptions and acceptance of edible insects as novel foods has gained momentum worldwide. Despite the importance of entomophagy in Kenya, little information exists on knowledge, perceptions and practices of edible insects among different communities. This study seeks to address this information gap by conducting surveys on edible insects in Kenya. Semi-structured questionnaires

A preliminary study on the juvenile stages of Tenebrio molitor Linnaeus, 1758 ( Coleoptera : Tenebrionidae ) and Sphenarium purpurascens Charpentier, 1842 ( Orthoptera : Pyrgomorphidae ) as exploitable nutraceutical resources Int. J. Trop. Insect Sci. (IF 0.536) Pub Date : 2021-02-21 Arijit Ganguly, Jose Manuel Pino Moreno
Being rich in nutrients insects are potential nutraceutical resources. In the present study, we have selected the 8th instar larval stages of Tenebrio molitor and 5th instar nymphal stages of Sphenarium purpurascens, because these are the most sought after stages in the edible insect market in various states of the Mexican Republic. We have estimated their proximate composition and mineral contents
