“…Previous research on the pesticidal plant species used for pest control in this study all have reported bioactivities against insects, parasites, bacteria and fungi (Ganjian et al, 1983 ; Jisaka et al, 1992 ; Lina et al, 1992 ; Pereira et al, 1997 ; Gu et al, 2002 ; Rabe et al, 2002 ; Ogendo et al, 2003 ; Adedire and Akinneye, 2004 ; Boeke et al, 2004 ; Omolo et al, 2004 ; Kawuki et al, 2005 ; Koona and Dorn, 2005 ; Viljoen et al, 2005 ; Koona et al, 2007 ; Ambrósio et al, 2008 ; Asawalam et al, 2008 ; Mujovo et al, 2008 ; Oyewole et al, 2008 ; Bagnarello et al, 2009 ; Chukwujekwu et al, 2009 ; Deng, 2009 ; Gadzirayi et al, 2009 ; Koul and Walia, 2009 ; Madzimure et al, 2011 ; Tesch et al, 2011 ; Chagas-Paula et al, 2012 ; Bartolome et al, 2013 ; Ellse and Wall, 2013 ; Nhamo et al, 2013 ; Utono et al, 2014 ; Green et al, 2017 ; Kamanula et al, 2017 ); however, none of these works have investigated the effects of their application on field crop performance or tritrophic impact. Much is also known about the phytochemistry of the six species evaluated.…”
