Fig. 3 in Control of Diaprepes abbreviatus (Coleoptera: Curculionidae) with Steinernema riobrave (Rhabditida: Steinernematidae) in plasticulture Florida strawberry

Fig. 3. Progression of damage to strawberry plants (n = 13 per plot) when a central plant in each plot was infested with 4 late-instar Diaprepes abbreviatus. All plants in a plot received 1 or 2 soil applications of infective juvenile Steinernema riobrave (25 per cm2 in 50 mL water), 1 application of imidacloprid (Admire® Pro, 767 mL per ha), or water (control) on 16 and 22 Nov 2017, and plants were categorized weekly from pre-application (16 Nov) up to 4 wk post-application (14 Dec) using a rating scale of (1) healthy, (2) minor wilting, (3) major wilting, (4) mix of brown and green leaves, or (5) dead with all brown leaves. Strawberry plants were in raised, plasticulture earthen beds in research plots at the Gulf Coast Research and Education Center, Balm, Florida, USA.
