Influence of relative humidity on the expression of twolined spittlebug (Hemiptera: Cercopidae) feeding injury in turfgrass genotypes

Damage caused by Diceraeus (= Dichelops) melacanthus in maize plants subjected to combinations: bioinoculation and imidacloprid seed treatment

“…An important observation was the higher content of chlorophyll a, indicating greater photosynthetic capacity, in the plants that received bioinoculation. Chlorophyll content can be an indication of plant resistance to pest infestation(Melo et al, 2018), as feeding insects generally reduce this component(Golan et al, 2015;Joseph & Jespersen, 2021). Thus, this study demonstrates for the first time that bioinoculation of maize with A. brasilense and B. japonicum, whether combined with imidacloprid or not, can help to mitigate photosynthetic damage caused by pests.In contrast, those plants treated with imidacloprid alone had a chlorophyll content similar to that of the control plants, indicating two possibilities: 1) neonicotinoids do not directly influence chlorophyll content(Preetha & Stanley, 2012); or 2) there is compatibility between rhizobacteria and imidacloprid (with the dose used in the present study).…”

“…In 2016, the two-lined spittlebug was first detected on Hawai ' i Island (Thorne et al 2017). The immature lifestages of this species are significant pests of turfgrass and pasturelands, where feeding causes wilting and phytotoxemia resulting in plant mortality (Byers and Wells 1966;Fagan and Kuitert 1969;Joseph and Jespersen 2021).…”
