Early flowering field pea variety (Pisum sativum L.) as a trap crop for pea weevils (Bruchus pisorum L.)

Abstract

Bruchus pisorum L., is an economically important pest of field pea (Pisum sativum L.) crops worldwide, however, no fully effective methods (conventional, alternative) of its control exist now. To fill this knowledge gap, possibilities of trap cropping were tested in the years 2015–2017. Two field pea varieties differing in the start of flowering, and one spring barley variety, were used to design four different types of crops, that were compared in large plot trials (2.82 ha). It was hypothesized the females would prefer zones planted with early flowering variety for oviposition. In all three seasons, females placed more eggs on pods in the parts of plots planted with the early flowering variety, and positive aggregation of the eggs and infested seeds were recorded there too. In cases where the egg-laying period is shorter than 14–21 days, the early flowering variety located at the margins should serve efficiently as a trap crop.

Field and residential exposure of pesticides : Integrated risk analysis on terrestrial ecosystem and rural residents

“…For pest control purposes, the use of abamectin and chlorpyrifos can be replaced by clothianidin and pymtrozine; nicosulfuron could be an alternative option to eliminate weeds rather than using atrazine. Moreover, to mitigate the exposure risk of pesticides for non-target soil species and to maintain soil quality, integrated crop protection strategies that rely on multiple field measures, such as introducing natural enemies of pests, setting trap crops and applying mulches in multiple colors (Seidenglanz et al, 2022;Zhu et al, 2022), should be developed based on local cropping patterns.…”
