Suppression of indigo bush with pod pests

Abstract

The recorded seed predators of Amorpha fruticosa L., indigo bush weevils and pteromalid wasps, were the subject of laboratory and field research studies in the period from 2006 to 2011. Sample analyses were carried out on more than 30 localities in Serbia with the aim of measuring the summarized pre-dispersal and post dispersal predation preferences. The percentages of the total pre-dispersal (max≈33%) and post-dispersal re-infested material (over 95%), make these insects serious candidates for host-plant suppression. Their bionomics were monitored through continuous collection, dessection and observation of infested seeds, in correlation with environmental parameters, especially water-level fluctuations in endangered forests.

Floristic diversity, composition and invasibility of riparian habitats with Amorpha fruticosa : A case study from Belgrade (Southeast Europe)

“…It was brought to the Balkan Peninsula at the beginning of the twentieth century when it started to colonise alluvial forests and other habitats in large lowland river valleys (Gagić-Serdar et al, 2013), seriously threatening the ecological balance of native ecosystems (Krpan and Benko, 2009). Although Weber and Gut (2004) assessed that A. fruticosa represents a potentially invasive plant species in central Europe, nowadays it is one of the most dangerous invasive neophytes spreading rapidly in many countries and cities of south-eastern Europe as well (Anastasiu et al, 2007;Grbić et al, 2007;Pedashenko et al, 2012;Anačkov et al, 2013).…”

“…As it can reproduce both generatively and vegetatively, it is growing faster than most forest-cultural species (Tucović and Isajev, 2000;Gagić-Serdar et al, 2013). Amorpha fruticosa aggressively penetrates into newly invaded sites, where it establishes permanently (Radulović et al, 2008).…”

New Records of Bruchidius Spermaphagous Species in Albizia julibrissin and Laburnum anagyroides and Their Parasitoid Complex in Serbia

“…Their bionomic were monitored by conti-nuous infested seed collecting, its disection and observed also in correlation with host specificity ranged from monophagy (at least ecological monophagy) to possible oligophagy. On the basis of presence/ absence data we tested the null hypothesis assuming that plant taxa and seed consuming weevil species form congruent phyletic relations at the species level [7,13]. For this purpose, pods of L. anagyroides were collected in April 2012 and 2014, than in 2013 during May and August and in April 2014; 300 seeds were also extracted and observed for emergence holes during spring, April, May and June in 2014.…”

A review on invasive false indigo bush (Amorpha fruticosaL.): Nuisance plant with multiple benefits

“…On some occasions, together with the introduction of A. fruticosa , it has been followed by the introduction of the predator beetle, for example, in Japan and in the Russian Far East (Kuprin et al, 2018 ; Tuda et al, 2001 ). Finally, research carried out by Gagić‐Serdar et al ( 2013 ) proved the potential of A. pallidipennis as a biological control agent of A. fruticosa .…”
