“…Helicoverpa armigera has been successfully trapped by wire cone, dry funnel (Kehat & Greenberg 1978), and delta (sticky) traps baited with sex pheromone in Australia (Baker et al 2011;Fitt et al 1989;Wilson & Morton 1989), Egypt (Salem et al 2008), Greece (Mironidis et al 2010), Hungary (Dömötör et al 2007;Keszthelyi et al 2011), andIndia (Basavaraj et al 2013;Srivastava 2010). Sex pheromone traps, along with light traps, were successfully used to document new distributions of H. armigera in parts of Australia where populations were not thought to exist (Fitt et al 1995).…”

“…In pest management, pheromone-based monitoring is to a great extent focused on indications of abundance in relation to economic injury thresholds. Most of these studies deal with future predictions of abundance and/or damage levels based on host and pest phenology and weather conditions (Anderson et al 2012; Damos and Savopoulou-Soultani 2010; Dömötör et al 2007; Hayes et al 2009; Mori et al 2014). Nevertheless, there are a considerable number of studies that relate trap catches to abiotic conditions, which would constitute a platform for normalizing catches between different occasions (Williams et al 2008).…”

As global biodiversity declines, biodiversity and conservation have become ever more important research topics. Research in chemical ecology for conservation purposes has not adapted to address this need. During the last 10–15 years, only a few insect pheromones have been developed for biodiversity and conservation studies, including the identification and application of pheromones specifically for population monitoring. These investigations, supplemented with our knowledge from decades of studying pest insects, demonstrate that monitoring with pheromones and other semiochemicals can be applied widely for conservation of rare and threatened insects. Here, I summarize ongoing conservation research, and outline potential applications of chemical ecology and pheromone-based monitoring to studies of insect biodiversity and conservation research. Such applications include monitoring of insect population dynamics and distribution changes, including delineation of current ranges, the tracking of range expansions and contractions, and determination of their underlying causes. Sensitive and selective monitoring systems can further elucidate the importance of insect dispersal and landscape movements for conservation. Pheromone-based monitoring of indicator species will also be useful in identifying biodiversity hotspots, and in characterizing general changes in biodiversity in response to landscape, climatic, or other environmental changes.

“…Thus, generations developing without diapause can play an important role in forming multitudinous flight peaks from the middle of summer in Hungary. Therefore, pesticide applications in the field have to be synchronized with the peaks and the multitudinous appearance of L 1 (first instar) larvae (Dömötör et al 2007). …”

To determine the cotton bollworm migrating population rate in Hungary, we examined the weights and the front wing morphological feautures of trapped moths. We used sex pheromone traps to monitor field populations during the maize vegetation cycle period in 2008. We examined moths trapped at various times, and measured their body mass (m) and morphological features, namely the front wing quotient (fWQ = quotient of length of front wing/width of front wing), modified wing loading (WL = weight of moth/surface of front wing), and the relative thorax size (RTS = width of thorax/width of head). The data were analysed by Student t-test, anterior wing abrasion and darkness were analysed by a Adobe Photoshop 7.0 software. The Hungarian appearance of three cottom bollworm generations in 2008 was also observed. Based on the examined morphological features we found regularity in body mass, front wing quotient and modified wing loading changes during the flight period. The specimens trapped in the first and third part of the flight period had lower body mass, larger wing surface, longer wings and more favourable modified wing loading than the specimens trapped in the middle of the flight period. The abrasion and colour of the anterior wings of cotton bollworms were concordant to morphometric investigations. The abrasion in darker spots E1 and E3 clearly showed a more intensive usage of the wings in case of specimens trapped at the beginning and at the end of the flight period.
