Effect of different concentrations and frequency of replacement of pheromone lure on moth catches of T. absoluta in tomato during rabi, 2016
Source publication
Field studies were conducted to evaluate the efficacy of pheromone trap types, height of trap erection, pheromone lure concentrations and replacement period on trap catches of Tuta absoluta in farmers' field during rabi, 2016-2017 in Piler and Kalikiri mandal of Chittoor district, Andhra Pradesh. Among the three trap types, Delta traps installed at...

... lure concentrations and replacement period evaluation The pheromone lure efficacy influences on fluctuation of moth catches of T. absoluta and results were presented in Table 2 and Figure 2. The obtained data revealed that treatment T 4 (two mg septum replaced for every 15 days) recorded significantly higher moth catches (41.36 moths/trap) than all other treatments. ...

The spruce bark beetle has two flights on year, in Nădrag-Padeş conditions. The first flight is produced in springtime and second one is produced in summertime. The second flight is prolonged until in autumn. For monitoring I have used traps (type Barieră for Ipidae and type Theysohn) baited with aggregative synthetic pheromones. The pheromones whi...

To optimize a logistics distribution path under capacity and time window constraints, a mathematical model of the problem is first developed in this study, with the...
Click beetle pests (Elateridae: Agriotes sp.) of 24 sites in different regions of Hungary were studied in 2011. A. brevis, A. sputator, A.obscurus, A. lineatus, A. rufipalpis and A. ustulatus were sampled by pheromone traps in maize fields. During the study 65895 beetles werecaught. A. ustulatus and A. sputator were the most abundant species. Beyon...

... This will suppress population increase before harvesting. The relatively high numbers of m/t/w that were observed from the beginning of winter seasons might be considered as extend from summer seasons due to relatively high larval population by the end of earlier summer (Portakaldali et al. 2013;Bayram et al. 2014;Cherif and Kaouthar 2017;Awad et al. 2018;Venkataramanaiah et al. 2018). ...
The tomato leafminer (TLM), Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), is a devastating insect pest worldwide. As an invasive species, its spread depends on the suitability of biotic and abiotic factors. We documented the prevalence and population dynamics of TLM on tomatoes and other host plants along the Nile Delta region in Egypt. For the first time, we recorded Black nightshade as an alternative host plant. In tomato fields, males and immature stages fluctuated with crop phenological cycle, time, seasons and had 2–3 peaks/season. The effect of temperature and relative humidity on population dynamics is plant stage and season dependent. Visual inspection and trapped males were relevant indicators for population size. Tuta absoluta infested tomato leaves, fruits, and steams, with preference for leaves. Three predators; Nesidiocoris tenuis (Reuter), Macrolophus pygmaeus (Rambur) (Hemiptera: Miridae) and Chrysoperla carnea (Steph) (Neuroptera: Chrysopidae) and an egg parasitoid, Trichogramma achaeae (Nagaraja & Nagarkatti) (Hymenoptera: Trichogrammatidae) were recorded. Natural enemies corresponded to pest population fluctuations with higher incidence during the middle of the season. Activities of Tr. achaeae and N. tenuis were correlated with egg population in summer while M. pygmaeus correlated with larval population in winter. Exploring these ecological aspects provides key elements for pest control programs.
