Abstract Cost efficiency in biosecurity surveillance is vital, and the ability to survey for multiple pest species using just one trap therefore highly appealing. The Psylloidea, or plantlice, contain significant horticultural pest species that act as vectors for a number of deleterious plant bacteriums. We examine the efficacy of using two different coloured sticky traps, and two lure types on the general Psylloidea and Pentatomoidea fauna, and a target extant pest psyllid; tomato potato psyllid (TPP) Bactericera cockerelli (Šulc). Specifically, we test the effect of lure (no lure, Asian citrus psyllid ACP lure, brown marmorated stink bug BMSB lure, combined lures), sticky trap color (green vs yellow), and sentinel plant (tomato vs citrus) on psyllid and stink bug species in 104 urban backyards across Perth, Australia. We found that tomato sentinel host plants and green traps significantly increased the capture rate of TPP, but that all lures decreased the capture of TPP. Green traps also increased the capture rate of all other Psylloidea. Although BMSB lures reduced TPP capture, these lures increased abundances of other Psylloidea and the pest stinkbug Plautia affinis (Dallas) on traps. Thus, our experiment demonstrates that increased efficiencies can be gained with combination traps and lures for particular groups, provided that they have been tested on focal organisms in the first instance, as reactions to non-target lures are unpredictable and species specific.

Sulphur is mainly used as a fungicide but is known to have insecticidal properties against some insect pests A series of laboratory studies was conducted to assess its effect on the tomato potato psyllid (Bactericera cockerelli; TPP) a recently established pest species in New Zealand that transmits the bacterium Candidatus Liberibacter solanacearum (Lso) Short assays (8805; 24 h) using dipped leaves indicated that fresh sulphur residues had no discernible impact on TPP settlement patterns or onleaf behaviour However longer assays (8805; 72 h) using whole plants indicated that sulphur residues can disrupt egglaying behaviour but the effect was dependent on the assay design In 72 h choice assays TPP laid fewer eggs on plants sprayed with sulphur compared with control plants In nochoice assays sulphur residues did not consistently reduce egglaying Together these results suggest that sulphur may slow the buildup of TPP populations within crops by deterring egglaying However the lack of repellence or antifeeding properties means that sulphur treatments alone may not be sufficient to prevent the transmission of Lso by TPP

The tomato potato psyllid Bactericera cockerelli (TPP) and the bacterium it vectors Candidatus Liberibacter solanacearum (CLso) are collectively responsible for significant economic losses across New Zealands horticulture industry Crop host plants of TPP include potatoes tomatoes capsicums/ chilli peppers tamarillos and tobacco along with lessobvious species outside the Solanaceae family such as kumara (Convolvulaceae) Most of these plants are shortlived summer annuals which raises the question what happens to TPP when crops are absent Many less conspicuous noncrop plants also play host to TPP some of which are perennial and therefore present yearround potentially acting as reservoirs of both TPP and CLso in the absence of a crop A pilot study in 2012 and subsequent vegetation surveys in Canterbury and Hawkes Bay in 201314 confirmed the presence of all TPP life stages on multiple noncrop species yearround in both areas despite adverse climatic events such as winter frosts and snowfall These results have farreaching impacts on the way growers should manage the borders surrounding their crops and their land in the offseason

Adult and nymphal life stages of the tomato/potato psyllid (Bactericera cockerelli; TPP) cause damage to the host plants and transmit the bacterial pathogen Candidatus Liberibacter solanacearum This leads to reduced crop yield and ultimately the premature decline and death of the infected plant The efficacy of 11 insecticides was tested against nymphal and adult stages of TPP Residues of abamectin oil and bifenthrin were the most effective at reducing adult TPP up to 3 days after treatment while thiacloprid spiromesifen imidacloprid spinetoram and azadirachtin were slightly toxic Residues of buprofezin oil pyrethrin oil and mineral oil had no effect on adult mortality Nymphal life stages were best controlled with abamectin oil spirotetramat bifenthrin and spiromesifen

Abstract Understanding factors that affect the population dynamics of insect pest species is key for developing integrated pest management strategies in agroecosystems. Most insect pest populations are strongly regulated by abiotic factors such as temperature and precipitation, and assessing relationships between abiotic conditions and pest dynamics can aid decision-making. However, many pests are also managed with insecticides, which can confound relationships between abiotic factors and pest dynamics. Here we used data from a regional monitoring network in the Pacific Northwest United States to explore effects of abiotic factors on populations of an intensively managed potato pest, the potato psyllid (Bactericera cockerelli Šulc), which can vector Candidatus Liberibacter psyllaurus, a bacterial pathogen of potatoes. We assessed effects of temperature on psyllid populations, and show psyllid population growth followed predictable patterns within each year, but there was considerable variation across years in psyllid abundance. Examination of seasonal weather patterns suggested that in 2017, when psyllid populations were less abundant by several orders of magnitude than other years, a particularly long and cold period of winter weather may have harmed overwintering populations and limited population growth. The rate of degree-day accumulation over time, as well as total degree-day accumulation also affected trap catch abundance, likely by mediating the number of psyllid generations per season. Our findings indicate that growers can reliably infer the potential magnitude of risk from potato psyllids using monitoring data, date of first detection, seasonal weather patterns, and population size early in the growing season.

AbstractThe brown marmorated stink bug, Halyomorpha halys (Stål, 1855) (Hemiptera: Pentatomidae), is an invasive harmful pest species due to its economic losses. Its wide host range and continuous movement make its control difficult with insecticides. Biological control has recently gained importance due to the negative aspects of chemical control. The study evaluated the biological control tools by testing the entomopathogens against the pest by 11 bacteria strains and 1 fungal isolate. Brevibacillus, Bacillus, Pantoea, Vibrio, Pseudomonas, and Beauveria were tested against the nymphs of H. halys under controlled conditions. All applied entomopathogens had potentials for controlling H. halys. Mortality rates of 75 and 100% were obtained by the bacteria strains and 76.19% by the fungus, B. bassiana. Successfully reaching a 100% control rate, the bacterial isolates of the Bacillus cereus GC subgroup B and Pantoea agglomerans GC subgroup were recorded to have a greater potential than the others.

During 200708 the tomato potato psyllid (TPP Bactericera cockerelli) was observed in outdoor tomato and potato crops in Hawkes Bay Many crops were heavily infested resulting in severe yield losses and in some cases crop abandonment Since then growers have been proactive in plant monitoring and sticky trap use but these methods are expensive and quite often a calendar spray programme is begun once the first adult TPP have been observed in traps It has been proposed that 980 degreedays (DDs) from 1 July is used as an indicator of when TPP numbers are about to increase rapidly in North Island crops This study describes the application of 980 DDs to recent sticky trap data from Hawkes Bay For most sites 980 DDs occurred just before rapid increases in adult TPP numbers However there were a small number of sites where this was not so The presence of noncrop TPP host plants bordering these sites may explain rapid increases in TPP trap catches well before reaching 980 DDs

Dispersal Period

The brown marmorated stink bug, Halyomorpha halys (Heteroptera: Pentatomidae), is regarded as one of the world's most pernicious invasive pest species, as it feeds on a wide range of economically important crops. During the autumn dispersal period, H. halys ultimately moves to potential overwintering sites, such as human-made structures or trees where it will alight and seek out a final overwintering location, often aggregating with other adults. The cues used during this process are unknown, but may involve vibrational signals. We evaluated whether vibrational signals regulate cluster aggregation in H. haly s in overwintering site selection. We collected acoustic data for six weeks during the autumn dispersal period and used it to quantify movement and detect vibrational communication of individuals colonizing overwintering shelters. Both movement and vibrational signal production increased after the second week, reaching their maxima in week four, before decaying again. We found that only males produced vibrations in this context, yet there was no correlation between movement and vibrational signals , which was confirmed through playback experiments. The cues regulating the formation of aggregations remain largely unknown, but vibrations may indicate group size.

Understanding the interaction between insects and microclimate can be essential in order to plan informed and efficient treatments against agricultural pests. Microclimatic factors such as humidity and temperature can influence the population dynamics of the invasive agricultural pest Halyomorpha halys, the brown marmorated stink bug. The aim of this work was to evaluate the level of transpiration of H. halys in dry, normal and humid microclimates according to the sex, physiological conditions and developmental stage of individuals. Water loss during diapause and the effect of population density on insects’ transpiration were also assessed, as were the nutritional preferences of adults upon exiting diapause. Our data demonstrate that microclimatic conditions significantly influence the transpiration of this pest species. The effect of sex and feeding status on insects’ water loss is marked, while population density does not influence water loss in diapausing individuals. The first nutritional need of the overwintering generations is represented by hydration, likely due to the water loss during diapause.

AbstractHalyomorpha halys Stål (Hemiptera: Pentatomidae), the brown marmorated stink bug (BMSB), has been intercepted numerous times in Canada, and overwintering BMSB adults have been reported by homeowners. However, established breeding populations were not detected before 2012. Here we report the occurrence of established populations of BMSB in southern Ontario, Canada and describe habitats, host plants, and collection efforts from 2012 to 2013. Tracking the phenology and spread of this pest in Ontario is critical for the development of integrated pest management strategies to prevent severe economic damage due to this pest.
