Pyridine compounds increase trap capture of Frankliniella occidentalis (Pergande) in a covered crop

The effect of pyridine compounds on the capture of thrips was examined in an Auckland New Zealand capsicum greenhouse in 2004 Yellow sticky traps were positioned just above the crop canopy in a rectangular array with 6 traps per compound and 6 control traps 2024 m apart and left for 24 h Most thrips found on traps were Frankliniella occidentalis (>99) Fourteen times more female F occidentalis were captured on traps with methyl isonicotinate or ethyl isonicotinate than on controls Sticky traps treated with methyl 4pyridyl ketone also caught more female F occidentalis than controls (45) Sticky traps with methyl isonicotinate caught more male F occidentalis (up to 52) than controls Ethyl2chloropyridine4carboxylate and ethyl nicotinate did not increase trap catches of either sex The results demonstrated that selected pyridine compounds have the potential to improve trap capture of F occidentalis in a covered crop

Yellow Sticky Traps

Strawberry lethal yellows (SLY) is a phytoplasma disease that affects strawberry plants in New Zealand and Australia Although it has been established that this phytoplasma (Candidatus Phytoplasma australiense) is responsible for causing diseases in a number of other plant hosts an insect responsible for its spread still remains to be determined To identify potential insect vectors yellow sticky traps were established at two properties in the Bay of Plenty from planting (early October 2001) until harvest (May 2002) Leafhoppers caught in the traps until March 2002 and by sweepnetting the surrounding habitats in February were identified and tested for the presence of phytoplasma using Polymerase Chain Reaction (PCR) Arawa variegata and Recilia hospes (both Cicadellidae) were the commonest leafhoppers trapped Phytoplasma was detected in first and second generation A variegata in October and February respectively and in second generation R hospes in February The implications of this work for future SLY studies is discussed

Yellow Sticky Traps

Yellow bristle grass is a highly invasive annual C4 pasture weed that has spread rapidly through many New Zealand dairying regions via seed dispersal. Seven trials were conducted on roadsides infested with yellow bristle grass to evaluate natural and mower-assisted dispersal. To trap seeds, yellow sticky traps were laid out at various intervals both perpendicular to and parallel to the road. Traps were in place for 24 h in the four natural dispersal trials but only for the event in the mowing trials. Seeds on the retrieved traps were counted and the seeds caught in the mower estimated. For natural dispersal, 90% of seeds fell within 0.5 m. When mown, 90% of the seeds fell within 2 metres in the direction of mowing and 80% within 20 cm in the perpendicular direction. More importantly, a small percentage of dispersed seeds were caught in the mower and presumably could subsequently fall off anywhere. Mowing mature yellow bristle grass on the roadside will result in accelerating seed dispersal along the roadside for many metres and potentially many kilometres.

Bactericera cockerelli (the tomatopotato psyllid; TPP) and associated insects were monitored weekly in unsprayed potatoes at Pukekohe by using yellow sticky traps and sampling plants from late July 2009 until mid March 2010 TPP adult catches and egg and nymphal infestations were absent or low until mid December Other exotic and native psyllid species dominated trap catches until TPP populations increased markedly in mid January and peaked at 120 adults per trap in late February with egg numbers reaching 520 per plant a week later TPP nymphs peaked at 260 per plant in early February Micromus tasmaniae (brown lacewing) was common in spring and summer but Melanostoma fasciatum (small hover fly) became the dominant predator peaking at 162 eggs and 35 larvae per plant in mid January Naturally occurring predators appear to be important biological control agents of aphids small caterpillars and probably TPP on potatoes at Pukekohe

AbstractTests were performed to determine whether combining two thrips lures, ethyl nicotinate (EN) and ethyl isonicotinate (EI), in the same water trap increased the numbers of New Zealand flower thrips (NZFT), Thrips obscuratus Crawford, and onion thrips, T. tabaci Lindeman (Thysanoptera: Terebrantia: Thripidae), caught in the field relative to traps with a single lure. Traps with both lures (1:1 ratio; mixture or separate adjacent vials) caught 5–9 times more female onion thrips (thelyotokous populations are the most prevalent in New Zealand) than traps with EN only (P<0.001), but in similar numbers to traps with EI only. Traps with both lures caught 2–3 times as many male and female NZFT than traps with EI only, but in similar numbers to traps with EN only. Thus, a combination of the two lures in one trap could be used to detect and monitor flying onion thrips and NZFT simultaneously.

Yellow Sticky Traps

AbstractThe placement of yellow sticky traps in relation to greenhouse-grown tomato plants affected the number of greenhouse whiteflies captured on traps. Whiteflies were caught on traps close to the ground when the traps were 1.0 m or more from plants, and were caught on traps level with the point from which they started flight when the traps were 0.5 m from plants. Traps 1.0 m from plants primarily caught whiteflies less than 5 days old, and trap catches were not correlated with numbers on plants; traps 0.5 m from plants caught whiteflies of all ages, and trap catches were correlated with numbers on plants. These results suggest that under field conditions greenhouse whiteflies would behave much like other species of whitefly, and would tend to be caught on traps close to the ground. In greenhouses, monitoring traps should be placed close to and slightly below the tops of the plants. Trap counts could be treated as samples from individual plants and used to make an estimate of population size in the greenhouse. Traps placed further from the plants monitor flight activity only.
