Abstract:

Abstract Fall and spring prescribed fires were conducted in two Pennsylvania sugarbushes to evaluate the effects of fire on the emergence of overwintering pear thrips from the soil. Soil temperatures and numbers of emerging pear thrips were monitored in the burned and unburned areas at 2-day intervals from mid-March until early May 1991. At both sites, fall fires accelerated soil warming, resulting in an earlier peak emergence of the thrips. The fall and spring fires also significantly reduced the number of thrips emerging from the soil. These results suggest the potential for controlling pear

Abstract:

The relationship between budburst phenology and damage by the pear thrips (Taeniothripsinconsequens (Uzel) (Thysanoptera: Thripidae)) to sugar maple (Acersaccharum Marsh.) foliage was investigated in two studies. In the first study, seedlings in cages were exposed to adult thrips at different stages of budburst. Compared with uninfested control seedlings, introduction of five adult thrips per bud reduced total leaf area and average leaf size, and caused chlorosis, tattering, and cupping of leaves. Leaf area reduction and damage symptoms were greater for seedlings exposed to thrips when leaf ma

Abstract:

AbstractWidespread defoliation of sugar maple stands due to pear thrips, Taeniothrips inconsequens (Uzel), feeding occurred in Massachusetts in 1987 and 1988. To assess the role of tree health as a possible cause of these outbreaks, an experiment was conducted in sugar maple stands in Massachusetts in 1990. Sleeve cages were placed on mature sugar maples and stocked with adult female pear thrips to determine the relation between root starch reserves (an index of tree health) and thrips fecundity. The experiment was run at four sites, assessing both root starch levels and thrips fecundity on in

Sugar maple (Acersaccharum Marsh.) seedlings were exposed to either cool (11.9 °C) or warm (18.2 °C) temperatures in the presence or absence of adult pear thrips (Taeniothripsinconsequens Uzel) during bud burst and early spring growth. Time required for spring stem elongation was shorter at the warm temperature than at the cool temperature. Thrips feeding reduced height, leaf area, and seedling dry weight at both temperatures, and reductions were greater at the cool temperature than at the warm temperature. The results indicate that cool temperatures that slow bud burst promote pear thrips dam

Abstract:

Recent damage to sugar maple, Acer saccharurn Marsh., by pear thnps, Taeniothrips inconsequens, in the northeast of the United States and adjacent parts of Canada has led to much research on this pest (Teulon et al. 1993; Teulon and Cameron 1996; Parker and Skinner 1997). A detailed description of the univoltine pear thrips' life history is reported in Teulon et al. (1998). Although T: inconsequens is the dominant species in sugar maple, other thrips may also be important as herbivores, detritivores, or predators and need to be taken into account in sampling or monitoring programmes.

Reduction in BAI of declined compared with healthy trees was first evident following a series of defoliations and summer droughts in the mid-1960s and early 1970s.

AbstractShortly after its invasion into Europe, the western flower thrips, Frankliniella occidentalis (Pergande), became a more severe pest of greenhouse crops than the onion thrips, Thrips tabaci Lindeman. To test whether this differential pest status was due to a larger capacity of population increase, a comparative life history study was carried out on cucumber (Cucumis sativus cv. Corona). Experiments at 25°C showed that the egg-to-egg period of F. occidentalis was shorter, but its peak ovipositional rate was lower and its offspring sex ratio more male biased.

Abstract:

Abstract The short-range diurnal dispersal pattern of adult western flower thrips Frankliniella occidentalis (Pergande), in relation to spatial distribution of French beans, was determined in the field. A total of 1200 adult female F. occidentalis were released on 60 French bean plants with 20 adult thrips per plant at the central release point of 3.14 m2. Dispersal was determined in terms of the number of thrips recorded on French beans planted on concentric circles at 0.9, 1.8, 3.6, 7.2 and 14.4 m radii from a circular central release point for five days. Results indicated that there was a s

Abstract:

Green lacewings (Neuroptera: Chrysopidae) are commercially available augmentative biological control agents. Despite centuries of recognition as beneficial insects (Darwin 1800), scant information can be found describing what lacewing larvae prey upon in the field when several different prey species are present (New 1975). I assessed the types of prey that Chrysoperla plorabunda (Fitch) larvae consume when they are released on peas, Pisum sativum L. (Fabaceae), in western Washington. In 1997, two field assistants and I made observations at three sites: the Rent's Due Ranch (RDR: 48°14′N, 122°2

Abstract:

Abstract In Poland chemical control of thrips in pea crops currently relies on insecticides with several modes of action, including pyrethroids (deltamethrin, cyhalothrin, cypermethrin) and neonicotinoids. The first insecticide treatment is recommended to be applied during the full bloom of pea plants and the second two repeated at intervals of 7 days. Field experiments were carried out at the Experimental Station in Mydlniki (near Kraków, southern Poland) over two years (2011 and 2012). Acetamiprid (neonicotinoid) (trade name Mospilan 20 SP) was used to control thrips on peas in the experimen

Abstract:

ABSTRACT Peanut (Arachis hypogaea L.) is a legume and requires nodulation by Bradyrhizobia to convert atmospheric N into a plant usable form. Peanut inoculants place large volumes of viable Bradyrhizobia near the emerging root of the plant to infect it ensuring N-fixation. Peanut seedlings are susceptible to feeding by thrips (Thysanoptera: Thripidae), which transmit Tospovirus leading to tomato spotted wilt (TSW) and can result in yield decline. Phorate is a common in-furrow insecticide used to reduce thrips feeding on the plants, and hence reduce the risk of TSW infection. However, placing p
