The susceptibility of onion thrips, Thrips tabaci to Heterorhabditis indicus.

Communications in agricultural and applied biological sciences, 2007
The potential of the entomopathogenic nematode, Heterorhabditis indicus against Thrips tabaci was tested on foliage and in soil at three concentrations. Soil treatment was more effective than the foliar treatment. At 1.5 million nematodes/m2, nearly 70% mortality was achieved with soil application whereas a similar dose applied to the foliage gave only

Population Dynamics of Thrips tabaci in Onion

Indian Journal of Entomology
Thrips tabaci Lindeman (onion thrips) have become a serious pest threatening onion cultivation. The present study investigated the impact of three planting dates on T. tabaci incidence on onion (Giza 20 variety) for two years (2021-22 and 2022-23). The findings revealed that the T.

Sequential Sampling for Thrips tabaci on Onions

1995
A binomial sequential sampling procedure based on the presence of five or more Thrips tabaci per onion was as precise as Iwao’s sequential sampling method that requires counting all thrips present. Acceptance boundaries were calculated for economic thresholds of 0.9 and 2.2 thrips per leaf and the plans were validated in fields containing 0.01 to 32.33

Plant odours with potential for a push–pull strategy to control the onion thrips, Thrips tabaci

Entomologia Experimentalis et Applicata, 2006
AbstractWe compared the efficacy of four plant essential oils to repel onion thrips, Thrips tabaci (Lindeman) (Thysanoptera: Thripidae), in the presence of an attractive odour, ethyl iso‐nicotinate in a pasture field. Four horizontal white sticky plates were placed adjacent to (directions: N, S, E, W) a central horizontal white plate (C).

Genetic variation in chrysanthemum for resistance to Western Flower Thrips and Thrips tabaci

1995
In a choice experiment, resistance of 43 chrysanthemum cultivars to western flower thrips (WFT) damage was measured. Two distinct types of damage were observed, both were log-normally distributed and only a few cultivars were highly susceptible. Significant differences were found among cultivars in the amount of both types of damage.
