“…In the choice tests, a greater increase in oviposition rate into leaf tissue was observed for F. occidentalis than for F. fusca with the pollen treatment. A similar finding by Chitturi et al. (2006) suggests that there is also more adult settling on leaf tissue by F. occidentalis than by F. fusca with the same pollen treatment.…”

“…The suitability of host plants on which thrips feed significantly influences the virus acquisition and transmission by affecting ingestion rates (German et al., 1992). Also, the presence of pollen on leaf surfaces can increase the amount of time spent settling by Frankliniella species on that leaf surface (Chitturi et al., 2006). This is important because more time settling on the plant is associated with greater levels of Tospovirus transmission (Wijkamp & Peters, 1993).…”

“…Also, as annual pine pollen production cycles occur on a very large scale in the southeastern USA (Dorman & Barber, 1956), this could be an important factor in thrips population dynamics. Because the tobacco thrips, F. fusca (Hinds), is an important vector of TSWV in the southeastern USA (Chamberlin et al., 1992) and pine pollen affects its behavior (Chitturi et al., 2006), it was important to investigate the effect of pollen on F. fusca oviposition as well. Only a few studies have been conducted on the reproduction behavior of F. fusca (Lowry et al., 1992; Chaisuekul & Riley, 2005) and none with pollen.…”

Tree pollen, especially Pinus spp. (Pinaceae), is shed in large quantities every spring in North America. Pine pollen deposition onto leaves was found to significantly influence the ovipositional behaviors of certain thrips species (Thysanoptera: Thripidae) in peanut and tomato leaf choice and no‐choice tests. Pine pollen (Pinus elliottii Engelm.) increased the oviposition rate 2.9‐fold for Frankliniella occidentalis (Pergande) (western flower thrips) and 1.6‐fold for Frankliniella fusca (Hinds) (tobacco thrips) in choice tests averaged over both plant species. These results support the idea that pollen has a greater impact on F. occidentalis behavior than on F. fusca behavior. The most dramatic increase was in peanut, where F. occidentalis only oviposited on leaves dusted with pollen, suggesting that the addition of pollen stimulated this flower thrips to lay eggs on a poor host‐plant part. The impact of pollen on the rate of oviposition by thrips is important because it is the early‐instar nymphs that acquire tomato spotted wilt virus (TSWV), which these two thrips species vector. In a laboratory bioassay, the addition of pine pollen to TSWV‐infected peanut foliage increased the percentage of infected F. fusca after one generation.

“…Chitturi et al. () have shown that female F. occidentalis prefer to feed on whole plant compared with excised leaves in a choice test. However, a previous study showed high correlation between thrips injury observed in leaf bioassays and in whole plant tests (Maharijaya et al., ), which indicates that it is possible to use leaf bioassays to rate the level of resistance of pepper against thrips.…”

The western flower thrips [Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae)] is a major pest in pepper cultivation. Therefore, host plant resistance to thrips is a desirable trait. The objectives of this study were to determine the effect of resistance on the development of thrips and to identify metabolite compounds related to the resistance. Three highly resistant, three medium resistant, and three susceptible pepper accessions were used in this study. Adult and pre‐adult survival, developmental time, and oviposition rate were assessed. Gas chromatography‐mass spectrometry was used to identify compounds that correlate with the level of resistance to thrips. Our results show that resistance of pepper accessions has a significant effect on oviposition rate and larval mortality. Seven compounds were identified that correlate with resistance to thrips and six compounds were identified that correlate with susceptibility to thrips. Some of these compounds, such as tocopherols, were previously shown to have an effect on insects in general. Also, some specific secondary metabolites (alkanes) seem to be more abundant in susceptible accessions and were induced by thrips infestation.

“…Females were especially abundant in anthesis‐stage flowers, as shown by Milne and Walter (). This association of thrips with pollen is evident also in other Frankliniella species (Chitturi et al ., ). Further, adult thrips in anthesis and, especially, postanthesis flowers were mostly distributed at the apex of the flower as opposed to preanthesis flowers where most thrips were in mid and base sections (Fig.…”

Tiny insects against the weather—flight and foraging patterns of Frankliniella schultzei (Thripidae) not altered by onset of rainfall

To survive in nature, organisms may need to take direct action to mitigate specific dangers from their environmental surroundings. Tiny flying insects are thought to be at particular risk from rainfall that would be of negligible concern to larger animals. The study species Frankliniella schultzei is a thrips that inhabits flowers and feeds mostly on petal tissue and pollen. While found to respond in the laboratory to decreases in atmospheric pressure associated with cyclonic conditions (rather than merely heavy rainfall), their responses to conditions preceding rainfall have not been tested in the field. Initial field sampling investigated the relationship between floral development and sites at which male, female, and larval thrips were generally present on sunny days. We then designed a sampling strategy to test if these thrips can anticipate imminent rainfall or storms and so seek shelter deep within flowers, by sampling host flowers (in sections) on multiple days with different weather conditions. Sticky traps were used to intercept thrips in flight, thus providing a measure of flight behavior across different days. The initial sampling found adult thrips primarily at the petal apex of anthesis-stage flowers where pollen is distributed. We subsequently found that rainfall, atmospheric pressure change, temperature, humidity and wind had no effect on flight behavior of F. schultzei, or on their positions within flowers. These findings suggest rainfall is not a serious hazard for them. Perhaps thrips can survive raindrop collisions during flight, as impacts with water droplets are not expected to break the surface tension.
