“…Furthermore, the control of this thrips with those pesticides still available on the market is unsatisfactory (Brødsgaard 1994;Schade and Sengonca 1995). While synthetic pyrethroids and imidacloprid are also toxic to natural enemies (Nemoto 1995), other insecticides have limited efficacy against this pest (Robb et al 1995). For these reasons, biological control is a promising strategy for the control of this thrips (Jacobson 1997;Dekeyzer 2001).…”

In the present study, the suitability of different predatory bug species, such as Dicyphus tamaninii Wagner, Macrolophus pygmaeus (Rambur), Orius albidipennis Reuter, Orius majusculus Reuter and Orius sauteri Poppius, for the biological control of Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), were investigated. Development of the predatory bug species, their reproduction as well as their daily and total prey consumption over a 18-day period with F. occidentalis larvae or various stages of Tetranychus urticae Koch (Acari: Tetranychidae) individuals as prey species were studied during the experiments in the laboratory. In further experiments, the efficiency of D. tamaninii, M. pygmaeus, O. albidipennis and O. majusculus in controlling F. occidentalis under glasshouse conditions was investigated. Results showed that all the predators could develop under the experimental conditions with either F. occidentalis larvae or different stages of T. urticae as prey. When F. occidentalis larvae were offered as prey, the shortest duration of development was observed for O. albidipennis with a mean of 17.7 days, while D. tamaninii took the longest to develop with a mean of 36.3 days. With different stages of T. urticae as prey, the duration of development ranged from 19.3 days in O. albidipennis to 42.9 days in M. pygmaeus. Mean daily fecundity ranged from 0.8 eggs/female for O. majusculus to 2.2 eggs/female for O. sauteri with F. occidentalis larvae as prey and from 0.6, O. majusculus, to 2.3 eggs/female/day, O. sauteri, when different stages of T. urticae were offered as prey. Over the 18-day reproduction period, O. sauteri was the most fecund predatory species, laying a mean total of 31.6 and 31.3 eggs/female with F. occidentalis and T. urticae as prey, respectively. Daily consumption from F. occidentalis larvae ranged between 5.5 individuals consumed per day by O. majusculus and 29.1, by O. sauteri. When different stages of T. urticae were offered as prey, maximal consumption was observed in D. tamaninii with a mean of 29.0 individuals/day, while O. albidipennis consumed the least with an average of 8.1 preys/day. Over the 18-day prey consumption period, D. tamaninii consumed the highest mean number of 422.8 F. occidentalis larvae, while O. majusculus only consumed 98.8 larvae. Also, D. tamaninii had the maximum consumption of different stages of T. urticae with a mean of 522.4, while M. pygmaeus and O. albidipennis consumed the least, with an average of 146.1 and 146.0, respectively. The predatory bugs D. tamaninii, M. pygmaeus, O. albidipennis and O. majusculus significantly reduced the density of F. occidentalis on hybrids of Euphorbia milii, Serissa foetida and Saintpaulia ionantha in the glasshouse, which confirms their efficiency against this pest on different hosts under controlled climatic conditions.

“…For decades, the use of insecticides has been the primary strategy for controlling this insect pest. However, several F. occidentalis populations from different geographical areas have developed insecticide resistance (9,43,59). Additionally, F. occidentalis displays thigmotactic behavior, whereby the insect prefers concealed spaces on or in plant organs, protecting it from harsh conditions.…”

Tomato spotted wilt virus(TSWV) is transmitted byFrankliniella occidentalisin a persistent propagative manner. Despite the extensive replication of TSWV in midgut and salivary glands, there is little to no pathogenic effect onF. occidentalis. We hypothesize that the first-instar larva (L1) ofF. occidentalismounts a response to TSWV that protects it from pathogenic effects caused by virus infection and replication in various insect tissues. A partial thrips transcriptome was generated using 454-Titanium sequencing of cDNA generated fromF. occidentalisexposed to TSWV. Using these sequences, the L1 thrips proteome that resolved on a two-dimensional gel was characterized. Forty-seven percent of the resolved protein spots were identified using the thrips transcriptome. Real-time quantitative reverse transcriptase PCR (RT-PCR) analysis of virus titer in L1 thrips revealed a significant increase in the normalized abundance of TSWV nucleocapsid RNA from 2 to 21 h after a 3-h acquisition access period on virus-infected plant tissue, indicative of infection and accumulation of virus. We compared the proteomes of infected and noninfected L1s to identify proteins that display differential abundances in response to virus. Using four biological replicates, 26 spots containing 37 proteins were significantly altered in response to TSWV. Gene ontology assignments for 32 of these proteins revealed biological roles associated with the infection cycle of other plant- and animal-infecting viruses and antiviral defense responses. Our findings support the hypothesis that L1 thrips display a complex reaction to TSWV infection and provide new insights toward unraveling the molecular basis of this interaction.

“…De acordo com VAN DRIESCHE et al (1998), os sintomas de alimentação de tripes não são notados até que sérios danos tenham ocorrido. Além disso, seu controle é dificultado principalmente devido ao tamanho reduzido, rápida reprodução e preferência alimentar pela parte interna de flores e de brotos, além da resistência a vários inseticidas (IMMARAJU et al, 1992;ROBB et al, 1995). Os pulgões causam prejuízos devido à sucção da seiva, secreção de "honeydew", deposição de substâncias tóxicas, deformação de brotos e botões florais (BERGMAN et al, 1996).…”

RESUMOOs pulgões e os tripes são importantes pragas em cultivo de crisântemo em casas de vegetação. O objetivo deste trabalho foi avaliar a ocorrência e flutuação populacional de tripes, pulgões e inimigos naturais em cultivares de crisântemo de corte ('White Reagan', 'Yellow Snowdon' e 'Sunny Reagan') em casa de vegetação comercial. A amostragem de tripes foi realizada através de batidas nas plantas ("tapping method") e a de pulgões a partir de coletas diretas nas plantas. Das espécies de tripes amostradas, mais de 90% foram identificadas como Frankliniella occidentalis (Pergande), e o restante incluíram F. gemina (Bagnall), Frankliniella sp., Caliothrips phaseoli (Hood) e Haplothrips gowdeyi (Franklin). Foi observado maior número de tripes/planta no cultivar White Reagan se comparado com 'Yellow Snowdon'. Aphis gossypii Glover foi a espécie de pulgão mais comum (> 80%), sendo também coletados Myzus persicae (Sulzer) e Dysaphis sp. Maior número de pulgões foi verificado na cultivar White Reagan, quando comparada com 'Sunny Reagan'. Orius insidiosus (Say) foi o único predador encontrado associado aos tripes, sendo verificada uma correlação positiva significativa entre a população de tripes e a desse predador. Dentre os inimigos naturais relacionados aos pulgões, foram observados parasitóides (Aphidius colemani Viereck e Lysiphlebus testaceipes Cresson) e predadores (Chrysoperla sp., Cycloneda sanguinea Linnaeus e Scymnus sp.). Houve uma correlação positiva significativa entre o crescimento populacional de pulgões e desses predadores e parasitóides nas cultivares White Reagan e Sunny Reagan. Inimigos naturais podem ocorrer naturalmente em casas de vegetação e influenciar as populações de pragas. Palavras-chave:Dendrathema grandiflora, insetos-praga, predadores, parasitóides. ABSTRACT OCCURRENCE AND POPULATION FLUCTUATION OF THRIPS, APHIDS AND NATURAL ENEMIES IN CUT CHRYSANTHEMUM IN GREENHOUSEAphids and thrips play an important role on chrysanthemum crops in greenhouses. The objective of this work was to evaluate the occurrence and population densities of thrips, aphids and natural enemies in cut chrysanthemum cultivars ('White Reagan', 'Yellow Snowdon' and 'Sunny Reagan') in commercial greenhouse. Thrips sampling was made by the tapping method, while aphids were sampled by direct counting on the plants. Frankliniella occidentalis (Pergande) (>90%), F. gemina, Frankliniella sp., Caliothrips phaseoli (Hood) and Haplothrips gowdeyi (Franklin) were the thrips species found. A higher number of thrips/plant was found in 'White Reagan' compared with 'Yellow Snowdon' cultivar. The aphid species Aphis gossypii (Glover) (>80%), Myzus persicae (Sulzer) and Dysaphis sp. were found. A higher number of aphids were found in 'White Reagan' than in 'Sunny Reagan' cultivar. The predatory bug Orius insidiosus (Say) was the only species found associated with thrips in all chrysanthemum cultivars. A positive correlation between thrips and O. insidiosus populations was found. Among the natural enemies associated
