“…Psyllid is a kind of sucking insect highly dependent on its host [11][12][13][14][15][16][17]. Many gall inducers in Psylloidea are highly host-specific and occur in all of the currently recognized families [46][47][48][49].…”

“…These flower-like galls on H. persicum and H. ammodendron were associated with various pests that mainly belong to Psyllidae, Pyralidae, Pseudococcidae, and Thripidae. Moreover, psyllids are globally known as the major gall inducers on various organs of cultivated plants and forest trees, which are highly dependent on their host [11][12][13][14][15][16][17]. They have been recorded from the galls on Haloxylon frequently.…”

Saxaul is a kind of dominant perennial psammophyte that widely distributes in arid and semi-arid desert areas, and it has multiple functions in preventing desertification, especially in windbreak and sand fixation. Various gall inducers induce galls on the saxaul, including the flower-like gall. Parasitoids have great potentiality in controlling gall inducers. However, studies about gall inducers and parasitoids of flower-like galls on Haloxylon, as well as the parasitic efficacy of the parasitoids, are rarely reported. In this study, the flower-like galls were observed on Haloxylon ammodendron and H. persicum in Fukang, Xinjiang, China. Two types of flower-like galls were found on H. ammodendron, while only one type was found on H. persicum. In total, five species of gall inducers and three species of parasitoids were obtained from the galls mentioned above. All the galls were induced by Caillardia (Hemiptera: Aphalaridae), which were mostly bivoltine in Fukang. Besides, their parasitoids Psyllaephagus caillardiae and P. longiventris could be observed on all the types of galls. Additionally, correlative studies on the parasitization indexes demonstrated that all the dominant parasitoids of diverse flower-like galls were P. caillardiae, which were slightly more in number than the P. ogazae discovered in the flower bud-like galls. In addition, the relevance between the emergence or lifespan of parasitoids and temperature was also investigated. The results showed that the number of parasitoids emerging decreased rapidly after a period of enhancement with the increase of temperature, including an optimum temperature, while the lifespan of wasps gradually shortened with the temperature rising. Our results highlight the importance of the biological investigation of parasitoids in the gall inducers lived in closed galls, which may provide critical evidence for us to understand its potential application in biological control.

“…These insects represent the main obstacles to cultivate guava because they reduce the yield and quality of fruits (Yana et al, 2010;Ndankeu et al, 2011). The species Triozoida limbata Enderlein, 1918 (Hemiptera: Triozidae) is considered as one of the leading crop pests in Brazil (Colombi & Galli, 2009).…”

“…As they suck the sap at the edges of the leaves, they inject toxins (Munyaneza et al, 2010), making leaves curl and become dry, and causing the appearance of necrosis (Dalberto et al, 2004;Yana et al, 2010;Ndankeu et al, 2011).…”

Triozoida limbata is considered one of the leading pests of guava crop in Brazil. Its nymphs are responsible for sucking leaf borders, causing curling and drying of the leaves, and leaving them with a necrotic appearance. Knowledge of the spatial distribution of nymphs of T. limbata is essential for improving sampling and control techniques. The objective of this study was to perform probabilistic analyses of patterns of spatial distribution of nymphs of T. limbata in guava orchards. The study was conducted in four guava orchards in Ivinhema, Mato Grosso do Sul, Brazil. Samplings were performed every 15 days, from April 2012 to March 2014. To obtain the nymph counts, a sampling area was demarcated in each orchard, comprising 50 sampling units. In each unit, a sample was taken randomly from a shoot of 10 cm to 15 cm in length at the median height of the central plant. Dispersion rates were calculated (variance/mean ratio, Morisita index, and Exponent k of Negative Binomial Distribution) and the data obtained in the field were adjusted to the theoretical frequency distributions (Poisson and Negative Binomial). Following the analyses, we concluded that nymphs of T. limbata in the studied populations were randomly organized in the four areas that were evaluated, and the sampling data have been adjusted to the Poisson distribution model.

“…One such insect is Triozoida limbata Enderlein, 1918 (Hemiptera: Triozidae), which is currently considered as one of the main guava crop pests in Brazil (Colombi & Galli, 2009). During the development of the plant, the young leaves are attacked by this insect (Sá, 2011), which sucks the sap from leaf edges and injects toxins in them (Munyaneza et al, 2010), causing the leaves to curl and wither, giving them the appearance of necrosis and limiting the production and quality of the fruits (Yana et al, 2010;Ndankeu et al, 2011).…”

The aim of this study was to carry out probabilistic analyses of the spatial distribution patterns of adults of Triozoida limbata Enderlein, 1918 (Hemiptera: Triozidae) in guava orchards. This study was conducted in four guava orchards in Ivinhema, Mato Grosso do Sul, Brazil. The samplings were conducted every fortnight from April 2012 to March 2014. A sampling area was set up for adult samples, and it consisted of 24 sampling units or plots with 15 plants in each (3 rows × 5 plants). A double-sided adhesive yellow trap was installed, 23 cm in length and 11 cm in width, around the central plant of each sampling unit, approximately 1.5 m from the ground. The dispersion rates (variance/mean ratio, Morisita index and Exponent k of the Negative Binomial Distribution) and the theoretical frequency distributions (Poisson and Negative Binomial) were calculated. Following the analyses, it can be concluded that the adults of T. limbata of the populations studied are randomly distributed in the four areas evaluated, with the sampling data fitting the Poisson distribution model.
