The Life Table Parameters of Megalurothrips Usitatus
The life table parameters of Megalurothrips usitatus (Thysanoptera: Thripidae) on four leguminous crops Liang-De Tang1, Kai-Li Yan1, Bu-Li Fu1, Jian-Hui Wu2, Kui Liu1,*, and Yong-Yue Lu1,2,* Abstract The bean flower thrips, Megalurothrips usitatus (Thysanoptera: Thripidae), is an important pest of leguminous crops (Fabales: Fabaceae) in south China. In this study, life history parameters of M. usitatus were investigated on 4 leguminous crops: snap bean (Phaseolus vulgaris L.), cowpea (Vigna unguiculata (L.) Walp.), pea (Pisum sativum L.), and lima bean (Phaseolus limensis Macf.). The development times (mean ± SE) from egg to adult on snap bean, cowpea, pea, and lima bean pods were 9.53 ± 0.06, 10.62 ± 0.14, 11.20 ± 0.11 and 11.55 ± 1.13 days, respectively. Survivorship of immatures was high on snap bean (80%) but low on lima bean (48%). The total number of first instars produced was highest on snap bean (sexual reproduction: 112.15 ± 11.98; parthenogenesis: 195.89 ± 19.24), and lowest on lima bean (sexual reproduction: 42.17 ± 2.99; parthenogenesis: 49.50 ± 3.90). Megalurothrips usitatus had the highest intrinsic rate of increase (rm) on snap bean (0.205), followed by cowpea (0.181), pea (0.171), and lima bean (0.125). The results indicate that snap bean was the most suitable host plant for M. usitatus, whereas lima bean was the least suitable. Key Words: Megalurothrips usitatus; life history; leguminous crops; development; survival rate Resumen Los trips de las flores de frijol,Megalurothrips usitatus (Thysanoptera: Thripidae), son una plaga importante de cultivos leguminosos (Fabales: Fabaceae) en el sur de China. -

Walp. To understand the mechanism underpinning this behavior, we studied the responses of M. sjostedti to headspace volatiles from conspecifics in a four-arm olfactometer. Both male and female M. sjostedti were attracted to male, but not to female odor. Gas chromatography/mass spectrometry (GC/ MS) analyses revealed the presence of two distinct compounds in male M. sjostedti headspace, namely (R)-lavandulyl 3-methylbutanoate (major compound) and (R)-lavandulol (minor compound); by contrast, both compounds were only present in trace amounts in female headspace collections. A behavioral assay using synthetic compounds showed that male M. sjostedti was attracted to both (R)-lavandulyl 3-methylbutanoate and (R)-lavandulol, while females responded only to (R)-lavandulyl 3-methylbutanoate. This is the first report of a male-produced aggregation pheromone in the genus Megalurothrips. The bean flower thrips is the primary pest of cowpea, which is widely grown in sub-Saharan Africa. -

ZooKeys 317: 27–52. doi: 10.3897/zookeys.317.5447 Abstract An illustrated key is provided for the identification of 35 genera of Thripinae (Thysanoptera: Thripidae) from Iran with comments for each genus. Chirothrips maximi Ananthakrishnan and Limothrips cerealium Haliday are recorded from Iran for the first time. A checklist is provided of Thripinae recorded from this country. Keywords Thysanoptera, Thripinae, identification, Iran Introduction The family Thripidae (Thysanoptera: Terebrantia) at present comprises more than 2000 described species, which are classified into four subfamilies, Thripinae, Dendro- thripinae, Sericothripinae, and Panchaetothripinae (Bhatti 1989). The present study follows the interpretation of Thripinae in this classification. Another recent classifica- tion of Terebrantia (Bhatti 2006) recognizes three superfamilies and 12 families for taxa included in the four subfamilies of Thripidae, and the taxa of the earlier subfam- ily Thripinae are included in three families (Chirothripidae, Projectothripidae, and Thripidae) (Bhatti 2006). -
Phylogenetic Analysis of the Taeniothrips Genus-Group, with Revision of the Species of Ctenothrips and Vulgatothrips (Thysanoptera, Thripinae)

[e-mail: [email protected]] 3Plant Protection College, Yunnan Agricultural University, Kunming, 650201, P.R. China Abstract The pattern of relationships within the Taeniothrips genus-group was examined using a morphological phylogenetic analysis. Genera comprising this group are discussed together with some character states used in the analysis. Taeniothrips genus-group is recovered as monophyletic, but Taeniothrips appears to be polyphyletic. Ctenothrips is here interpreted as sister-group to Vulgatothrips, with Ctenothrips smilax and C. dissimilis transferred to Vulgatothrips, and C. niger synonymized with C. smilax. Diagnoses of Ctenothrips and Vulgatothrips are presented with illustrated keys to distinguish these genera and their included species, and eight species are newly synonymised in Ctenothrips. Key words: cladistic analysis, keys, new synonyms, new combinations, new species Introduction The suprageneric classification within the Thysanoptera subfamily Thripinae is far from satisfactory, with a very high proportion of the 230 listed genera monobasic. In an attempt to develop some phylogenetic structure within the subfamily, Mound and Palmer (1981) proposed six genus-groups. -
Nematoda: Tylenchida: Allantonematidae)1 Danielle Sprague and Joe Funderburk2
EENY681 Entomopathogenic Nematodes of Thrips Thripinema spp. (Nematoda: Tylenchida: Allantonematidae)1 Danielle Sprague and Joe Funderburk2 Introduction Several species of entomopathogenic nematodes in the genus Thripinema are known to naturally parasitize thrips (Thysanoptera). Thripinema fuscum Tipping and Nguyen is the most common species in Florida (Figure 1). Thripinema fuscum is economically important because it is a natural enemy of the insect pest, the tobacco thrips, Frankliniella fusca (Hinds). Taxonomy The first observation of parasitic nematodes of thrips was made by Uzel (1895) in Europe when an unnamed nema- tode was reported in the body cavity of Thrips physapus L. A nematode inhabiting bean thrips, Heliothrips fasciatus L., was reported in California by Russell (1912), but not described. The first description of parasitic nematodes of thrips was not made until 1932 by Sharga, who described the Figure 1. Thripinema fuscum, female. A) Infective female. B) Anterior nematode Tylenchus aptini from Aptinothrips rufus Gmelin region of infective female. C, D, F) Progressive enlargement of parasitic in England.

A. MOUND1, A. A. AZIDAH2 & Y. F. NG3 1Honorary Research Fellow, CSIRO Ecosystem Sciences, Canberra, ACT 2601, Australia. E-mail: [email protected] 2Institute of Biological Sciences, University of Malaya, Kuala Lumpur, Malaysia. E-mail: [email protected] 3Centre for Insect Systematics (CIS), Universiti Kebangsaan Malaysia, 43600 Bangi, Selangor, Malaysia. E-mail: [email protected] Abstract A table is provided of the 24 non-fossil species currently listed in Taeniothrips. One species, pediculae, is clearly not a member of this genus, dealatus and sexnotatus remain nomina dubia, and angustiglandus is unrecognisable having been based on males only. A key is provided to the remaining 20 species of the genus, including Taeniothrips damansarae sp.n. from Malaysia that has unique setal apices. Many of these 20 species involve recognition problems that are discussed based largely on type material. Key words: Taeniothrips, species identification, Southeast Asia, new species Introduction Taeniothrips is one of the oldest generic names in the Thysanoptera. Linnaeus and his contemporaries recognised only the single genus Thrips, but Haliday (1836) added 10 genera, and Amyot & Serville (1843) a further five genera including Taeniothrips. Over the succeeding century and a half, Taeniothrips was interpreted in many different ways. Even throughout much of the 1960’s and 1970’s authors continued to use this genus in a non- phylogenetic sense. For example, Mound (1966) included in Taeniothrips several species from Britain that are now placed in four different genera - Ceratothrips, Mycterothrips, Tenothrips, or Thrips, and Schliephake & Klimt (1979) treated the German fauna in a similar way.
