To Stephanitis Takeyai (Hemiptera: Tingidae)
PLANT-INSECT INTERACTIONS Resistance Mechanisms in Pieris Taxa (Ericaceae) to Stephanitis takeyai (Hemiptera: Tingidae) 1,2 1 3 SHAKUNTHALA NAIR, S. KRISTINE BRAMAN, AND D. A. KNAUFT Environ. Entomol. 41(5): 1153Ð1162 (2012); DOI: http://dx.doi.org/10.1603/EN11323 ABSTRACT This study examines some of the potential mechanisms of resistance in selected Pieris (Ericaceae) taxa to the Andromeda lace bug, Stephanitis takeyai Drake and Maa, based on differences in resistance to lace bug feeding, and the possible role of leaf parameters such as leaf wax, toughness, nutrient composition, and stomatal characters in plant resistance. Experiments with extracts of leaf-surface lipids revealed that Pieris leaf wax did not have a role in resistance to lace bug feeding. Leaf wax extracts from a resistant species P. phillyreifolia (Hook.) DC. applied to leaves of a susceptible cultivar P. japonica (Thunb.) D.Don ex G.Don ÔTemple BellsÕ did not affect feeding, oviposition, or survival of S. takeyai; and neither the extracts from Temple Bells induce susceptibility in P. philly- reifolia. Leaf penetrometer measurements indicated that signiÞcantly higher force was required to puncture P. phillyreifolia leaves, which also had higher Þber, lignin, and cellulose, and lower leaf moisture contents. Ultrastructural examination of leaves of Pieris taxa revealed signiÞcant differences in the number and size of stomata. P. phillyreifolia leaves had the highest number of stomata per unit area but these were the smallest in size, whereas P. japonica (Thunb.) D.Don ex G.Don Temple Bells leaves had the fewest and largest stomata. Resistance in Pieris taxa to S. takeyai may be attributed to a combination of different factors including leaf toughness, moisture, and stomatal characters. -

EENY-133 Lesser Canna Leafroller, Geshna cannalis (Quaintance) (Insecta: Lepidoptera: Pyralidae)1 Heather J. McAuslane2 Introduction Description and Life History The lesser canna leafroller, Geshna cannalis Adult G. cannalis are nondescript, small, (Quaintance), can be a serious pest of ornamental light-brown pyralid moths which may be found canna, Canna spp., in Florida. It is one of two resting in the shade of a canna plant during the day. leaf-rolling lepidopteran species found infesting The female wing span averages 25 mm (Quaintance canna, the other one being the larger and more 1898). There are two brownish black lines across the voracious larger canna leafroller, Calpodes ethlius fore- and hindwings, and a small angular white patch (Stoll). Cannas may be infested with both species near the distal portion of the discal cell of the simultaneously. forewing. Females lay eggs in groups of six to 15 on the upper surface of a canna leaf (Quaintance 1898). Distribution Eggs are flat, clear whitish yellow in color, and average 0.9 mm in size. Very little is known about the distribution of G. cannalis but it appears to be distributed throughout The first instars hatch and feed as leaf miners, the southeastern United States. It has been recorded tunneling between the upper and lower epidermis and as a pest of canna in Florida (Kimball 1965), excreting much frass into the tunnel. This first larval Mississippi, and North Carolina (see North Carolina instar measures 1.4 mm in length and has a yellowish, Pest News). -
Revision of the Genus Tithonia •. • •
.;. .• • • REVISION OF THE GENUS TITHONIA •. • • By S. F. BLAKE. INTRODUCTION. The genus Tith01lia, originally described in 1789 in Jussieu's Genera 1 without citation of species, was adopted by J. F. Gmelin' two years later, and the single known species was given the binomial T. unijWra, a name which has been universally displaced by the later Tithooia tagetijlqra, published by Desfontaines in 1802 with a full description and plate. The same plant, grown by Philip Mi lIer in his Chelsea garden from seed sent presumably from Veracruz by William Houstoun, had been described in the eighth edition of the Gardeners' Dictionary in 1768 as Tagetes rotundifolia, and as this is the earliest binomial given the species it must now be known as Tithonia rOflundifolia. It is a showy annual with large, orange or golden-yellow heads, much like the common sunflower in appearance except for the yellow disk, and seems worthy the attention of horticulturists. As here recognized, the genus Tithooia includes ten species, native from northern Mexico to Panama. One species, T. rotundifolia, occurs also in the Greater and Lesser Antilles, and in Venezuela (where certainly introduced), and another, T. diversifolia, has become a weed in Ceylon and Burma and at Singapore. As the relationships of the genus to Helianthus and Viguiera have already been COn sidered in some detail by the writer in another publication,' only brief notice of them is necessary here. The typical pappus-bearing members of the genus are separated from H elianthU8 by their per sistent pappus of awns and squamellae, and from Viguiera chiefly by their fistulose peduncles and by certain details of involucre. -

Barbara van Asch - [email protected] ABSTRACT Olive lace bugs are small phytophagous Hemipteran insects known to cause agricultural losses in olive production in South Africa. Plerochila australis (Distant, 1904) has been reported as the species responsible for damage to olive trees; however, the diversity of olive lace bug species in the region has lacked attention. Adult olive lace bugs were collected incidentally from wild and cultivated olive trees in the Western Cape Province, and identified as P. australis and Neoplerochila paliatseasi (Rodrigues, 1981). -

ECOLOGICAL FACTORS AFFECTING THE ESTABLISHMENT OF THE BIOLOGICAL CONTROL AGENT Gargaphia decoris DRAKE (HEMIPTERA: TINGIDAE) A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Plant Science at Massey University, Manawatu, New Zealand Cecilia María Falla 2017 ABSTRACT The Brazilian lace bug (Gargaphia decoris Drake (Hemiptera:Tingidae)) was released in New Zealand in 2010 for the biological control of the invasive weed woolly nightshade (Solanum mauritianum Scopoli (Solanaceae)). Currently there is scarce information about the potential effect of ecological factors on the establishment of this biological control agent. This study investigated: 1) the effect of maternal care and aggregation on nymphal survival and development; 2) the effect of temperature, photoperiod and humidity on G. decoris performance; and 3) the effect of light intensity on S. mauritianum and G. decoris performance. Maternal care and aggregation are characteristic behaviours of G. decoris. These behaviours have an adaptive significance for the offspring and are key determinants for the survival of the species under natural conditions. Maternal care is reported to increase the survival and development of offspring under field conditions, and higher aggregations to increase the survival of the offspring. However, in this study, maternal care negatively affected the survival and development of the offspring, and higher aggregations had no significant impact on offspring survival.
