Abstract Studies were conducted from 2015 to 2018 to evaluate spotted lanternfly (SLF) distribution and developmental suitability of different plant species in the U.S. Tree bands on 283 trees spanning 33 species captured 21,006 SLF in 2 yr. More SLF per tree were trapped on tree-of-heaven Ailanthus altissima (Mill.) Swingle (Sapindales: Simaroubaceae) than on other species, on average, and most adults were captured on tree-of-heaven. Frequency of detection of adult SLF was higher on tree-of-heaven than on other species but was actually equal or lower on tree-of-heaven than on all other species combined for younger SLF stages in 2015. An enclosed choice test between tree-of-heaven and black walnut Juglans nigra L. (Fagales: Juglandaceae) revealed nymphs showed little consistent preference, whereas adults consistently and significantly preferred tree-of-heaven. No-choice field sleeve studies evaluated SLF survivorship on 26 host plant species in 17 families. Ten plant species supported SLF for an average of ≥45 d, with the rest unable to support SLF for >30 d. Eight species were able to support development from first instar to adult: black walnut, chinaberry Melia azedarach L. (Sapindales: Meliaceae), oriental bittersweet Celastrus orbiculatus Thunb. (Celastrales: Celastraceae), tree-of-heaven, hops Humulus lupulus L. (Rosales: Cannabaceae), sawtooth oak Quercus acutissima Carruthers (Fagales: Fagaceae), butternut Juglans cinerea L, and tulip tree Liriodendron tulipifiera L. (Magnoliales: Magnoliaceae). The ability of SLF to develop to adult on hosts other than tree-of-heaven may impact pest management decisions.

The stem borer Busseola fusca (Fuller) (Lepidoptera: Noctuidae) is an important pest of maize and sorghum in sub-Saharan Africa. This insect has oligophagous feeding habits, feeding mostly on maize and sorghum with a narrow range of wild Poaceous plant species. We hypothesised that first instar B. fusca larvae, the critical stage for successful establishment on a host plant, can establish and then grow on a particular plant as a result of induction of a complement of digestive enzymes that mediates host acceptance at first instars. A fast semi-quantitative analysis of potentially digestive enzymatic activities present in the first larvae previously fed for 4 days on leaves of host and non-host plants was performed using the API-ZYM kit system able to detect a multiplex of enzyme activities. Regardless of the plant species, the larvae exhibited higher activities of the carbohydrate metabolising enzymes than of aminopeptidases and proteases. In addition, highest activities of carbohydrates degrading enzymes were exhibited by larvae that consumed leaves of the most preferred plant species of B. fusca. Conversely, esterases were only detected in neonate larvae that consumed leaves of the less preferred and non-host plants. No alkaline phosphatase and lipase activities were detected. The significance of these results was discussed in terms of food requirements of first instar larvae when settling on a plant.

Activity of Melia azedarach (L.) seed extract against armyworm Spodoptera litura (F.) (Lepidoptera: Noctuidae). This study was conducted to evaluate the effectivenes and biological activity of Melia azedarach L. (Meliaceae) seed extract against armyworm, Spodoptera litura F. The first instar larvae were fed extract-treated cotton leaves for 2 days, then were maintained on untreated leaves until the third instar stage. Records were kept in regard to the larvae mortality and developmental time of surviving larvae from first instar to third instar. The result showed that Melia azedarach L. seed extract at consentration of 50 g of seeds/l of water (5%) exhibited moderate insecticidal activity against S. litura larvae (43.33 - 68.33% mortality). Addition of detergen at 0.2% to extract did not increase insecticidal activity of the extract. However, boiling seed extract at consentration of 50 g of seeds/l of water (5%) during 10 until 20 minutes increased insecticidal activity of extract (66.67 - 68.33% mortality). Generally, M. azedarach seed extract treatment did not affect  developmental time of  S. litura larvae.

AbstractThe wheat midge, Sitodiplosis mosellana (Géhin), infests wheat, Triticum aestivum L., heads only up to anthesis when pollination occurs. The termination of infestation might be due to a deterrence of oviposition or to a suppression of larval growth on developing seeds. These hypotheses were tested in the laboratory by measuring oviposition preference, larval development, and larval preference for plants at different growth stages. Females showed no preference for ovipositing on heads at any stage from the onset of heading up to and including anthesis, and continued to lay eggs at a reduced rate 10 days after anthesis. Survival of newly hatched larvae was reduced on seeds 3–1 days after anthesis and survival and development was greatly reduced on seeds 5 or 6 days after anthesis. Larvae moved away from older seeds and fed on younger seeds in a choice test. Given a hatching time of 5–6 days, a failure to infest wheat after anthesis is not due to oviposition deterrence at anthesis, but to suppression of larval growth and development which begins soon after anthesis.

Survival And Development

First instar nymphs of Monellia caryella (Fitch), Monelliopsis pecanis Bissell, and Melanocallis caryaefoliae (Davis), were exposed to temperatures of 25, 30, 35, and 40° C for up to 9 days. Test aphids were observed for growth, maturity, natality and mortality at each temperature. For three species mortality was low at 25° C but development was slowed; at 30° C mortality increased slightly but development and natality was optimum; at 35° C mortality was greatly increased and maturity was not attained; at 40° C first instar aphids did not survive beyond one day. In further testing with hourly observations at 40° C, M. caryella had 100% mortality after 6 h-exposure, M. pecanis had 100% mortality after 9 h, and M. caryaefoliae survived for 11 h and was the most tolerant of 40° C.

Phylogenetic Lineages

Genus- and species-level differences characterize the pattern of life-history variation in two distinct phylogenetic lineages of chrysopids, Chrysopa and Chrysoperla. Species in the genus Chrysopa exhibit significant variation in egg size, and this variation is positively correlated with the ability of hatchlings to withstand periods of food and water deprivation prior to their initial feeding. The variation is also significantly correlated with larval size, as measured by the tibial length of first-instar larvae. Although the six Chrysopa species differ in several other life-history traits (i.e, the incubation period and rate of first-instar larval development), the variation is unrelated to egg size. It appears that maternal allocation of resources to eggs largely serves to enhance embryonic growth and the survival of hatchlings during searching. That is, within the Chrysopa lineage egg size varies; larger eggs yield larger, more robust hatchlings. These hatchlings may or may not develop faster than congeners from small eggs. In comparison with Chrysopa, the genus Chrysoperla has less variability in egg size and developmental rate. Furthermore, although Chrysoperla eggs are relatively small, the ability of hatchlings to endure periods of food or water deprivation is at least as great as it is in the Chrysopa species with large eggs. We conclude that maternal investment in larval fitness has different ontogenetic pathways, ecological roles, and phylogenetic histories in the two genera.

Abstract Twenty-six species and/or cultivars commonly used in landscapes of the southeastern United States were exposed to three ozone (O3) levels for 3-week periods during spring and summer 1994. Thirteen species or cultivars exhibited visible foliar injury at the highest rate, 2.5× ambient, and two cultivars exhibited foliar injury with ambient O3 concentrations. The most sensitive were two cultivars of buddleia or butterfly bush (Buddleia davidii Franch. ‘Black Knight’ and ‘Royal Red’), with visible injury under ambient and 2.5× ambient O3 levels, and ‘White Star’ zinnia (Zinnia angustifolia HBK ‘White Star’) with visible injury observed under 2.5× ambient O3 levels. Seven other cultivars of buddleia and three cultivars of red maple (Acer rubrum L. ‘Autumn Flame’, ‘October Glory’, and ‘Franksred’ (Red SunsetTM)) exhibited minor foliar injury under 2.5× ambient O3 levels. Visible injury was not present on flowering dogwood (Cornus florida L. ‘Stokes Pink’), hollies (Ilex crenata Thunb. ‘Green Luster’, I. cornuta Lindl. & Paxt. ‘Carissa’, I. x attenuate Ashe ‘Fosteri #2’), cultivars of crapemyrtle (Lagerstroemia indica L. ‘Byers Wonderful White’ and ‘Carolina Beauty’), glossy abelia (Abelia x grandiflora (Andre) Rehd.), southern waxmyrtle (Myrica cerifera L.), sawtooth oak (Quercus acutissima Carruth), begonia (Begonia semperflorens-cultorum Hort. ‘Pizzazz Red’), petunia (Petunia x hybrida Hort. Vilm.-Andr. ‘Celebrity Red’), salvia (Salvia splendens Sello. ‘Hotline’), or gomphrena (Gomphrena globosa L. ‘Strawberry Fields’).

Abstract The Indian Crested Porcupine (Hystrix indica) is classified as an agricultural pest species. It feeds on plants and crops; hence, it is responsible for massive financial losses worldwide. The current study was conducted to assess the diet composition of Indian Crested Porcupine in District Bagh, Azad Jammu and Kashmir (AJ&K). Thus, fecal samples were collected and examined from different sampling sites. Reference slides of the material collected from the study area were prepared for identification of dietary components in fecal pellets. A total of 80 fecal samples were collected and processed. Percent relative frequencies (P.R.F.) were calculated for each plant species recovered from pellets. Data revealed that Indian Crested Porcupine consumed 31 plant species in its diet, among them Zea mays (34.31±7.76) was the most frequently selected species followed by Rumex obtusifolius (15.32±2.57) and Melia azedarach (12.83±4.79). The study revealed that the greatest diversity of (n=20) plant species were consumed in summer season while minimum (n=13) species were used during winter. Among the parts of plants, stem was highly consumed in spring (57.2%) as compared to seed in fall (36.7%) while spikes and leaf were the least recovered parts from the fecal matter. The Berger-Parker diversity index showed highly diversified food (10.92) in the summer time of the year as compared to the autumn season (2.95). This study provides a baseline for the diet preference of this pest in the study area. Based on current findings, a detailed investigation on damage assessment, exploration, habitat use and management of Indian Crested Porcupine in AJ&K has been recommended.

Abstract Background: Overexpression of GA20 oxidase gene has been a recent trend for improving plant growth and biomass. Constitutive expression of GA20ox has successfully improved plant growth and biomass in several plant species. However, the constitutive expression of this gene causes side-effects, such as reduced leaf size and stem diameters, etc. To avoid these effects, different tissue-specific promoters had been identified and employed for GA20ox overexpression. In this study, we demonstrate the potential of At1g, a root-preferential promoter, for GA20ox expression to enhance plant biomass in tobacco and Melia azedarach.Results: We examined the utility of At1g promoter to drive the expression of GUS (β-1,4-glucuronidase) reporter and GA20ox genes in tobacco and Melia azedarach. Histochemical GUS assays in tobacco showed that At1g was a root-preferential promoter whose expression was particularly strong in root tips. The ectopic expression of AtGA20ox gene under the control of At1g promoter showed the improved plant growth and biomass of both tobacco and M. azedarach transgenic plants compared to wild-type (WT) control plants. Stem length as well as stem and root fresh weights increased by up to 1.5-3 folds in transgenic tobacco and 2 folds in transgenic M. azedarach. Both tobacco and M. azedarach transgenic plants showed increases in the root xylem width, xylem over phloem ratio by 50%-100% as compared to WT plants. Importantly, no significant difference in the leaf shape and size was observed between At1g::AtGA20ox transgenic and WT plants. Moreover, transgenic M. azedarach showed a 135% increase in stem diameter even though no change was found in transgenic tobacco.Conclusions: These results demonstrate the great utility of At1g promoter, when driving AtGA20ox gene, for growth and biomass improvements in woody plants and potentially some other plant species.

Pl@ntNet is an international initiative which was the first one attempting to combine the force of citizens networks with automated identification tools based on machine learning technologies (Joly et al. 2014). Launched in 2009 by a consortium involving research institutes in computer sciences, ecology and agriculture, it was the starting point of several scientific and technological productions (Goëau et al. 2012) which finally led to the first release of the Pl@ntNet app (iOS in February 2013 (Goëau et al. 2013) and Android (Goëau et al. 2014) the following year). Initially based on 800 plant species, the app was progressively enlarged to thousands of species of the European, North American and tropical regions. Nowadays, the app covers more than 15 000 species and is adapted to 22 regional and thematic contexts, such as the Andean plant species, the wild salads of southern Europe, the indigenous trees species of South Africa, the flora of the Indian Ocean Islands, the New Caledonian Flora, etc. The app is translated in 11 languages and is being used by more than 3 millions of end-users all over the world, mostly in Europe and the US. The analysis of the data collected by Pl@ntnet users, which represent more than 24 millions of observations up to now, has a high potential for different ecological and management questions. A recent work (Botella et al. 2018), in particular, did show that the stream of Pl@ntNet observations could allow a fine-grained and regular monitoring of some species of interest such as invasive ones. However, this requires cautious considerations about the contexts in which the application is used. In this talk, we will synthesize the results of this study and present another one related to phenology. Indeed, as the phenological stage of the observed plants is also recorded, these data offer a rich and unique material for phenological studies at large geographical or taxonomical scale. We will share preliminary results obtained on some important pantropical species (such as the Melia azedarach L., and the Lantana camara L.), for which we have detected significant intercontinental phenological patterns, among the project data.
