Abstract Agriculture is one of the major farming activities, representing 32% of the gross domestic product of Madagascar and 74.3% of the population is involved in this activity. Fruit flies of the Tephritidae family are considered as the most destructive pests for agriculture in the country, nevertheless, few data exist on host plants and distribution of those pests. In the present study, we address those questions by conducting a large survey between November 2016 and July 2018 across the six agroecological regions of Madagascar. Fruit and vegetable were sampled from 198 plant species (wild and cultivated) and represented 37,965 fruits from all regions of Madagascar. The infestation index ranged from 0.06 to 538.46 pupae/kg, the infestation percentage was up to 54.84% in some samples, 63 plant species were considered as host of Tephritidae. Twelve fruit fly species were identified, seven of which were previously described as endemic, five species could be considered as widespread (altitudinal gradients between 1 and 1634 m asl) and major pests in Madagascar: Ceratitis malgassa (23 plant species from 12 families), Neoceratitis cyanescens (16 plant species from one family), Bactrocera dorsalis (18 plant species from 12 families), Dacus demmerezi (ten plant species from one family), Dacus vertebratus (six species from one family). Those results are of importance for implementation of control measures.

Along the Montenegrin seacoast, all cultivated citrus species (mandarin, orange, lemon, grapefruit), fig, loquat and ziziphus were detected as host plants of the Ceratitis capitata Wiedem. Among those found, in economic sense, the most important host plant is mandarin Unsiu. Intensity of the attack were monitored on mandarin in 2003 and 2004 in localities Baosici, Lastva Grbaljska and Bar, and was determined as higher in 2003. The first symptoms of attack were detected, depending on locality, from middle of September until beginning of October, one to two months earlier then in 2004. The maximum number of larvae per fruit were detected in October and November (average from 13.44?0.16 to 22.82?0.13). Time of the first symptoms appearence on mandarin in September and October 2003 and in November 2004, indicate on crucial importance of alternative host plants (figs and loquat) for reproduction and increasing of C. capitata population, because later during a season its intensity of attack on mandarin, depend largely on their presence.

Host Plant Species

Over a two–year period, we surveyed natural areas of the Mayan rainforest in Quintana Roo, Mexico. We found 11 species of Anastrepha Schiner (Diptera: Tephritidae) infesting 25 species of fruits belonging to ten plant families. We report the first records of 10 host plant species of the genus Anastrepha, which include the first report of a plant family (Putranjivaceae) serving as host of Anastrepha fraterculus (Wiedemann) infesting Drypetes lateriflora (Sw.) Krug and Urb. (Putranjivaceae). Pouteria reticulata (Engl.) Eyma (Sapotaceae) was found, for the first time, to be infested by Anastrepha serpentina (Wiedemann) and by a new undescribed species of Anastrepha. We also report Casimiroa microcarpa Lundell (Rutaceae) as a possible ancestral host for the Mexican fruit fly, Anastrepha ludens (Loew), in Central America. The family Sapotaceae was the best-represented host group with three fruit fly species recovered: A. serpentina, an economically-important species, found in eight host plants, and A. hamata and A. sp. (new species). We recorded six species of koinobiont parasitoids: Doryctobracon areolatus Szepligeti, Utetes (Bracanastrepha) anastrephae Viereck, Opius hirtus Fisher, and Doryctobracon zeteki Musebeck, (all Braconidae), and Aganaspis pelleranoi (Brethés) and Odontosema anastrephae Borgmeier, (both Figitidae). All these parasitoid species represent at least a new report for their host plants. Of the whole parasitoid community, D. areolatus was the most important parasitoid species with 52.7% of presence in 12 host plant species, parasitizing six fruit fly species. The interaction between fruit flies and their parasitoids with host plants depends on fruit availability, which is crucial for the survival of each of these species. Conserving the landscape of the Mayan rainforest is important not only for species conservation, but also for the maintenance of fruit fly host plants in orchard agroecosystems in southeastern Mexico.

Electroantennogram Recordings

The Mediterranean fruit fly, Ceratitis capitata Wied., is among the most serious pests in horticulture worldwide, due to its high reproductive potential, difficulty of control and broad polyphagy. The aim of this study was to measure—by means of the electroantennogram recordings— the antennal olfactory sensitivity of virgin, mated, male, female, lab-reared and wild C. capitata following stimulation with fruit and leaf headspace of some host-plants: clementine, orange, prickly pear, lemon and apple. The results show that: (a) lab-reared mated males are more sensitive to host-plant fruit and leaf headspace than females, while the opposite was true for wild insects; (b) antennae of wild virgin males were more sensitive than the mated ones, while no difference was observed among lab-reared medflies; (c) lab-reared virgin females were more sensitive than mated ones, while few differences were found within wild medflies; (d) in mated insects, lab-reared males were more sensitive to both host-plant fruits and leaves than the wild ones, while the opposite was found for females. Taken together, these results show that the olfactory sensitivity to host-plant odors differs between virgin and mated and lab-reared and wild flies.

The general aim of this study is to contribute to and summarize knowledge of the Bolivian fauna of the genus Anastrepha Schiner (Tephritidae) which includes species of both ecological and economic importance. In addition to compiling data from the literature, we report the results of fruit fly sampling using McPhail or multilure traps in the Tropic of Cochabamba region and at the private natural reserve of Potrerillo del Guendá in Santa Cruz de la Sierra, as well as records from various other sites based on specimens in museum collections. Fifty-seven named species and three unnamed species of Anastrepha are recorded from Bolivia. Distribution maps for all of these species are provided. Numerous new department records are reported as well as the first records for Bolivia of A. castanea Norrbom, A. dissimilis Stone, A. elegans Blanchard, A. haywardi Blanchard, A. macrura Hendel, A. montei Lima, A. punctata Hendel, and A. rosilloi Blanchard. Pacouria boliviensis (Markgr.) A. Chev. (Apocynaceae) is reported as a host plant of A. woodleyi Norrbom & Korytkowski, and Myrciaria floribunda (H. West ex Willd.) Berg (Myrtaceae) and Pouteria glomerata (Miq.) Radlk. (Sapotaceae) as host plants of A. fraterculus (Wiedemann). This distribution and host information will be useful to monitor and manage species that damage fruit crops in Bolivia.

Abstract The carnation tortrix moth, Cacoecimorpha pronubana (Hübner, [1799]) (Lepidoptera: Tortricidae), is one of the most economically important insect species affecting the horticultural industry in the UK. The larvae consume foliage, flowers or fruits, and/or rolls leaves together with silken threads, negatively affecting the growth and/or aesthetics of the crop. In order to understand the polyphagous behaviour of this species within an ornamental crop habitat, we hypothesized that different host plant species affect its life history traits differently. This study investigated the effects of the host plant species on larval and pupal durations and sizes, and fecundity (the number of eggs and the number and size of egg clutches). At 20°C, 60% RH and a 16L:8D photoperiod larvae developed 10, 14, 20 and 36 days faster when reared on Christmas berry, Photinia (Rosaceae), than on cherry laurel, Prunus laurocerasus (Rosaceae), New Zealand broadleaf, Griselinia littoralis (Griseliniaceae), Mexican orange, Choisya ternata (Rutaceae), and firethorn, Pyracantha angustifolia (Rosaceae), respectively. Female pupae were 23.8 mg heavier than male pupae, and pupal weight was significantly correlated with the duration of larval development. The lowest and the highest mean numbers of eggs were produced by females reared on Pyracantha (41) and Photinia (202), respectively. Clutch size differed significantly among moths reared on different host plants, although the total number of eggs did not differ. This study showed that different ornamental host plants affect the development of C. pronubana differently. Improved understanding of the influence of host plant on the moth's life history parameters measured here will help in determining the economic impact that this species may have within the ornamental plant production environment, and may be used in developing more accurate crop protection methodologies within integrated pest management of this insect.

AbstractRoot-associated entomopathogenic fungi (R-AEF) indirectly influence herbivorous insect performance. However, host plant-R-AEF interactions and R-AEF as biological control agents have been studied independently and without much attention to the potential synergy between these functional traits. In this study, we evaluated behavioral responses of cabbage root flies [Delia radicum L. (Diptera: Anthomyiidae)] to a host plant (white cabbage cabbage Brassica oleracea var. capitata f. alba cv. Castello L.) with and without the R-AEF Metarhizium brunneum (Petch). We performed experiments on leaf reflectance, phytohormonal composition and host plant location behavior (behavioral processes that contribute to locating and selecting an adequate host plant in the environment). Compared to control host plants, R-AEF inoculation caused, on one hand, a decrease in reflectance of host plant leaves in the near-infrared portion of the radiometric spectrum and, on the other, an increase in the production of jasmonic, (+)-7-iso-jasmonoyl-l-isoleucine and salicylic acid in certain parts of the host plant. Under both greenhouse and field settings, landing and oviposition by cabbage root fly females were positively affected by R-AEF inoculation of host plants. The fungal-induced change in leaf reflectance may have altered visual cues used by the cabbage root flies in their host plant selection. This is the first study providing evidence for the hypothesis that R-AEF manipulate the suitability of their host plant to attract herbivorous insects.
