As part of research to identify host-based attractants for X. glabratus, we discovered that a diverse array of non-target ambrosia beetles was attracted to the same substrates as X. glabratus. During Sep-Dec 2009, several field tests were conducted in north Florida (in woodlands with advanced stages of laurel wilt) with traps baited with commercial lures of the essential oils, manuka and phoebe, and with freshly-cut wood bolts of avocado (a known host) and lychee (Litchi chinensis, a non-host high in the sesquiterpene [alpha]-copaene, a putative host attractant). In addition, manuka-baited traps were deployed in avocado groves in south Florida to monitor for potential spread of X. glabratus. The combined trapping results indicated that none of these substrates was specific in attraction of X. glabratus. Numerous non-target ambrosia beetles were captured, including 17 species representative of 4 tribes within the subfamily Scolytinae. This report provides photo-documentation and data on the species diversity and relative abundance for a group of poorly-studied beetles, the scolytine community in Florida Persea habitats.10aXyleborus glabratus1 aKendra, Paul, E.1 aSanchez, Jorge, S.1 aMontgomery, Wayne, S.1 aOkins, Katherine, E.1 aNiogret, Jerome1 aPena, Jorge, E.1 aEpsky, Nancy, D.1 aHeath, Robert, R.  uhttps://weevil.myspecies.info/diversity-scolytinae-coleoptera-curculionidae-attracted-avocado-lychee-and-essential-oil-lures02742nas a2200241   4500008004100000020001400041245011100055210006900166260000800235300001200243490000700255520191500262653002402177100002102201700002602222700002002248700002002268700002302288700001902311700002102330700002202351856012702373       2011                        eng d  a0098-033100aAttraction of the Redbay Ambrosia Beetle, Xyleborus glabratus, to Avocado, Lychee, and Essential Oil Lures0 aAttraction of the Redbay Ambrosia Beetle Xyleborus glabratus to   cSep  a932-9420 v373 aThe redbay ambrosia beetle, Xyleborus glabratus Eichhoff, is an exotic wood-boring insect that vectors the mycopathogen responsible for laurel wilt, a lethal vascular disease of trees in the Lauraceae. High mortality has occurred in native Persea species in the southeastern U. S., and the vector-pathogen complex poses an imminent threat to the production of commercial avocado, P. americana, in south Florida. There is a critical need for effective attractants to detect, monitor, and control this invasive pest. This study combined field tests and laboratory bioassays to evaluate the response of female X. glabratus to host-based volatiles from wood of avocado (cultivars of West Indian, Guatemalan, and Mexican races); from wood of lychee (Litchi chinensis, a presumed non-host that is high in the sesquiterpene [alpha]-copaene, a putative attractant); and to commercial lures containing manuka and phoebe oils, two reported attractive baits. Volatile collections and GC-MS analyses were performed to quantify the sesquiterpene content of test substrates. In the field, traps baited with lychee wood captured more beetles than those with wood from avocado cultivars; traps baited with phoebe oil lures captured more beetles than those with manuka oil lures (the current monitoring tool). In field and laboratory tests, X. glabratus did not show a preference among avocado races in either attraction or host acceptance ( initiation of boring). In choice tests, lychee was more attractive than avocado initially, but a higher percentage of beetles bored into avocado, suggesting that lychee emits more powerful olfactory/visual cues, but that avocado contains more of the secondary cues necessary for host recognition. Emissions of [alpha]-copaene, [beta]-caryophyllene, and [alpha]-humulene were correlated with field captures, and lychee wood may be a source of additional semiochemicals for X. glabratus.10aXyleborus glabratus1 aKendra, Paul, E.1 aMontgomery, Wayne, S.1 aNiogret, Jerome1 aPena, Jorge, E.1 aCapinera, John, L.1 aBrar, Gurpreet1 aEpsky, Nancy, D.1 aHeath, Robert, R.  uhttps://weevil.myspecies.info/attraction-redbay-ambrosia-beetle-xyleborus-glabratus-avocado-lychee-and-essential-oil-lures01391nas a2200181   4500008004100000020001400041245012000055210006900175260000800244300001200252490000800264520072600272653001400998100002301012700002001035700001901055856013501074       2007                        eng d  a0013-874600aMorphology and development of immature stages of Fidiobia dominica (Hymenoptera: Platygastridae: Sceliotrachelinae)0 aMorphology and development of immature stages of Fidiobia domini  cMay  a413-4170 v1003 aThe external morphology and development of immature stages of Fidiobia dominica Evans & Pena (Hymenoptera: Platygastridae), a Neotropical solitary endoparasitoid of the eggs of Diaprepes spp. (Coleoptera: Curculionidae), are reported.

It is a highly polyphagous species which can complete its entire life cycle on citrus and several woody ornamental plants. The lack of native egg parasitoids for this weevil in citrus orchards has triggered efforts to evaluate candidate egg parasitoids from the Caribbean Region into Florida. The egg parasitoids Fidiobia dominica and Haeckeliania sperata are two exotic natural enemies of D. abbreviatus recently introduced in the US in a classical biological control program. The thermal requirements of both parasitoids were studied in the laboratory. The upper development threshold (UDT) of F. dominica was 30.0[degree]C, itsmaximal development rate (MDR) occurred at 27.6[degree]C, its lower development threshold (LDT) was 9.6[degree]C and its thermal constant (K) for development from egg to adult was 293.1 DD. For H. sperata, UDT was 35.0[degree]C, MDR occurred at 31.0[degree]C, LDT was around 15[degree]C and K was 188.1 DD. Based on these results, both species would be able to complete 17 to 18 generations annually in southern Florida. However, host availability during critical periods could severely impair the ability of these egg parasitoids to establish and successfully control D. abbreviatus in areas where winter temperatures fluctuate around 12[degree]C, the LDT for this pest.10aDiaprepes abbreviatus1 aJacas, Josep, A.1 aPena, Jorge, E.1 aDuncan, Rita, E.1 aUlmer, Bryan, J.  uhttps://weevil.myspecies.info/thermal-requirements-fidiobia-dominica-hymenoptera-platygastridae-and-haeckeliania-sperata-hymenopte02323nas a2200193   4500008004100000020001400041245018200055210006900237260000800306300001200314490000700326520155300333653002601886100002101912700002101933700002101954700002001975856013401995       2010                        eng d  a1049-964400aThe role of Brachyufens osborni (Hymenoptera: Trichogrammatidae) in the classical biological control program against Diaprepes abbreviatus (Coleoptera: Curculionidae) in Florida0 arole of Brachyufens osborni Hymenoptera Trichogrammatidae in the  cSep  a213-2200 v543 aBrachyufens osborni is an indigenous egg parasitoid of weevil species laying concealed eggs in Florida. Diaprepes abbreviatus, an exotic weevil pest of different crops in the southern USA, has been reported as a host for B. osborni. In this study we investigated the interaction between B. osborni and D. abbreviatus as well as other hosts including Pachnaeus litus and Artipus floridanus. The thermal requirements of B. osborni and the interaction between this species and three other weevil parasitoids introduced in a classical biological control program against D. abbreviatus (Aprostocetus vaquitarum, Haeckeliania sperata and Quadrastichus haitiensis) were also examined in laboratory studies. Although B. osborni attacked eggs of all weevil species tested, it could not complete development on D. abbreviatus. The three exotic parasitoids did successfully develop on both P. litus and D. abbreviatus eggs, though our results showed that P. litus should not be considered as an alternative host for the introduced parasitoids during winter in central Florida. Because B. osborni cannot complete development on D. abbreviatus, it has never been recovered from field collected hosts, and its effect on D. abbreviatus in the field remains ignored. This study demonstrates that although B. osborni could not successfully develop in D. abbreviatus, it can inflict important mortality to it and suggests that B. osborni could impact the establishment of introduced D. abbreviatus egg parasitoids.

Haeckeliania sperata Pinto is a gregarious endoparasitoid that attacks D. abbreviates eggs. We hypothesized that the reproductive success of H. sperata is affected by the host plant of D. abbreviates. Six host plants with varying degrees of pubescence were used to determine the effect of leaf trichomes on the searching behavior and success of parasitism by H. sperata. No-choice tests showed that H. sperata was able to parasitize Diaprepes eggs laid on the six host plants. However, the plants with a high trichome density on their leaves had a lower percent of parasitism than the plants with smoother leaves. Removing trichomes from a host plant showed that the presence of some leaf trichomes had a negative effect on the overall searching efficiency of H. sperata. The presence of trichomes decreased the total distance traveled and increased the total search time of IT sperata females, resulting in a lower searching speed. Multiple regression analysis was used to establish the relationship between percent parasitism and leaf trichome density, leaf thickness, and the searching speed of H. sperata. Searching speed was the best predictor of percent parasitism; this parameter could be used to predict the suitability of host plants for the establishment of H. sperata. Our findings suggest that the reproductive success of H. sperata is affected by the host plant of D. abbreviatus.10aDiaprepes abbreviatus1 aCarrillo, Daniel1 aPena, Jorge, E.1 aCapinera, John, L.  uhttps://weevil.myspecies.info/effect-host-plants-successful-parasitism-haeckeliania-sperata-hymenoptera-trichogrammatidae-diaprepe
