In a field study in Hawaii, color-marked protein-deprived and protein-fed female melon flies, Bactrocera cucurbitae Coquillett, were released within canopies of unsprayed sorghum plants (a nonhost flies) outside border area or bait-sprayed open space that surrounded cucumbers, favored host flies. Application bait spray to sugarcane surrounding flies is common practice for fly control Hawaii. GF-120 Fruit Fly Bait proved very effective preventing females from alighting on cucumbers (23%...

Abstract Blends of volatile compounds emitted by host plants are known to mediate the attraction gravid female herbivores oviposition sites, but role individual odor components is still little understood. We characterized olfactory response mated Cydia (Grapholita) molesta (Busck) (Lepidoptera: Tortricidae) synthetic mixtures peach shoot, a key plant this herbivore, and investigated important constituents bioactive in moth attraction. Relative ratios corresponded natural ratio collected...

The efficacy of GF-120 NF Naturalyte Fruit Fly Bait in combination with field sanitation was assessed as a control for female oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), papaya (Carica L.) orchards Hawaii. Three different bait spray regimes were evaluated: every row (high use the bait), fifth (moderate use), and 10th (low use). Orchard plots which no applied served controls. For five seven biweekly periods that followed first spray, trapping data revealed...

Application of bait spray to non-host sorghum plants bordering host melon flies, Bactrocera cucurbitae Coquillet, is a common practice for fly control in Hawaii. In field study conducted 2003 Hawaii, we first asked whether GF-120 Fruit Fly applied that bordered only two (opposite) sides patch cucumbers was as effective protecting against flies similar all four cucumber patch. Second, mature females carrying high egg load but deprived protein during the previous 24 h were more responsive than...

Abstract In a series of studies conducted in Hawaii under seminatural conditions, we quantified the response sexually mature, host‐seeking female melon flies, Bactrocera cucurbitae (Coquillett) (Diptera: Tephritidae), to different types visual and chemical host‐associated stimuli with main aim developing monitoring device for females. Experiments were using Tangletrap‐coated fruit mimics either spherical (8 cm diameter) or cylindrical (4.3 diameter; 15 length) shapes coated artificial color...

Abstract The attractiveness of peach ( Prunus persica L. Batsch) and apple Malus domestica Borkh.) (both Rosaceae) tissue to gravid female oriental fruit moth, Grapholita (= Cydia ) molesta (Busck) (Lepidoptera: Tortricidae), was assessed at three distinct stages throughout the growing season using a dual‐choice bioassay. Plant material offered moths consisted plant shoot in early spring, before became available. Later, it leaf‐bearing twig fruit, either alone or combination. level...

Methyl eugenol (ME) and cue-lure (C-L) traps with solid lure dispensers were deployed in areas low high populations of oriental fruit fly, Bactrocera dorsalis (Hendel), melon cucurbitae (Coquillett), respectively. In low-density areas, standard Jackson or Hawaii Fruit Fly Areawide Pest Management (AWPM) FT Mallet ME wafers impregnated dimethyl dichloro-vinyl phosphate (DDVP) AWPM Scentry cones vapor tape performed equally as well liquid ME/C-L naled. Standard C-L DDVP plugs a lure-naled...

The United States Department of Agriculture's Agricultural Research Service initiated an area-wide fruit fly management program in Hawaii 2000. first demonstration site was established Kamuela, Hawaii, USA. This paper documents suppression the Mediterranean fly, Ceratitis capitata (Wiedemann), and oriental Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), a 40 km2 area containing urban, rural agricultural zones during 6 year period. techniques included sanitation, GF-120 NF Naturalyte...

Rhopalosiphum padi (L.) (Hemiptera: Aphididae) is one of the most significant cereal pests worldwide. Control R. has relied heavily on chemical insecticides. We sampled 12 populations from 11 provinces in China and analyzed their regional susceptibilities to 10 insecticides by using leaf dip method. The showed susceptibility or minor resistance chlorpyrifos, malathion, thiamethoxam, beta-cypermethrin, acetamiprid, pymetrozine, but moderate bifenthrin, decamethrin, abamectin. Correlation...

Abstract The objectives of this study were to quantify the virulence four entomopathogenic fungal species pupae Rhagoletis pomonella (Walsh) (Diptera: Tephritidae) and determine potential combine fungi (EPFs) nematodes (EPNs) for biological control pest. EPFs included Beauveria bassiana (strain GHA), Metarhizium brunneum F52), Isaria javanica (wf GA17), fumosorosea (Apopka 97 strain). In laboratory assays, all reduced adult emergence but there no differences between species. M. examined...

Specialized Pheromone and Lure Application Technology (SPLAT) methyl eugenol (ME) cue-lure (C-L) "attract-and-kill" sprayable formulations containing spinosad were compared with other under Hawaiian weather conditions against oriental fruit fly, Bactrocera dorsalis (Hendel), melon cucurbitae (Coquillett) (Diptera: Tephritidae), respectively. Field tests conducted three different dispensers (Min-U-Gel, Acti-Gel, SPLAT) two insecticides (naled spinosad). SPLAT ME was equal in performance to...

Abstract A novel, visually‐attractive bait station was developed in Hawaii for application of insecticidal baits against oriental fruit fly, Bactrocera dorsalis (Hendel), melon cucurbitae (Coquillett), and Mediterranean Ceratitis capitata (Wiedemann) (all Diptera: Tephritidae). The represents a supernormal visual stimulus papaya foliage takes advantage the flies’ strong response to high light‐reflecting properties yellow color their need shelter, while fully protecting rainfall. Field...

The peach fruit fly, Bactrocera zonata, and the Oriental B. dorsalis (Diptera: Tephritidae), are economically important fly species in various regions of world. We evaluated effects separate combined applications entomopathogenic fungi (EPF) Beauveria bassiana (WG-18) Metarhizium anisopliae (WG-02), nematodes (EPNs) Heterorhabditis bacteriophora (VS strain) Steinernema carpocapsae (ALL against larvae, pupae pharate adults, zonata under laboratory, glasshouse field cage conditions.Combined...

Abstract Aphis spiraecola Patch is one of the most economically important tree fruit pests worldwide. The pyrethroid insecticide lambda-cyhalothrin commonly used to control A. . In this 2-year study, we quantified resistance level in different regions Shaanxi province, China. results showed that had reached extremely high levels with a 174-fold ratio (RR) found Xunyi region. addition, compared enzymatic activity and expression P450 genes among eight populations. was significantly increased...

Anastrepha fraterculus (Wiedemann) is recognized as a pest of citrus, apples, and blackberries in South America. In Mexico, it mainly found fruit the family Myrtaceae has never been reported infesting citrus. Here, we sought to determine whether females stemming from Mexican A. populations (collected state Veracruz) would lay eggs 'Valencia' oranges 'Ruby Red' grapefruit and, if so, larvae hatch develop. We worked under laboratory seminatural conditions (i.e., gravid released fruit-bearing,...

We designed 2 papaya groves to test the concepts of trap cropping and border trapping control Toxotrypana curcicauda. Intensive fruit sampling in grove 1 indicated that degree infestation decreased as distance from native vegetation (source flies) increased. Rows planted 10 m away main block trees (trap crop) exhibited greatest puncture damage larval both experimental groves. Fruit was highest after rainy season over spatially aggregated. conclude designing a such way crop consisting plants...
