Identification of protein related to dietary vitamin B deficiency in Mediterranean fruit fly larvae.

Mediterranean fruit fly (medfly), , is among the most destructive agricultural pest. The sterile insect technique (SIT) can effectively control medfly populations. To rear healthy medflies for the purpose of SIT, it is essential to supplement B vitamins in the diet.

Construction of Highly Efficient Carbazol-9-yl-Substituted Benzimidazole Bipolar Hosts for Blue Phosphorescent Light-Emitting Diodes: Isomer and Device Performance Relationships.

Four isomers of carbazol-9-yl-substituted 1,2-diphenylbenzimidazole at 7, 6, 5, and 4 positions, named as 1-CbzBiz, 2-CbzBiz, 3-CbzBiz, and 4-CbzBiz, respectively, have been synthesized. Instead of having an identical molecular weight, the CbzBiz's have their glass transition temperatures ( T) spanning a large range from 53 to 90 °C. Their T and melting point ( T) basically obey the Boyer-Kauzmann rule ( T = g· T with g ≈ 0.

Comparative Proteomic Profiling between Each of Two Consecutive Developmental Stages of the Solanum Fruit Fly, (Hendel).

The Solanum fruit fly, (Hendel), has a complex life cycle including multiple stages (egg, larva, pupa, and adult). Understanding the details of “what„, “when„, “where„, “why„, and “how„ many hundred thousand proteins operate in this insect, interact, and express between each two consecutive developmental stages at molecular level not only can expand our knowledge, but also lead to the development of novel fruit fly control techniques. We tried to find what, when, and where in this study.

Laboratory evaluation on a potential birth control diet for fruit fly sterile insect technique (SIT).

Sterile insect technique (SIT) is one of the most effective fruit fly control technologies. Irradiation has been used to sterilize male fruit flies before release to the field to compete with the wild males for females. Imagine an environmental and cost effective method using a rearing diet that can make insects sterile indefinitely, by feeding for 7days before release.

LARVAL X-RAY IRRADIATION INFLUENCES PROTEIN EXPRESSION IN PUPAE OF THE ORIENTAL FRUIT FLY, BACTROCERA DORSALIS.

The sterile insect technique (SIT) was developed to eradicate the new world screwworm from the southern United States and Mexico, and became a component of many area-wide integrated pest management programs, particularly useful in managing tephritid fruit flies. SIT is based on the idea of rearing and sterilizing male pests, originally by ionizing radiation, and then releasing into field, where they compete for and mate with wild females. Mating with sterile males leads to reduced fecundity to lower pest populations.

Pyrrolo-[3,2-b]pyrroles for Photochromic Analysis of Halocarbons.

Dramatic photochromic-change of 2,5-bis(triphenylamine)-substituted N,N'-diphenylpyrrolo-[3,2-b]pyrrole (1) with halocarbons provides an effective route for halocarbon analysis with the naked eye. The visual detection range can reach as low as 10(-4) ∼ 10(-5) M (1-10 ppm) in CH3CN. This method can also be applied for detection of CHCl3 in water.

Pupal X-ray irradiation influences protein expression in adults of the oriental fruit fly, Bactrocera dorsalis.

The oriental fruit fly, Bactrocera dorsalis, is a pest of fruit in the Asia-Pacific region and also, due to quarantine restrictions, a threat to California fruit production. Area-wide suppression of B. dorsalis integrated several approaches including the sterile insect technique (SIT).

A qPCR-based method for detecting parasitism of Fopius arisanus (Sonan) in oriental fruit flies, Bactrocera dorsalis (Hendel).

Background: Parasitism detection and species identification are necessary in fruit fly biological control. Currently, release of mass-reared Fopius arisanus is practiced worldwide, as it is effective in controlling Bactrocera dorsalis and Ceratitis capitata. To detect and assess parasitism in parasitoid mass-rearing colonies and parasitism levels in field populations across all life stages of hosts, the development of a rapid, specific and sensitive method is important.

Tunable electrofluorochromic device from electrochemically controlled complementary fluorescent conjugated polymer films.

The fluorescent behavior of the electrofluorochromic devices (Type I) of greenish-yellow emitting P1 and blue emitting P2 can be reversibly switched between the nonfluorescent (oxidized) state and the fluorescent (neutral) state with a superb on/off ratio of 23.8 and 21.9, respectively.

Dietary lufenuron reduces egg hatch and influences protein expression in the fruit fly Bactrocera latifrons (Hendel).

Lufenuron (LFN), a chitin synthase inhibitor, impacts the fertility of Ceratitis capitata, Bactrocera dorsalis, B. cucurbitae, and B. latifrons.

Diet-induced over-expression of flightless-I protein and its relation to flightlessness in Mediterranean fruit fly, Ceratitis capitata.

The Mediterranean fruit fly (medfly), Ceratitis capitata is among the most economically important pests worldwide. Understanding nutritional requirement helps rearing healthy medfly for biocontrol of its population in fields. Flight ability is a high priority criterion.

Resveratrol modifies tephritid fruit fly response to radiation but not nutritional stress.

Purpose: Resveratrol (3,5,4'-trihydroxystilbene) is a polyphenol compound found in many plants and fruits that has antioxidant and radioprotective properties. Two model invertebrates, Bactrocera dorsalis (oriental fruit fly) and B. cucurbitae (melon fly) (Diptera: Tephritidae), were studied to determine if the addition of resveratrol to an artificial diet could modify their response to radiation and nutritional stress.

Dietary wheat germ oil influences gene expression in larvae and eggs of the oriental fruit fly.

Changes in animal nutrition, particularly essential dietary components, alter global gene expression patterns. Our goal is to identify molecular markers that serve as early indicators of the quality of insect culture media. Markers of deficient culture media will increase the efficiency of developing optimal systems for mass rearing beneficial insects and some pest species because decisions on culture media quality can be made without waiting through one or several life cycles.

Wheat germ oil in larval diet influences gene expression in adult oriental fruit fly.

Culture medium supplemented with wheat germ oil (WGO) causes physiological reactions, such as increased fecundity and mobility, in some insects. Although the impact of WGO on insect physiology is important, the mechanisms of these actions are poorly understood. In this paper, we test the hypothesis that the addition of WGO to medium developed for larval oriental fruit flies modulates gene expression in the corresponding adults.

Evaluation of yeasts and yeast products in larval and adult diets for the oriental fruit fly, Bactrocera dorsalis, and adult diets for the medfly, Ceratitis capitata, and the melon fly, Bactrocera curcurbitae.

Several yeasts and yeast products were tested in adult diets for the medfly Ceratitis capitata (Wiedemann), oriental fruit fly Bactrocera dorsalis (Hendel), and melon fly, Bactrocera curcurbitae (Coquillett) (Diptera: Tephritidae) and in larval liquid diet for mass-rearing B. dorsalis. Three hydrolyzed brewer's yeasts (FNILS65, FNI200 and FNI210), one glutamine enriched yeast (GSH), one vitamin-enriched yeast (RDA500), Korea yeast, whole cell yeasts, and combinations of them were evaluated.

Insecticidal activity of basil oil, trans-anethole, estragole, and linalool to adult fruit flies of Ceratitis capitata, Bactrocera dorsalis, and Bactrocera cucurbitae.

Basil oil and its three major active constituents (trans-anethole, estragole, and linalool) obtained from basil (Oscimum basilicum L.) were tested on three tephritid fruit fly species [Ceratitis capitata (Wiedemann), Bactrocera dorsalis (Hendel), and Bactrocera cucurbitae (Coquillett)] for insecticidal activity. All test chemicals acted fast and showed a steep dose-response relationship.

Wheat germ oil and its effects on a liquid larval rearing diet for oriental fruit flies (Diptera: Tephritidae).

Wheat germ oil was added to a larval liquid diet for rearing Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) to optimize fruit fly quality. Effects of various concentrations of wheat germ oil at 0.04, 0.
