Does Diachasmimorpha longicaudata Hymenoptera: Braconidae have a preferential instar to parasitize Tephritidae Diptera? Roberta A. Simone M. Luiza R. Diachasmimorpha longicaudata Ashmead, is a koinobiont parasitoid of Tephritidae larvae, the third instar larvae of which is considered preferential, but it is able to parasitize other larval stages and compete with native parasitoids. This study investigated the preference and parasitism capacity of D.

Diachasmimorpha longicaudata is a solitary species of parasitoid wasp and an endoparasitoid of tephritid fruit fly larvae. It is now considered the most extensively used parasitoid for biocontrol of fruit flies in both the southern portion of the United States and Latin America. This has resulted in quarantines on grapefruit shipped internationally as well as domestically. It is likely multiple biological species separated by both reproductive isolation and morphological characteristics such as wing geometry.
Diachasmimorpha longicaudata originated in the Indo-pacific region of Asia. The genus Diachasmimorpha has traditionally been defined by the morphology of their apically sinuate ovipositor. The adult male is smaller than the female with a body length of up to 4. The body is a reddish-brown color and antennae are longer than the body. Wings are clear.
Females have a long ovipositor. The gaster of males and females differs slightly with the female having a dorsal central black band while the gaster of the male has a dark brown to black dorsal posterior.
Three cryptic species have been identified within D. Subspecies have also been reported based on differing geographical areas with high variation being associated variation of resources.
Both males and females are solitary. Third instar t ephritid fruit fly larvae are the typical hosts. Females lay eggs per day using her elongated ovipositor to reach the fly larvae. Typically only one egg is laid per instar larvae with exceptions when hosts are insufficient; however only one pupa will reach maturity.
Diachasmimorpha longicaudata entomopoxvirus DlEPV is a notable symbiotic virus that affects Diachasmimorpha longicaudata. These viruses are found within the adult wasps and retained in subsequent generations. From Wikipedia, the free encyclopedia. Diachasma longicaudata Female D. Florida Entomologist.

Diachasmimorpha formerly Biosteres or Opius longicaudata Ashmead Wharton is a solitary braconid wasp parasitoid of Caribbean fruit fly , Anastrepha suspensa Loew , larvae. The Caribbean fruit fly belongs to a group of major fruit pests that occur in the New World tropics and subtropics. Caribbean fruit flies, which infest more than 80 species of fruit, were accidently introduced into southern Florida in This has raised concern because the fly will oviposit in very ripe citrus fruits, threatening foreign markets in countries where the fly has not been detected. It resulted in establishment of quarantines on fruit shipped to Japan, as well as on interstate shipments to Arizona, California, Hawaii and Texas. Fruit must be fumigated, undergo cold treatment, or be shipped from protocol areas fly-free or bait-sprayed.
Metrics details. Diachasmimorpha longicaudata Hymenoptera: Braconidae is a solitary parasitoid of Tephritidae Diptera fruit flies of economic importance currently being mass-reared in bio-factories and successfully used worldwide. A peculiar biological aspect of Hymenoptera is its haplo-diploid life cycle, where females diploid develop from fertilized eggs and males haploid from unfertilized eggs. Diploid males were described in many species and recently evidenced in D. Sex determination in this parasitoid is based on the Complementary Sex Determination CSD system, with alleles from at least one locus involved in early steps of this pathway. Since limited information is available about genetics of this parasitoid species, a deeper analysis on D. We report here the first transcriptome analysis of male-larvae, adult females and adult males of D.
