 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Suitability of Different Mealybug Species (Hemiptera: Pseudococcidae) as Hosts for the Newly Identified Parasitoid Allotropa suasaardi Sarkar & Polaszek (Hymenoptera: Platyg ผู้เขียน:M. A. Sarkar, ดร.วิวัฒน์ เสือสะอาด, รองศาสตราจารย์ , ดร.โสภณ อุไรชื่น, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractThe parasitoid Allotropa suasaardi Sarkar & Polaszek (Hymenoptera: Platygasteridae) was recently described from a series of specimens reared from Phenacoccus manihoti Matile-Ferrero on cassava (Manihot esculenta Crantz) in a field in Kanchanaburi province, Thailand. It is currently being evaluated as a biological control agent of the cassava mealybug complex. In order to understand host/parasitoid ecological interactions and optimize the mass-production system of this parasitoid, nine mealybug species (P. manihoti, Pseudococcus jackbeardsleyi Gimpel & Miller, Ferrissia virgata (Cockerell), Phenacoccus madeirensis Green, Planococcus citri (Risso), Dysmicoccus neobrevipes Beardsley, Coccidohystrix insolita (Green), Rastrococcus spinosus (Robinson) and Paracoccus marginatus Williams & Granara de Willink) widespread in Thailand, were tested to determine their potential as alternative hosts for the parasitoid. A set of tests was conducted in the laboratory on susceptibility, preference and suitability. Successful parasitization and the development of progeny were obtained with four mealybug species, D. neobrevipes, P. manihoti, P. madeirensis and P. jackbeardsleyi; the other mealybug species were not utilized by the parasitoid. A. suasaardi accepted multiple species for development, with the ranking of species preference, from the most to the least being D. neobrevipes, P. manihoti, P. madeirensis and P. jackbeardsleyi. The mean developmental time was shorter and a higher number of progeny were produced in D. neobrevipes mealybug species followed by P. manihoti. The results presented in this study show some of the range of hosts available for A. suasaardi Sarkar & Polaszek in Thailand. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Evaluation of Parasitism Capacity of Megastigmus thitipornae Dog?nlar & Hassan (Hymenoptera: Torymidae), the Local Parasitoid of Eucalyptus Gall Wasp, Leptocybe invasa Fishe ผู้เขียน:ดร.เบญจคุณ แสงทองพราว, ผู้ช่วยศาสตราจารย์ , นายโกศล เจริญสม, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractMegastigmus thitipornae Dog?nlar & Hassan is the local parasitoid of Leptocybe invasa Fisher & La Salle, which is a devastating pest of Eucalyptus camaldulensis Dehn. in Thailand. This research aimed to evaluate the parasitism capacity of M. thitipornae. The experiments were undertaken in the laboratory and the greenhouse. The results from feeding adult M. thitipornae with six different diets (nine replications per treatment and ten parasitoids per replication) in the laboratory showed that diets had highly significant effects on the means of longevity of female and male parasitoids (P < 0.01, P < 0.01, respectively). A honey solution diet could extend the mean longevity of females to 9.83 ? 0.60 d (mean ? SE) and that of males to 7.83 ? 0.48 d. Estimated 50% female and male survival periods, when fed with the honey solution diet, were 8 and 4 d, respectively. The average potential fecundity (egg load) of females was 2.98 ? 0.11 eggs per female. The average female size (hind tibia length) was 0.31 ? 0.002 mm. In the greenhouse, the mean realized fecundity of females was 13.20 ? 1.95 progeny per female. M. thitipornae was identified as a synovigenic species. The progeny of this parasitoid had a male-biased sex ratio. M. thitipornae parasitized on the mature larva and pupa of the host. The single egg of this parasitoid developed as a solitary ectoparasitoid and completed its development outside the host body. The mean developmental time of M. thitipornae from the egg to the adult stage was 17 ? 0.44 d. When the above biological parameters of M. thitipornae were evaluated with those of L. invasa from a previous study, the results indicated that M. thitipornae had less parasitism capacity to control eucalyptus gall wasp (L. invasa) in Thailand. |
