Journal of economic entomology 2018 v.111 no.3 pp. 1151-1156
ISSN:

Subject:
Curculionidae; Cylas formicarius elegantulus; adults; insect pests; insemination; irradiation; males; spermatozoa; spermiogenesis; sterile insect technique; survival rate; sweet potatoes
Abstract:
... The sterile insect technique (SIT) has been used for the control or eradication of target insect pests. To successfully apply SIT, it is very important to clarify the effect of irradiation on male reproduction in the target pest, because their mating and spermiogenesis abilities affect the success of eradication program. The sweetpotato weevil, Cylas formicarius (Fabricius) (Coleoptera: Brentidae) ...

Abstract:
... Fifty-nine sweetpotato cultivars, including 16 heirlooms, 11 near-heirlooms (developed in the 1960s and 1970s), 19 cultivars from the 1980s, and 13 modern varieties (since 1990), were evaluated for resistance to soil insects in field experiments during 2010–2011 at the U.S. Department of Agriculture-Agriculture Research Service, U.S. Vegetable Laboratory (USDA-ARS, USVL), Charleston, SC. These exp ...

3. Is Elytral Color Polymorphism in Sweetpotato Weevil (Coleoptera: Brentidae) a Visible Marker for Sterile Insect Technique?: Comparison of Male Mating Behavior

Subject:
Curculionidae; Cylas formicarius elegantulus; artificial selection; behavior change; color; dyes; elytra; inbreeding depression; insect pests; males; mating behavior; monitoring; sterile insect technique; survival rate; Japan
Abstract:
... The sterile insect technique (SIT) is widely used for suppressing or eradicating target pest insect populations. In the eradication programs using the SIT, a large number of sterile insects are marked and released in the field. In Japan, Cylas formicarius (F.) group (Coleoptera: Brentidae) weevils are marked with a fluorescent powder dye to monitor the progress of such programs. However, this moni ...

4. Assessment of Effect of Partial Sterility on Mating Performance in Sweetpotato Weevil (Coleoptera: Curculionidae)

Journal of economic entomology 2010 v.103 no.6 pp. 2034–2041

Subject:
Curculionidae; Cylas formicarius elegantulus; females; gamma radiation; germ cells; insect pests; irradiation; males; mating competitiveness; reproductive performance; somatic cells; sterile insect technique; Ryukyu Archipelago
Abstract:
... The sterile insect technique (SIT) is widely used to suppress or eradicate target pest insect populations. Although the effectiveness of SIT depends on the ability of released sterile males to mate with and inseminate wild females, the use of gamma radiation to induce sterility negatively impacts reproductive cells as well as somatic cells. Consequently, sterilization by irradiation drastically di ...

Abstract:
... Inadvertent selection is an important genetic process that frequently occurs during laboratory culture and maintenance of biological control agents and other beneficial organisms used in procedures such as the sterile insect technique (SIT). We investigated effects of mass rearing and inbreeding depression on life history traits (number of progeny emerging from host plants, body weight, developmen ...
