Abstract:

The sweetpotato weevil (SPW) [Cylas formicarius elegantulus (Summers) (Coleoptera: Curculionidae)] is the single most devastating pest of the sweetpotato [Ipomoea batatas (L.) Lam.] worldwide. Attempts to develop host-plant resistance have been only moderately successful due in part to deficiencies in parent and progeny selection methods. Host-plant phytochemicals play critical roles in insect behavior, modulating a cross-section of key behavioral decisions. Thus, identification of the phytochemicals the female weevil uses in decision making could greatly facilitate development of host-plant r

Abstract:

Narrow-sense heritabilities (h2) for sweetpotato weevil (Cylas formicarius elegantulus) resistance were estimated in 2 breeding populations. Population A included clones from US programs with previously reported moderate levels of weevil resistance. Population B included clones of US origin plusplant introductions from 14 countries. Parents and progenies were included in field evaluations with no wild weevils present. Weevils were cultured and applied to each plant. Population A was evaluated for 2 years and population B for 1. The GXE estimate for population A was also used for population B.

Abstract:

Levels of major root surface components for two sweetpotato [Ipomoea batatas (L.) Lam.] cultivars that differ in susceptibility to the sweetpotato weevil [Cylas formicarius elegantulus (Summers)] were determined. Analyses were made 30 days before harvest, at harvest, after curing, and after 2 months of storage during two seasons. Significant variation in the amounts of individual components, especially boehmeryl acetate, which is known to be an ovipositional stimulant for the weevil, was found before and after harvest, with season, and between cultivars. These results suggest that variation in

Abstract:

A study was conducted to evaluate the effect of irrigation on yield and sweetpotato weevil (SPW) infestation of sweetpotato storage roots. Sweetpotato was grown in plots under controlled soil moisture regimes. The treatments were rainfed (no applied irrigation) and irrigation applied to maintain soil moisture levels at 20, 40, and 60 kPa, based on tensiometer readings. The 40- and 60-kPa treatments produced the highest yield of root biomass. Irrigation applied at 40 kPa produced significantly more medium-sized storage roots (8.1 t·ha–1) than the rain-fed treatment, which produced 4.4 t·ha–1. A

Abstract:

Ultrasensitive acoustical equipment was used to detect larvae of the sweetpotato weevil, Cylas formicarius elegantulus (Summers) (Coleoptera: Curculionidae), in the sweet potato, Ipomoea batatas (L.). Methods of expressing results were evaluated with per cent audible as the best indicator of larval presence. Sound from moderately infested sweet potatoes (8 to 20 weevils/sweet potato) varied considerably even though infestation rates above 60 weevils/sweet potato resulted in sound throughout most of the observation period. Infested sweet potatoes were detectable after two weeks of weevil develo

Abstract:

Methodology was developed for the extraction of surface components of sweetpotato [Ipomoea batatas (L.) Lam.] storage roots. Surface components of storage roots were quantitatively extracted with methylene chloride using 8-minute ultrasonication. After removal of the solvent, the extract was treated with 3 Tri Sil-Z:1 trimethylsilylimidazol (v/v) to convert components with hydroxyl moieties to silyl ethers and then separated on a SE-54 fused silica capillary column. Distinctly different gas chromatography profiles were found between lines displaying moderate levels of resistance (`Resisto', `R

<p>The efforts of production enhancement of sweet potato are limited by some constraints including some pest. One of the important pests is sweet potato weevil (Cylas formicarius Fabr.). The use fertilizer and kind of variety are important factors determining the yield of sweet potato. This study aims to examine the effect of manure on three varities of sweet potato and evaluate the yield of varieties test on sweet potato weevil, through choice test and no choice test.
