|
Rehm and Espig, 1991
|
|
Description | Tree growing up to 9-12 m high; fruit globular/oval, hard shell, divided internally like an orange. | Wren, 1975 |
Habitat | Cultivated mostly in India, the homeland of the tree. | Rehm and Espig, 1991 |
Uses | Fruits eaten fresh, processed
into drinks, or cut into slices and dried.
The fruit, leaves and roots are all used in traditional medicine. |
Rehm and Espig, 1991
|
Dried leaves | Two percent (w/w) admixed with
paddy rice reduced damage by natural infestations in a store by 50 percent
over a 270-day trial.
Two percent (w/w) admixed with rice reduced the level of damage caused
by natural insect infestations in a store during a six month storage period
to 2 percent compared with 10 percent in the untreated control. The main
pests were S. cerealella, R. dominica and S. oryzae. Two percent (w/w) admixed with paddy rice had no significant effect on
the development of eggs of |

RUTACEAE
Citrus aurantifolia (Christm.) Swingle. (Lime, Lima, Saure Limette)
|
Rehm and Espig, 1991 | |
Description | An evergreen shrub or much branched tree up to 5 m in height, many sharp spines on stems and beside leaves; aromatic leaves, 6-8 cm long, oval in shape; leaf stalk with narrow "wing", an extra leafy growth, edge smooth or round-toothed. Flowers white, 1-7 in a leaf axil, each about 2 cm across. Fruit round or oval, to 6 cm in diameter but usually smaller, thin, green or yellow peel, difficult to remove; pulp green, very acidic. | Bekele-Tesemma, 1993 |
Habitat | Originates from Southeast Asia (India to Japan and Indonesia); spread to almost all parts of the world; prefers warm tropical climates; main producers are the West Indies and Mexico. | Rehm and Espig, 1991 |
Uses | Edible fruit; juice, concentrate
and dried products utilised by soft drinks companies. Peel can be used to
produce pectin and aromatic citrus peel oils. Aromatic oil also produced
from the leaves. Other by-products include the citrus kernel oils and the
medicinally useful flavonoids hesperidin and naringin.
Fruit and leaves are used in traditional medicine. |
Rehm and Espig, 1991
|
Peel | Dried peel at 0.20 g/50 seeds
reduced percentage hatch of C. maculatus eggs.
5 ml/kg admixed with cowpea was ineffective at inducing adult mortality in C. rhodesianus or reducing Fl production. 7 ml/kg oil treated grain caused 100 percent mortality in adult C. maculatus after an exposure period of one hour but all activity was lost after 24 hours. |
Rajapakse, 1990
|
Constituents | Limonene was regarded as the major
volatile component.
Major fractions of peel oil include: monoterpenes (76 percent), sesquiterpenes (3.8 percent), oxygen containing compounds (18.1 percent) such as aldehydes, esters and alcohols. |
Giga and Munetsi, 1990 Don-Pedro, 1996b |
Toxicity | d-limonene has been determined
to inhibit mammary tumours in rats.
d-limonene increased activity of a detoxifying enzyme (glutathione S-transferase or GST) when given orally to mice. Increased activity of GST enhances the hosts ability to detoxify carcinogens. |

RUTACEAE
Citrus limon (L.) Burm.f. (Lemon, Citron, Zitrone)
|
|
Rehm and Espig, 1991
|
Description | Medium-sized tree, open and spreading;
almost thornless.
Several varieties, varying in size, juice content and thickness of rind. |
Graf, 1986
Wren, 1975 |
Habitat | Originates from Southeast Asia (India to Japan and Indonesia); spread to almost all parts of the world; adapted to relatively low temperatures; widely cultivated in Mediterranean countries and the United States. | Rehm and Espig, 1991 |
Uses | As for Citrus aurantifolia. | Rehm and Espig, 1991 |
Leaf powder | Two percent (w/w) admixed with wheat reduced the percentage of damage caused by T. granarium larvae to 18 percent, compared with 70 percent in the untreated control four months after introduction of the larvae. At six months, damage was 38 percent in the treated wheat and 90 percent in the control. | Jood, et al. 1993 |
Antifungal activity | 2 000 mg/kg of lemon oil in grapefruit juice suppressed growth and toxin production of A. parasiticus after an incubation period of seven days. 300 mg/kg of oil in a glucose-yeast extract medium were need to achieve the same result. | Alderman and Marth, 1976 |
Constituents | The four major components isolated
from lemon peel oil using hexane are: 5,7-dimethoxy-2H-1-benzopyran-2-one;
9-[(3,7-dimethyl-2,6-octadienyl) oxy]-7H-furol3,2-g]-[1] benzopyran-7-one;4-[(3,7-dimethyl-2,6-odadienyl)
oxy]-7H-furo[3,2-g][1] benzopyran-7-one ; and 5-[(3,7-dimethyl-2,6-octadienyl)oxy]-7-methoxy-2H-1-benzopyran-2-one.
The insecticidal potency of these compounds was less than the potency of the original oil when bioassayed against S. oryzae and C. maculatus. The last three compounds showed the greatest toxicity. Steam-volatile constituents include limonene (63.9 percent), b -pinene (12.2 percent) and g -terpinene (6.7 percent). |

Uses | As for Citrus aurantifolia. | Rehm and Espig, 1991; Perry, 1980 |
Peel | 0.25 percent (w/w) applied to wheat caused 94 percent mortality in adult S. granarius within 16 days compared to 24 percent mortality in the controls; it significantly reduced the production of F1 progeny. | El-Ghar and El- Sheikh, 1987 |

Uses | As for Citrus aurantifolia. | Rehm and Espig, 1991; Perry, 1980 |
Dried peel | Peel admixed with cowpea and dried fish chips produced an LD50 of 4 percent (w/w) for C. maculatus and 14 percent (w/w) for D. maculatus. In repellency trials, 10 percent (w/w) admixed with cowpeas or fish chips repelled both insect species. At 18 percent (w/w) on fish chips, larval emergence of D. maculatus was reduced by 60 percent; only 37 percent of the larvae developed into adults compared with 88 percent in the untreated controls. | Don Pedro, 1985 |
Dried leaves | Three percent (w/w) admixed with wheat reduced oviposition (3.7 eggs), adult emergence (9.7 insects) and prolonged development of R. dominica (52.2 days) with regards to the control (17.1 eggs, 77.3 insects and 40 days respectively). | Singh, et al. 1996 |
Antifungal activity | 2 000 mg/kg of orange oil in grapefruit
juice suppressed growth and toxin production of
A. parasiticus after an incubation period of seven days. 300 mg/kg of oil in a glucose-yeast extract medium were needed to achieve the same result. |

Dry powder | Admixture of 1.5 g/20 g cowpea
caused 46 percent mortality in adult C. maculatus within 48h and
reduced F1 production by 45 percent.
10 g/4 kg admixed with cowpea significantly reduced the percentage weight loss (0.78 percent) caused by C. maculatus with respect to the control (11.6 percent) after six months storage. |

Habitat | Widely cultivated in tropical
and sub-tropical countries.
Sierra Leone, Madagascar, Japan and Tropical America. |
Rehm and Espig 1991
|
Uses | This small, very hot red pepper is used for culinary purposes and as a traditional medicine. | Ivbijaro and Agbaje, 1986 |
Dry powder
|
Admixture of 1.5g/20g cowpea caused
30 percent mortality in adult C. maculatus and reduced F1 production
of 60 percent.
Admixture of 2 percent (w/w) with cowpea did not significantly decrease oviposition or adult emergence of C. maculatus after 10 days or percentage weight loss after 70 days when compared to the control. |
Ivbijaro and Agbaje, 1986
|
Constituents | Include capsaicin, also called capsicin. | Ayensu, 1981 |
Toxicity | Capsaicin and chilli extracts
showed evidence of mutagenicity in the Ames test, although neither induced
point mutations in mammalian cells in vitro. Capsaicin caused cytogenetic
damage in the bone marrow, and inhibited DNA synthesis in the testes, in
mice given high doses by intraperitoneal injection.
Intraperitoneal injection of 1.6 mg/kg/body weight into albino mice did not affect sperm production or development, nor did it induce dominant-lethal mutations. |

Tiwari, et al. 1995 |
Constituents | Include nicotine, nornicotine and anabasine. | Oliver-Bever, 1986 |
