Cover Cropping for Pollinators and Beneficial Insects

Cover Cropping for Pollinators and Beneficial Insects.jpg

8/17 DOUG AND ANNA CRABTREE’S VILICUS FARM RESTS on more than 2,000 acres in northern Montana, and it is a model of how cover crops can be a foundation of pollinator and beneficial insect management. Like many farmers, their approach to cover cropping began with an interest in soil health and quickly grew to encompass much broader goals as they recognized the additional benefits cover crops could provide. “We want to implement pollinator conservation at the field-level scale,” Doug says. “Anyone can create a small wildflower strip, but as we scale up, we need conservation...

Insect Pests of Bamboos in Asia (Part 2)

INBAR_Technical_Report_No13_02..PDF32 Eggs, which are laid in clusters on the back surface of leaves in the upper crown, take about a week to hatch. Larvae remain in leaf cases for 11 months, feeding in groups at the first two instars and individually thereafter. The third instar larvae diapause in leaf cases during summer and winter months and become active in early March (Xu Tiansen 1989, 1992a; Nakahara and Kobayashi 1963). ? Crocidophora ptyophora Hampson The adult moth of this minor pest has bright yellow wings with broad purplish marginal bands. The larva rolls up green leaves with...

Insect Pests of Bamboos in Asia (Part 4)

INBAR_Technical_Report_No13_04..PDF133 This is a polyphagous species and a common pest of packing cases, plywood chests and other wood-based industrial products. It is a minor pest of dry bamboos. The adult beetle is black, 6-15 mm long, cylindrical and with a rough hooded prothorax, usually with curved hooks at the distal ends of elytra. Female adult lays eggs singly on rough surfaces of dry bamboos. The larvae, after hatching, bore into the soft portion and gradually make a wide tunnel. The tunnels are tightly packed with fine wood dust and the host bamboo is soon reduced to powder. The...

Gossypium hirsutum Merremia aegyptia Long
Description

Herbaceous, twining or creeping vine, attaining 3 m or more in length. Stems cylindrical, usually reddish, with long, erect, yellowish, non-glandular hairs. Leaves alternate, 5-palmately compound;leaflets 4-14 x 2-6 cm, oblanceolate or elliptical, the apex and base acuminate, the margins entire and ciliate, hispidulous to glabrate on both surfaces. Flowers in dichasial cymes;peduncles shorter than the petioles, hairy;bracts deciduous;sepals subequal or unequal, 1.5-2 cm long, with long, yellowish hairs;corolla funnel-shaped, white, 2.5-3 cm x 4-4.5 cm;five stamens, white;stigma bilobed, white. Fruit capsular, 4-valvate, subglobose, 1-1.5 cm in diameter, light brown, glabrous, surrounded by the persistent sepals. Four seeds per fruit, obtusely triangular, 5-6 mm long, brown, glabrous (Acevedo-Rodríguez, 2005;Austin et al., 2012).

Recognition

M. aegyptia can be easily recognized in the field by the 5-digitate leaves with entire leaflets, and the long, erect hairs covering the stems and calyx.

Impact

Merremia aegyptia is an annual climbing herb that acts as a pioneer species in disturbed sites in tropical regions. It is considered a weed in most countries where it occurs and it has been included in the Global Compendium of Weeds as an agricultural and environmental weed (Randall, 2012). The species is native to tropical America and Africa and listed as invasive in Cuba, India, Australia and Hawaii.

Hosts

M. aegyptia is a relatively common weed in sugarcane (Brazil, Lesser Antilles, Reunion) and maize fields (Guatemala, Brazil, Nigeria), where it climbs up plants, bending and entangling their stems (Standley and Williams, 1970;Fournet and Hammerton, 1991;Lima e Silva et al., 2004;Valery, 2006;Chikoye et al., 2009;Correia et al., 2010;Correia, 2016). It has also been reported in cotton (Cardoso et al., 2010), banana (Isaac et al., 2009), rice (Ismaila et al., 2015), green pepper (Coelho et al., 2013), muskmelon (Teófilo et al., 2012), yam (Fournet and Hammerton, 1991) and coffee plantations (Gavilanes et al., 1988).

Description


From PROTA (2013)

Impact

E. hypericifolia is a herbaceous shrub native to the Americas. It is regarded as an invasive weed in many of the Pacific Islands in which it occurs, especially Hawaii, where it is rated ‘high risk’. It is also a weed in Singapore and Taiwan, though the situations in which it is causing problems are not well documented. It is recognized as a weed in soyabean, sugar cane and cotton in some countries and is presumably also threatening native flora in others.

Hosts

E. hypericifolia is recorded as a weed in soyabean, sugarcane and cotton.

Gossypium hirsutum Hyoscyamus niger Long, Monitoring
Description


The entire plant is sticky, hairy and odorous (Mitich, 1992), with coarsely toothed or pinnatifid leaves that may be long petiolate or sessile and decurrent (Hocking, 1947;Williams, 1960). Depending on growing conditions and variety, the plant averages between 0.75 and 1.5m tall. The annual variety may be early or late flowering and germinates, blooms and dies during a single season. In the biennial variety, a tuber derived from the hypocotyl and the upper portion of the root (Lang, 1986) develops in the first year, giving the entire root the resemblance of a parsnip root. Sessile, yellowish-brown and purple-veined campanulate flowers are borne in several indeterminate scorpoid cymes (Halevy, 1986). The fruit, a pyxis (urn-shaped capsule with a lid-like top), dehisces to release hundreds of black/grey seeds (Hocking, 1947;Whitson et al., 2000). For further detailed descriptions of H. niger, see also Gibson (1964) and LaFantasie (2008).

Recognition


In the field, H. niger has a distinctive shape upon flowering, and developing a search image would not take much time. Surveying fields and monitoring points of entry would benefit from the use of photos, descriptions and keys, including Weeds of the West (Whitson et al., 2000), Flora of the Northeast (Magee and Ahles, 1999) and Flora of China (Flora of China Editorial Committee, 2015). An excellent description of seed characteristics can be found in Shahid Farooq and Khan (1996);however, seed size (1.5 mm long) may make detection difficult.

Impact

Hyoscyamus niger, an annual or biennial herb growing up to 1.5 m tall, is thought to have been native originally to a broad region of Eurasia. It is naturalized in many regions globally and is a noxious weed in much of North America. H. niger is cultivated as a medicinal plant in many countries, and risk of introduction is likely to be associated with commercial seed or as a seed contaminant. Once established, H. niger is capable of producing thousands of highly viable seeds per plant. However, its competitive ability appears to be limited to disturbed and cultivated areas.

Hosts


The presence of H. niger in hay affects hay quality. It is a weed of several crops, including wheat, millet and cotton (AgroAtlas, 2015), and of pastures.

Gossypium hirsutum Verbena rigida Long
Description

V. rigida grows as an herbaceous perennial plant 50-60 cm in height (ISSG, 2015). It can form dense stands via rhizomes and stolons (Munir, 2002). Leaves are arranged opposite to subopposite along the square stems and leaves clasp the stem (Tveten and Tveten, 2010;ISSG, 2015). The stiff, dark green leaves are oblong in shape, 5-10 cm long, with pointed tips and coarsely serrated edges (ISSG, 2015). Leaves and stems are covered in rough hairs (Tveten and Tveten, 2010). Cylindrical spikes of flowers forming spreading clusters are held at the ends of stems. Each flower calyx is 3-3.5 mm long and the corolla-tube is 5-10(-12) mm long (ISSG, 2015). Flowers are purple in colour and fragrant. Dry fruits separate into four, one-seeded parts. Each seed is about 2 mm long (ISSG, 2015).

Impact

V. rigida is an herbaceous perennial planted as a fast spreading groundcover (Royal Horticultural Society, 2015) and is listed as weedy in many countries (Randall, 2012). It is principally found in disturbed areas but can spread into grasslands and forests and is a weed of cotton fields (ISSG, 2015). However, there is little information on the species impact in agricultural or natural ecosystems. It spreads via rhizomes and seeds (ISSG, 2015), but the extent of dispersal by seed and whether the plant has a seedbank is unknown.

Hosts

V. rigida is a weed in pastures and cotton fields (Munir, 2002) and turf grass (Georgia Turf, 2015) but appears to be a relatively minor weed. Where a weed of cotton fields in Australia (Johnson and Hazlewood, 2002) no information was available on the magnitude of effect or what crop stage is affected. It is considered a weed in cultivation of bald cypress in Florida (Osiecka and Minogue, 2012).
