Symptoms

A discussion of the internal and external symptoms caused by N. tenuis feeding on solanaceous crops is provided by El Dessouki et al. (1976). Chemical changes in plant tissue as a result of feeding by N. tenuis are detailed by Raman et al. (1984) and El Dessouki et al. (1976).

On tomatoes, adults feed on the stems, leaves and flowers, with necrosis often developing at the site of feeding (Raman et al., 1984; Al Azawi and Al Azawi, 1988). Shedding of flowers and pods in tomatoes may also be a result of feeding by this insect (Harakly, 1974).

On sesame, feeding is concentrated on the growing point, leading to stunting and loss of plant vigour (Nath, 1975).

Prevention and control

Chemical Control

Due to the variable regulations around (de-)registration of pesticides, we are for the moment not including any specific chemical control recommendations. For further information, we recommend you visit the following resources:

Impact

Although N. tenuis has been recorded as a pest of various field and glasshouse crops in Asia and Europe, little information is available on the extent of the damage it causes and the associated economic losses. In West Bengal, India, it is reported to be the most serious pest of sesame, with significant increases in crop yield resulting from the application of chemical insecticides (Nath and Pal, 1975). In Karnataka, India, tobacco plants are reported to reach infestation levels of 22.25%, with flower buds averaging 11-23 insects per bud and leaf pairs 2-5 insects per pair (Prasad et al., 1979). Screening for host-plant resistance has been conducted on about 700 cultivars of tobacco (Patel, 1980). N. tenuis is also a serious pest of bottle gourds (Lagenaria siceraria), tomatoes, and Cucurbitaceae in India (Hameed et al., 1975; Patel, 1980; Singh and Rizvi, 1993). In France, N. tenuis was first found infesting tomatoes under glass in 1986 (Malausa and Ehanno, 1988).
