CABBAGE LOOPER CONTROL WITH DPX-E2Y45 IN DRIP IRRIGATED CUCUMBERS, FALL 2004

Fertigation Frequency for Subsurface Drip-Irrigated Broccoli

Yosef and Sagiv, 1982; Stark et al., 1983; Burt et al., 1995). However, very few studies have shown a benefit Subsurface-drip irrigation and fertigation with fluid N fertilizer of frequent or continuous fertigation compared with sources offers substantial flexibility for N fertilizer management. Fertiless frequent fertigation. Bar-Yosef and Sagiv (1982) gation events can be scheduled as often a...

Laboratory Biology of Chetogena Scutellaris (diptera: Tachinidae), a Parasitoid of Noctuidae, Reared on Fall Armyworm and Cabbage Looper

The tachinid parasitoid Chetogena scutellaris (Wulp) was reared from southern armyworm, Spodoptera eridania (Cramer), a new host record. When reared in cabbage looper, Trichoplusia ni (Hübner), (a new host) and in fall armyworm, Spodoptera frugiperda (J. E. Smith), in the laboratory, C. scutellaris developed successfully ca. 30% of the time. Success of parasitism depended on the numbers of eggs...

Growing hot pepper for cabbage looper, Trichopulsia ni (Hübner) and spider mite, Tetranychus urticae (Koch) control.

With the public perception that synthetic pesticides leave harmful residues in crop produce for human consumption, there has been increased interest in using natural products for pest control. The potential of using fruit extracts of hot pepper for controlling the cabbage looper, Trichopulsia ni (Hübner) and spider mite, Tetranychus urticae Koch is explored in this investigation. Crude extracts...

Irrigation Strategies to Minimize Nitrate Leaching for Drip Irrigated Tomatoes

Genetic Resistance to Bacillus thuringiensis Alters Feeding Behaviour in the Cabbage Looper, Trichoplusia ni

Evolved resistance to xenobiotics and parasites is often associated with fitness costs when the selection pressure is absent. Resistance to the widely used microbial insecticide Bacillus thuringiensis (Bt) has evolved in several insect species through the modification of insect midgut binding sites for Bt toxins, and reports of costs associated with Bt resistance are common. Studies on the cost...
