TL;DR: Bos taurus indicus cattle are less susceptible to infestation with Rhipicephalus (Boophilus) microplus than Bos taurus taurus cattle but the immunological basis of this difference is not understood.

TL;DR: A 2-yr study to evaluate Louisiana and Texas sugarcane cultivars for resistance to the Mexican rice borer, Eoreuma loftini (Dyar), indicated that cultivar LCP 85-384 was significantly more susceptible than NCo 310, traditionally the most susceptible cultivar commercially produced in Texas.
Abstract: A 2-yr study to evaluate Louisiana and Texas sugarcane, Saccharum spp., cultivars for resistance to the Mexican rice borer, Eoreuma loftini (Dyar), was conducted in two locations in Texas, chosen for having different infestation levels. Criteria for assessment of resistance included percentage of bored internodes and adult emergence holes, the latter used to determine the relative impact of each cultivar on the potential areawide buildup or reduction of adult E. loftini populations. A recently released cultivar, HoCP 85-845, seemed to lose a portion of its resistance under heavy E. loftini infestation pressure, suggesting its value only in moderate-to-low infestation conditions. Cultivar CP 70-321 was the most resistant. Results indicated that cultivar LCP 85-384 was significantly (P < 0.05) more susceptible than NCo 310, traditionally the most susceptible cultivar commercially produced in Texas. In 2001, LCP 85-384, which now represents 85% of the production area in Louisiana, had the greatest m...

TL;DR: Resistance to aphid infestation in cowpea did not provide resistance to infection with CAMV, and aphids were observed to make more numerous probes and probes of shorter duration on aphid-resistant lines than on Aphid-susceptible lines.
Abstract: SUMMARY
The virus-vector-host relationships of cowpea aphid-borne mosaic virus (CAMV) and its vector, Aphis craccivora, were studied in cowpea lines differing in resistance to aphid infestation. CAMV was acquired and inoculated by its vector during brief probes, confirming that it is non-persistently transmitted. On aphid-resistant cowpea lines, the abundance and the relative sizes of aphids was less than in aphid-tolerant and aphid-susceptible lines. However, aphids were observed to make more numerous probes and probes of shorter duration on aphid-resistant lines than on aphid-susceptible lines. Resistance to aphid infestation in cowpea did not provide resistance to infection with CAMV.
