项目摘要

There are two strains of the citrus red mite, Panonychus citri: one is a diapausing strain that occurs only on deciduous fruit trees and the other a non-diapausing strain that occurs both on citrus and deciduous fruit trees.1. The two strains are reproductively incompatible in that no Fl adult females are produced from the cross between them. 2. Mating is common between the strains, although copulation is often broken off prematurely between C <+!゜> x DP <^!゜> . 3. There is a reciprocal difference in the reproductive incompatibility; the hatchability of the eggs from the cross between DP <+!゜> x C <^!゜> is significantly lower that between c <+!゜> x dp <^!゜> . 4. Mating is in most cases ineffective for the females that mated with a male of the other strain. In particular, for the DP females that mated first with C males, the subsequent intra-strain mating is almost entirely ineffective. 5. The DP males show a strong mating preference to the females of their strain, whereas the C males do not show any such preference. 6. Under the coexistence of both strains, the effective mating rate was lower than 50% for the females of both strains, clearly showing a mating interference between them. 7. The non-diapausing strain does not successfully overwinter on deciduous fruit trees, showing that the occurrence is due to the immigration from citrus or other evergreen trees. 8. In the intermediate latitudal zones in Japan, the two strains coexist in some pear orchards. In such pear orchards, the proportion of females in the spring DP population is very low and its occurrence is often suppressed. This seems due to an adverse effect of the inter-strain mating mentioned above.
柑橘全爪螨有两个品系:一个是滞育品系,只发生在落叶果树上;另一个是非滞育品系,既发生在柑橘上,也发生在落叶果树上。这两个品系在繁殖上不相容,因为它们之间的杂交没有产生F1成年雌性。2.交配是常见的菌株之间,虽然交配往往是过早中断之间的C <+!<^!我的意思是。3.在生殖不亲和性方面存在相互差异; DP <+!C <^!C <++之间的差异很大!x dp <^!我的意思是。4.在大多数情况下,交配对于与另一种品系的雄性交配的雌性是无效的。特别是,DP女性交配的第一个C男性,随后的菌株内交配几乎完全无效。5. DP男性表现出强烈的交配偏好,其菌株的女性,而C男性没有表现出任何这样的偏好。6.在两个品系共存的情况下,两个品系的雌虫的有效交配率均低于50%,明显表现出交配干扰。7.非滞育株在落叶果树上不能成功越冬,表明其发生是由于柑橘或其他万年青树木的迁入。8.在日本的中纬度地区,这两个菌株在一些梨园中共存。在这样的梨园,女性的比例在春季DP人口是非常低的,它的发生往往被抑制。这似乎是由于上述菌株间交配的不利影响。
